Abstract:
Andosols comprise one of the most important soil groups for agricultural activities in Japan because they cover about 46.5% of arable upland fields. In this soil group, available phosphorus (P) is accumulated by application of excessive fertilizer, but little is known about the influence of increasing P availability on microbial community diversity at large scales. We collected soil samples from 9 agro-geographical sites with Andosol soils across an available P gradient (2048.1–59.1 mg P2O5·kg−1) to examine the influence of P availability on the fungal community diversity. We used polymerase chain reaction – denaturing gradient gel electrophoresis to analyze the fungal communities based on 18S rRNA genes. Statistical analyses revealed a high negative correlation between available P and fungal diversity (H′). Fungal diversity across all sites exhibited a significant hump-shaped relationship with available P (R2 = 0.38, P < 0.001). In addition, the composition of the fungal community was strongly correlated with the available P gradient. The ribotype F6, which was positively correlated with available P, was closely related to Mortierella. The results show that both the diversity and the composition of the fungal community were influenced by available P concentrations in Andosols, at a large scale. This represents an important step toward understanding the processes responsible for the maintenance of fungal diversity in Andosolic soils.

Abstract:
The aim of this contribution was either to confirm or refuse the supposition that there are soils on the volcanic effusive rocks in the Brunt&aacute;l district which can be assigned to the referential group of Andosols. The conditions for the genesis of Andosols are described and the diagnostic criteria of the andic process are defined both according to the principles of the WBR/FAO 2006 classification and according to the Slovak MKSPS 2000 classification system. In the Czech classification system, the diagnostics of Andosols has not yet been described or defined because their occurrence on the territory of the Czech Republic has not been confirmed till now. On the Velk&yacute; Roudn&yacute; volcanic dome (780 m), samples from two profiles were taken and described: one from below the summit as a sample of forest soil, and the other from the terraced, grass-covered foot of the hill, formerly used as a ploughed land. The samples from the two profiles were processed, and analyses were carried out according to both the classification systems mentioned above. The results of the analyses were subsequently evaluated. It was discovered that both evaluated profiles conformed to most of the diagnostic characteristics of andic development according to both WRB 2006 and the Slovak 2000 classification systems. Both evaluated profiles could be then classified &ndash; according to WRB 2006 &ndash; as Vitric Andosol (Dystric) and Vitric &ndash; Umbric Andosol (Dystric, Colluvic), respectivelly; according to Slovak Classification System as Andic Cambisols. The occurrence of soils with andic development in the Czech Republic was thus confirmed. The conclusion drawn by some authors (eg. in US Taxonomy) that a higher content of volcanic glass and a substrate of andesite type are not an indispensable condition for the creation of soils classified as Andosols was also confirmed. Likewise, according to the WRB criteria, a melanic humus horizon is not a necessary condition. Because of the difficulties in distinguishing the types, the Czech classification system recommends that a humic andic horizon should be evaluated as molic. We assume that in some cases it could be better classified as umbric. A preliminary proposal has been put forward to insert the Andozem soil types in Taxonomic Soil Classification System of the Czech Republic: Haplic Andosol, Vitric Andosol, Lithic Andosol, Umbric Andosol, but the properties and criteria of those soils will have to be defined precisely. One problem which will also have to be resolved is how to allocate the profiles displaying andic properties either to the proposed subtype of Cambic Andosol or to the subtype of Andic Cambisol (outside the referential class of Andsols). This issue is, indeed, not dealt with satisfactorily either by the Slovak system or the worldwide WRB 2006 classification, either.

Abstract:
Sorption of oxyanions by soils and mineral surfaces is of interest due to their role as nutrients or pollutants. Volcanic soils are variable charge soils, rich in active forms of aluminum and iron, and capable of sorbing anions. Sorption and desorption of vanadate, arsenate, and chromate by two African andosols was studied in laboratory experiments. Sorption isotherms were determined by equilibrating at 293 K soil samples with oxyanion solutions of concentrations between 0 and 100 mg L−1 V, As, or Cr, equivalent to 0−2.0 mmol V L−1, 0−1.3 mmol As L−1, and 0−1.9 mmol Cr L−1, in NaNO3; V, As, or Cr were determined by ICP-mass spectrometry in the equilibrium solution. After sorption, the soil samples were equilibrated with 0.02 M NaNO3 to study desorption. The isotherms were adjusted to mathematical models. After desorption with NaNO3, desorption experiments were carried out with a 1 mM phosphate. The sorption of vanadate and arsenate was greater than 90% of the amount added, while the chromate sorption was much lower (19–97%). The sorption by the Silandic Andosol is attributed to non-crystalline Fe and Al, while in the Vitric Andosol, crystalline iron species play a relevant role. The V and Cr sorption isotherms fitted to the Freundlich model, while the As sorption isotherms conformed to the Temkin model. For the highest concentrations of oxyanions in the equilibrating solution, the sorbed concentrations were 37–38 mmol V kg−1, 25 mmol As kg−1, and 7.2–8.8 mmol Cr kg−1. The desorption was low for V and As and high for Cr. The comparison of the sorption and desorption isotherms reveals a pronounced hysteresis for V in both andosols and for Cr in the Silandic Andosol. Phosphate induced almost no V desorption, moderate As desorption, and considerable Cr desorption.

Abstract:
The sowing-to-harvest period for the medicinal plant Ginseng (Panax ginseng Meyer) is 4–6 years. Although one of the primary soils used to cultivate ginseng in Japan is Andosol, there have been few studies of the changes in the soil’s chemical properties during the cultivation of ginseng in Andosol soil. Here, we investigated the chemical properties of Andosol soil by collecting soil samples from cultivation sites with various numbers of years of ginseng cultivation. A significant negative correlation was observed between the years of cultivation and the soil’s pH, indicating that soil acidification increased with an increasing number of years of cultivation. Similarly, exchangeable calcium (Ca) showed a significant negative correlation with the years of cultivation. The soluble aluminum (Al) concentration showed a significant positive correlation with the years of cultivation and was significantly negatively correlated with the exchangeable Ca and magnesium (Mg) contents. These results suggest that a decrease in pH due to Ca absorption by ginseng, increasing Al dissolution, and a further accelerated decrease in pH occur during the cultivation of ginseng in Andosols. The increase in soluble Al with increasing years of cultivation also affected the dynamics of essential trace elements in the soil, showing significant negative correlations with the soil’s soluble copper (Cu) and zinc (Zn) contents, indicating that the Cu and Zn contents decreased with increasing Al. Our findings indicate that in the cultivation of ginseng on Andosol soil, the soil’s soluble Al content is an essential factor in changes in the soil’s chemical properties.

Abstract:
Sweet potato is a food and nutrition security crop in sub-Saharan Africa with low yields resulting from soil infertility. We examined the effects of nine fertilizer regimes on the growth performance of orange-fleshed (OFSP) and white-fleshed (WFSP) sweet potato varieties in two agro-ecological zones characterized by Andosol and Nitisol soils. The treatments were: NPK20-10-10, NPK6-15-28, rice husk biochar (RHB), fast compost (FC), Tithonia diversifolia leaf powder, poultry litter (PL), RHB/NPK20-10-10, FC/NPK20-10-10 and PL/NPK20-10-10. These were compared to a control of no fertilizer. The Andosol and Nitisol soils were acidic with significant differences (p < 0.05) in total nitrogen, organic carbon, C/N ratio, phosphorus, potassium, calcium and magnesium. Fertilizer effects were dominant on the adventitious root, total and marketable yields, moderately affecting main stem length and harvest index (HI) with weak effects on branch number, petiole length and leaf area index (LAI). Soil type and sweet potato variety strongly affected main stem length and HI. Variety × fertilizer strongly influenced adventitious root formation, while soil × variety × fertilizer affected total and marketable yields. LAI, primary branch number, dry biomass, total and marketable yields were best for the OFSP in the Andosol, while main stem length, petiole length, adventitious roots and HI were best for the WFSP in the Nitisol. Results of the study showed that FC, PL/NPK20-10-10 and RHB/NPK20-10-10 were the most promising soil fertility amendments to boost sweet potato productivity in the Nitisols and Andosols.

Abstract:
Abstract The analyses for the description of physic-chemical and humus fractional characteristics have been determined for two soil subtypes, respectively four soil profiles, that are representative for the lower altitudes area of Giurgeu Mountains. The analysis has been based on: one Andi-Eutric Cambisols (EC an- 920 m alt.) and three Cambic Andosols (AN ca) situated at different altitudes: 1120-1140 m, 1197 m and 1310 m. The purpose of the research is to indentify some quantitative and qualitative differences in regards to some organic and inorganic components from the soil. Have come into prominence the sum of exchangeable bases, the total acidity exchange, the degree of base saturation and other aspects related to organic accumulation (the highest in Cambic Andosols: 1120-1140 m alt.), degree of humification (higher for the same Andosol and variable for the one from 1310 m alt.), the distribution curve on the profile of chemical and biochemical humic components. In terms of quality, there are differences in regard to the humification degree of organic matter, the dynamic on the profile of the main humus fractions (humic acids, fulvic acids, non-extractable material) forming the horizons of accumulation for some of the fractions.

Abstract:
Volcanic soils are important resources because of their unique mineralogical and physical characteristics, and allophanic Andosols represent some of the world’s most fertile soils. However, their unique properties can be lost when cultivated. Most soils in the Central Valley, Mexico, are derived from volcanic materials. This valley encompasses one of the largest water supply systems in the world by volume, but is affected by soil degradation and deforestation. Sustainably managing volcanic soils requires understanding how land use affects their hydrodynamic properties. Gas adsorption and mercury intrusion porosimetry, water retention curves, tension infiltrometry and X-ray tomography were used to describe pore structure characteristics. Two volcanic soils (one Andosol and one derived from indurated tuff – Tepetates), three land uses (maize monoculture, maize–wheat rotation and fallow) and two horizons (Ap and A2 for maize monoculture and maize–wheat rotation) were studied. Tillage affected topsoil by increasing the sand fraction by 38% and decreasing total porosity and macroporosity by 23% and 40% respectively. Macropore size was reduced and the number of isolated macropores was higher in the tilled layer under maize, compared with untilled subsoil. The plot under maize–wheat rotation had lower allophane content, and saturated hydraulic conductivity was reduced by nearly an order of magnitude and water retention by half, compared with maize and fallow plots. Compared with Andosols, Tepetates showed differences in mineralogical composition with lower contents of amorphous compounds and in its porous network characteristics with twice the total and percolating macroporosity compared with the maize plot. Its high content of organic carbon (3.5%) seemed beneficial for its hydrodynamic properties. Sustainable agricultural management of these volcanic soils requires reducing mechanised tillage, avoiding periods when soil is bare, not applying maize–wheat rotation and applying maize–fallow rotation allowing natural vegetation growth.

Abstract:
The amount of medical waste, especially infusion bottles, is a problem for environmental pollution. Improper management of infusion bottle waste can have an impact on disease transmission. The medical waste treatment used high technology and high costs will be a financial burden, so simple and effective treatment innovations is needed. This study uses an experimental method of removing bacteria from infusion bottles using a mixture of water and Andoso soil as a solution for washing infusion bottle waste. The soil solution concentration used in washing was 45% with a contact time of 2 minutes. The experiment was carried out with two repetitions. The treatment effect on decreasing the number of bacteria using a multiple linear regression mathematical model. The results showed that the disinfection process of bacterial-contaminated infusion bottles using water required rinsing up to six times, whereas using 45% andosol soil solution only rinsed once. The effectiveness of the disinfection of infusion bottles contaminated with bacteria using soil solution reduces the number of bacteria by 98%.

Abstract:
This study discusses penetration resistance (PR) of forested Pumice-Andosol sites. PR, a key soil property influencing root growth and elongation, exerts a substantial influence on ecological site quality and tree growth. Andosols were expected to show low PR because of their unique characteristics (low bulk density, loose soil matrix). Five sites, two undisturbed and three backfilled, were sampled. The latter result from pumice excavation and were examined to quantify potential PR alterations in the aftermath of backfilling and pumice removal. Penetrologger sampling on undisturbed sites showed mean PR not exceeding 3 MPa, a literature-based, critical threshold restricting root growth, in the upper 0.80 m, indicating conditions fostering tree rooting. Backfilled sites mostly exhibited increased (> 3 MPa) PR, leading to rooting restrictions even beginning at −0.21 m. Deviations from undisturbed soils range from −15.6 to +109.3% depending on depth and age of the backfilled site. Furthermore, GIS-based data interpolation helped to identify spatial PR patterns and allowed a direct comparison before/after backfilling at one site. Statistical analysis revealed significantly altered PR after backfilling, while a concluding ANOVA provided at least significant governing factors (depth, area, clay + silt content, soil organic matter), albeit with only small effect sizes.

Abstract:
No tillage (NT) fosters carbon (C) sequestration, increases soil organic matter (SOM) stock, and improves soil health. However, its effect on SOM accumulation in Andosol, which has high OM stabilization characteristics due to its specific mineral properties, remains unclear. In this study, we evaluated the effect of NT on SOM content and its distribution by the physical fractionation method and assessed the quality of accumulated SOM in each fraction. We collected soil samples at 0–2.5, 2.5–7.5, and 7.5–15 cm depths from NT and conventional tillage (CT) plots in a long-term (19 years) field experiment of Andosols in Ibaraki, Japan. The soil samples were separated into light fraction (LF), coarse-POM (cPOM: 0.25–2 mm), fine-POM (fPOM: 0.053–0.25 mm), and silt + clay (mOM: <0.053 mm). The C, nitrogen (N), and organic phosphorus (Po) contents of each fraction were analyzed. The C content of cPOM and fPOM in NT at 0–7.5 cm was higher than in CT, while there was no clear difference in the mOM fraction or deeper layer (7.5–15 cm). NT increased the C, N, and Po contents in the labile POM fractions at the surface layers but did not increase the stable fraction or change the quality.

Full text
Abstract:
Le chlordécone est un pesticide organochloré, qui a été utilisé dans les Antilles françaises pour lutter contre le charançon du bananier Cosmopolites sordidus. Ce pesticide a été interdit en 1993 en raison de sa toxicité et de sa persistance dans l'environnement. Cependant des études ont montré que la population antillaise continue d'être exposée (lait maternel et sang contaminés, transfert de chlordécone mère-jeune, retard du développement cognitif, risque de cancer de la prostate) en particulier via l'alimentation. Depuis 2008, la réglementation européenne n°396/2005 est appliquée sur le territoire antillais (limite maximale fixée à 10 et 20 µg chlordécone /kg poids frais repsectivement dans le foie et l'oeuf et de 100 µg/kg de matière grasse dans le gras). Il s'avère que la contamination des denrées au chlordécone est due au fait que les sols d'anciennes bananeraies autrefois traités au chlordécone (principalement des andosols, des nitisols et des ferrisols) demeurent contaminés. L'andosol contient de l'argile allophane, structure qui confère une microporosité élevée par l'enchevêtrement de motifs particulaires répétés à plusieurs échelles. Le chlordécone de l'andosol a été potentiellement piégé par ce réseau de micropores et est supposé être fortement retenu. Au contraire, le nitisol contient de l'argile halloysite, dont la structure correspond à une superposition de couches et ménage une faible porosité. Notre hypothèse est que le chlordécone est moins retenu par le nitisol que par l'andosol. Les animaux monogastriques élevés en plein air (porcin, volaille) sont susceptibles d'ingérer du sol de manière involontaire. Chez la poule pondeuse, les niveaux d'ingestion de sol peuvent atteindre 25 % de la ration alimentaire journalière dans le cas d'une réduction du couvert végétal et/ou d'un rationnement alimentaire. L'ingestion de sol pour le porcin a été peu étudiée. Nous avons cherché à déterminer les aptitudes d'un andosol et d'un nitisol à retenir le chlordécone durant le processus digestif. Pour cela nous avons évalué la biodisponibilité relative du chlordécone d'un andosol et d'un nitisol chez l'animal monogastrique. La détermination de la biodisponibilité relative repose sur la comparaison des pentes entre la réponse (concentration de chlordécone dans les matrices animales) obtenue lors des doses croissantes de chlordécone ingérées via la matrice testée (l'andosol ou le nitisol) à la réponse obtenue lors des mêmes doses de chlordécone ingérées via une matrice de référence (huile). Les résultats obtenus chez la poule pondeuse et le porcelet ont indiqué que l'andosol et le nitisol n'affectent pas la biodisponibilité du chlordécone. Ainsi, la biodisponibilité relative du chlordécone des sols étudiés a été identique et considérée égale à 100% aussi bien chez la poule que chez le porcelet. Le chlordécone du sol a donc été extrait durant le processus digestif et absorbé par l'animal monogastrique à l'identique du chlordécone dissous dans de l'huile. Le chlordécone du sol est donc assimilable par l'animal d'élevage. Ainsi, les sols contaminés en chlordécone présentent un réel risque pour la filière animale. Les teneurs en chlordécone des produits (foie, gras, oeuf) ont dépassé les limites maximales acceptables dès lors que les animaux monogastriques ont ingéré 6,8 µg chlordécone /jour/kg de poids vif. Sachant que 10% des sols cultivables contiennent au moins 1 mg chlordécone /kg, dès lors qu'un animal monogastrique (poule pondeuse ou porcelet) ingère 17 % de sol dans sa ration alimentaire quotidienne, les teneurs en chlordécone des produits dépasseront les limites maximales et seront « impropres » à la consommation. Il convient ainsi d'identifier les pratiques d'élevage à risques pour préconiser des mesures limitant la contamination des produits animaux au chlordécone
Chlordecone (CLD) is an organochlorine pesticide used in the French West Indies against black weevil Cosmopolites sordidus. This pesticide was banned in 1993, because of the toxicity and persistence of this compound in the environment. However, several studies indicated that the population is already exposed to chlordecone (contaminated blood and maternal milk, chlordecone transfer to the mother from the child, memory delay in child and risk to the prostate cancer) particularly by food ingestion. Since 2008, European Regulation °396/2005 is applied in French West Indies (maximal limit fixed at 10 and 20 µg chlordecone/kg of fresh weight in liver and egg and at 100 µg chlordecone /kg of fat in fat). Soils of banana crops previously treated by chlordecone (mainly andosols, nitisols, ferrisols) are still contaminated and are the major source of contamination of food products. Andosol contains allophane clay structure which allows a high microporosity with the formation of particle aggregates in a pattern repeated at different scales. chlordecone would be strongly trapped by this micropores structure and supposed to be strongly retained. Nitisol contains halloysite clayed structure composed to the clay layers superposition with a low porosity. Our hypothesis is that chlordécone is less retained by nitisol than by andosol. Monogastric animals reared outside (pig, poultry) may involuntary ingest soil. It has been shown that hen can ingest soil amounts corresponding to 25 % of the daily ration in the case of vegetation reduction and of nutritional imbalance. Soil ingestion by pig was less studied. In the frame of this research work, we determined andosol and nitisol capacities to retain chlordecone during the digestive process. The relative bioavailability of soil-bound chlordecone in monogastric farm animals (laying hen and juvenile swine) was established. The relative bioavailability determination consists to the slope comparison between the response (concentrations of chlordecone in animal matrices) obtained with increasing chlordecone doses via andosol or nitisol and the response obtained with the same chlordecone ingestion doses via a reference matrix (oil). Results showed that andosol and nitisol did not reduce the chlordecone bioavailability. Thus, relative bioavailability of soil-bound chlordecone was considered to be equal to 100% in laying hen and in juvenile swine. chlordecone was extracted during the digestive process and was absorbed by the monogastric animals. Thus, soil-bound chlordecone is directly assimilated by monogastric farm animals. Concentrations of chlordecone in animal products (liver, fat, egg) exceeded maximal limits for a chlordecone ingestion at least equal to 6.8 µg chlordecone/day/kg of body weight. Since 10% of agricultural soils are contaminated with at least 1 mg/kg, the ingestion of 17% of soil in the daily food ration will result in animal products not acceptable for human consumption. Therefore, it is important to characterize the risk livestock farming practices in order to limit the contamination of food products

L'objectif de ce travail est d'etudier la fixation des phosphates par un horizon sl d'un andosol desature non perhydrate de la reunion. L'effet de la concentration initiale et de la quantite initiale des phosphates sur la cinetique de fixation et sur la liberation concomittante des hydroxyles, des silicates et de l'aluminium ont ete mis en evidence. Les phosphates sont apportes sous forme de solution de kh#2po#4. La fixation augmente fortement avec l'augmentation des apports de phosphates. La capacite maximale de fixation, determinee par l'equation de langmuir est de 39770 mg de p par kg de sol. Mais, l'utilisation du modele par solution-solide montre que 75% environ de la quantite maximale reellement fixee sont sous forme de phosphates d'aluminium precipites. L'etude de la liberation des ions hydroxyles et de la silice montre que les ions orthophosphates sont adsorbes sur les sesquioxydes et sur les allophanes par echange de ligand avec les groupes hydroxyles et les molecules d'eau. La quantite de phosphates extractibles au reactif olsen-dabin est proportionnelle a la quantite de phosphates fixes. Au cours du vieillissement, une faible partie du phosphate assimilable retrograde. La deshydratation, la destruction de la matiere organique et le chaulage provoquent une augmentation de la vitesse initiale de fixation, la capacite de fixation variant peu. Sur les sols deshydrates et ceux ou la matiere organique a ete detruite, une augmentation de la desorption est observee. Les analyses montrent a l'echelle nanoscopique une forte heterogeneite chimique.

Abstract:
Le nématode phytoparasite Radopholus similis est un ravageur majeur des bananiers et plantains dans le monde. Introduit à partir du XVIe siècle en Afrique et Amérique, ce nématode occasionne des pertes importantes dans les bananeraies traditionnelles. La mise au point de nouvelles méthodes culturales a permis de réduire son impact ; mais des connaissances supplémentaires sont requises pour comprendre sa persistance et prévenir sa dispersion. Considérée jusqu'alors comme marginale, la phase sol de R. similis avait été peu étudiée car les populations de R. similis sont faiblement concentrées dans le sol (environ 1/1 000e de celle des racines). Pourtant, le volume du sol exploré par les racines de bananier représente 100 à 300 fois le volume de ces racines ; la phase sol concerne 30 à 50 % des effectifs de R. similis. Après avoir considéré les caractéristiques des sols volcaniques antillais, et notamment les classes de capillaires susceptibles d'héberger R. similis (capillaires de 20 à 300 µm de diamètre), nous avons évalué les différentes méthodes d'extraction des nématodes : filtration Baermann, élutriation, centrifugation-flottaison, aspersion, macération dans l'eau oxygénée. Les rendements à l'extraction de chaque méthode, leurs avantages et inconvénients ont été discutés. Ce travail a été complété par l'évaluation d'une méthode de coloration vitale qui permet de discriminer les nématodes morts et vivants. L'aptitude à la survie de R. similis dans le sol a ensuite été évaluée. Pour cela, nous avons déposé des suspensions de nématodes dans des piluliers remplis de sol de natures et de potentiels matriciels variables, mais toujours sans ressource alimentaire. Ces piluliers ont ensuite été conservés jusqu'à 180 jours dans des conditions de température optimale pour R. similis. Les durées de survie mesurées ont ainsi été légèrement supérieures à celles que l'on trouve habituellement dans la bibliographie : si on exclut les sols saturés en eau, il restait au bout de six mois de 1,7 à 9,3 % de la population apportée dans le nitisol et de 9,5 à 11,9 % dans l'andosol. Pour les adultes, les courbes de décroissances de population de R. similis pouvaient généralement être ajustées à l'aide des modèles de décroissance exponentielle ou de Teissier. Ces courbes dépendaient de la nature du sol, du potentiel hydrique et du sexe. Nous avons ainsi observé que les mâles avaient une capacité de résistance surprenante ; dans le nitisol, les taux de survie ont été en moyenne proches du double de ceux des femelles. Cette capacité de survie des mâles serait liée à une moindre dépense énergétique journalière que chez les femelles : les mâles, dont le système digestif est atrophié, ne chercheraient pas activement leur nourriture et ne perdraient pas de réserves lors du développement des œufs. Par ailleurs, dans les sols stérilisés, la survie était optimale quand les sols étaient proches de la capacité au champ ; dans les sols non perturbés, elle était optimale dans les sols les plus secs. Ces résultats contradictoires pourraient s'expliquer par les interactions avec les autres organismes du sol qui, en diminuant la capacité de survie, pourraient avoir un rôle antagoniste. Une étude complémentaire a été réalisée dans des tubes remplis d'eau ou de solutions de sol, extraites d'un nitisol par centrifugation. Au bout de 35 jours, il restait 7 à 8 % des populations initiales de R. similis, et ce, pour les deux sexes. Cette espèce peut donc subsister assez longtemps dans des eaux qui circulent pour être disséminée par ruissellement. Nous avons donc étudié la dissémination de R. similis par les flux d'eau ; en surface à l'aide de simulateur de pluie, en profondeur à l'aide de cylindres de sol sur lesquels nous avons simulé des pluies allant jusqu'à 3,7 fois le volume poral du cylindre (pluie de 540 mm). Ces études ont été complétées par un dispositif au champ qui a permis de cartographier les recontaminations dans des parcelles isolées ou non hydrologiquement par des fossés. La dissémination passive a été très faible dans le sol et n'a concerné qu'une fraction marginale des populations. Il semble que R. similis ait adapté ses comportements pour résister à l'entraînement par les eaux (plasticité réflexe ?). En surface, les simulations de pluie ont montré que la dissémination par les eaux nécessitait des conditions bien particulières : sols proches de la saturation en eau, racines ou bulbes arrachés à la surface du sol. Néanmoins, la dissémination passive existe, essentiellement en surface ; elle s'apparente à un phénomène restreint aux évènements "catastrophe" à l'échelle du nématode : destruction de son milieu de vie par les intempéries accompagnées d'épisodes de ruissellement important. Elle est suffisante pour entraîner la recontamination d'une parcelle en moins de deux ans. L'ensemble de ces travaux a montré que le comportement de R. similis est un facteur essentiel pour comprendre sa survie et sa dispersion. Sa biologie lui permet de bien s'adapter aux cultures pérennes à multiplication végétative, comme le bananier. Lorsque ces dernières sont cultivées en monoculture, les dégâts peuvent être considérables.

Abstract:
Les andosols dérivent de cendres volcaniques. Leur originalité réside dans la présence d’allophane, argile amorphe aux rayons X et de charge nette positive. Ce colloïde minéral, par le très fort pouvoir de rétention vis­à-vis d’anions et par sa capacité d’hydratation, règle le flux d’énergie d’une manière très efficace dans ce type de sol énergie. Les anions énergétiques sont ainsi soustraits au catabolisme microbien. Il en est de même des enzymes, et parmi elles, les déshydrogénases adsorbées par le complexe colloïdal. Un apport de P minéral libère ces deux groupes de substances. Des investigations ont été menées à partir d’échantillons de l’Ile de la Réunion et de la Grande Comore. Les recherches ont essentiellement été orientées dans trois directions : capacité d’un échange hydrique des andosols assortie des relations entre la minéralisation du C et les conditions physiques ambiantes, effet de l’apport de Pm, activité déshydrogénasique. L’exploration couvre des durées d‘incubation courtes : de 1h à 5j. Cette première phase, peu explorée, montre qu’il s’agit là de remaniements métaboliques originaux et non pas simplement d’une préfiguration chronologique des résultats obtenus aux temps plus longs : 5 à 35 jours. A cet effet, des chambres d’incubation originales ont été construites. Les résultats obtenus ont fourni un ensemble cohérent faisant ressortir la complexité des équilibres; autour de l’allophane et permettant de formuler des recommandations de pratique culturale pour une meilleure mise en valeur de ces sols
Andosols proceed from volcanic ashes. Their originality lies in the presence of allophane, a clay which is amorphous to X-rays and with a net positive charge. This mineral colloïd, through its very strong retention power towards anions and its hydratation capacity, regulates the energy flux in this type of soil very efficiently. The energetical anions are thus removed from the microbial catabolism. The same holds true with enzymes, and among them, the dehydrogenases adsorbed by the colloïd complex. An input of mineral P releases these two groups of substances. Research has been done on samples from la Réunion and the great Comoro Islands. These investigations have been essentially oriented in three directions: water-exchange capacity of andosols as 1inked to the relations between C mineralization and the physical ambiental conditions, the effect of a Pm input on dehydrogenase activity. The exploration covers short incubation periods from 1h to 5d. This first phase, little explored, proves that there are original metabolic rearrangements and not simply a chronological prefiguration of the results obtained on longer terms: 5 to 35d. For that purpose, original incubation chambers have been constructed. The results thus obtained yielded a coherent whole which demonstrated the complexity of equilibria around the allophane and which allows us to express recommendations related to agricultural practice towards an improved development of these soils

Abstract:
La compréhension des processus qui participent au devenir du nitrate dans les sols volcaniques du bassin élémentaire de « la Loma », est essentielle afin de répondre aux interrogations concernant l'impact des activités agricoles sur la qualité des eaux et définir des stratégies de protection des ressources en eau du bassin de Valle de Bravo. Ce dernier, à activités majoritairement agricoles, approvisionne pour 15% des besoins en eau potable de la zone métropolitaine de la ville de Mexico. Le sol de « la Loma» est un Andosol, avec une minéralogie caractérisée par des composants amorphes comme l'allophane. Le sol présente une charge variable, dont sont responsables les allophanes et la matière organique. L'adsorption du nitrate dans le sol, étudiée de façon statique et dynamique, est linéaire et instantanée dans l'intervalle de concentrations étudiées (4 à 20 mM). La structure du sol et la géométrie du réseau poral influent fortement le transport des solutés. Le labour affecte la structure et le réseau poral des 30 premiers cm du profil de sol. Les essais d'infiltrométrie ont mis en évidence deux comportements différents dans le profil de sol: en surface aucune méthode d'analyse n'a marché du fait de la forte variation spatiale des propriétés de sol suite aux activités agricoles; en profondeur la conductivité hydraulique varie de 0. 006
Understanding nitrate fate processes in the volcanic soils of an elementary catchment "La Loma", is necessary to evaluate the impact of agricultural activities on the water quality and to define strategies to protect the water resources of the Valle de Bravo basin. This agricultural basin provides 15% of drinking water supplied to the metropolitan zone of Mexico City. The soil of "La Loma" is an Andosol, with a mineralogy characterized by amorphous constituents like allophane. The soil presents variable charge; where allophane and organic matter are the main contributors. Nitrate adsorption in the soil, studied in a static way and dynamic way, is linear and instantaneous in the concentrations range studied (4 to 20 mM). Soil structure and pore network geometry strongly influence the fate of dissolved nutrients. Solute transport through packed and intact columns shows two different behaviors: physical equilibrium and non-physical equilibrium respectively. Tillage practices affect the structure and the pore network of the first 30 cm of the soil profile. Infiltrometry tests highlighted two different behaviors in the soil profile: at the soil surface none of the analysis methods gave good results due to the high spatial variability of the soil properties following the agricultural practices; in depth the hydraulic conductivity varies from 0. 006

Abstract:
Cette étude visait à déterminer les caractéristiques d'altération comprenant la genèse et la formation de sols sur les pyroclastes de l'Île de Trindade (IT), Atlantique Sud, Brésil. Les échantillons ont été prélevés au Vulcão do Paredão de l'Holocène (profil P1) et dans la Formation Morro Vermelho du Quaternaire ancien (profils P2, P3 et P4). Les pyroclastes de P1 et P2 sont dépôts de brèches volcaniques, tandis que P3 est un dépôt de lapilli. P4 présente des fragments de roches avec une composition minéralogique différente des autres profils suggérant un autre événement de dépôt de bombes pyroclastiques. Les éruptions associées peuvent être considérées comme stromboliennes. Analyse au microscope optique soutenue par la diffraction des rayons X indiquent un mélange de biotite, de goethite, d'ilménite, d'anatase, de magnétite, d'hématite, de pyroxènes, de zéolites et d'olivine comme minéraux principaux. La microscopie optique montre un sidéromélane qui se transforme en palagonite, indiquant une éruption phréato-magmatique. La microscopie infrarouge dans les zones palagonitisées a identifié l’halloysite, probablement issue de l'altération du sideromélane. Les amygdales et les microfractures sont partiellement ou totalement remplies de zéolites, formées par la percolation de l'eau qui réagit avec la palagonite et la précipitation des éléments chimiques du fluide hydrothermal. Les magnétites-Ti et l’iddingsite sont observées dans les fractures et en bordure des olivines. La progression de l'altération dans le profil du sol, se manifeste par la présence de reliques d'olivine ou sa transformation totale dans les horizons supérieurs, et montre que l'altération est le processus principal de formation des iddingsites. Certaines magnétites-Ti sont zonées avec un enrichissement en Cr au centre, suggérant une origine mantellique. L'augite et le diopside expliquent les teneurs élevées en éléments traces. Les données géochimiques montrent que les pyroclastes sont ultrabasique et föiditique. Les sols de P1 et P2 comportent, respectivement, les horizons A, Bi, C et un A érodé, C, tandis que P3 et P4 sont constitués des horizons A et C. Les sols montrent une matrice argileuse rougeâtre et brunâtre et sont friables avec une consistance plastique. Leurs microstructures sont granulaires, simples microaggrégats de grains et d'intergrains et, les aggrégats sont indifférenciés. Les constituants minéralogiques de la roche sont la biotite, l'hématite, la magnétite, l'ilménite, les pyroxènes, l'olivine, l'halloysite, la goethite, l'anatase et le rutile. La fraction argileuse est marquée par la présence d'halloysite, de ferrihydrite et de petites quantités d'allophane. Tous les sols peuvent être classés comme Andosols non-allophaniques. La prédominance de l'halloysite suggère que l'allophane serait une phase intermédiaire issue de l’altération rapide du sidéromélane favorisée par les conditions climatiques de l’IT. La géochimie totale montre que dans tous les profils Al, Fe et Ti s'accumulent en raison de leur faible mobilité et que Ca, Na, K et Mg sont les plus intensément lixiviés. Les profils des altitudes inférieures présentent des valeurs en K et Mg plus élevées dans l'horizon A en raison de l'influence des projections salines et de dépôt d'éléments chimiques des niveaux supérieurs. Pour P1 et P3, les éléments Ti, Mn, Fe, Co, Cr, Ni, V, Zr, S ont été enrichis dans les sols et leurs concentrations relatives sont liées à perte d'éléments mobiles pendant le processus de formation du sol. Zn et Cu se concentrent sur un horizon A de profils P3 et P4 avec une concentration plus élevée de matière organique et des fragments de pyroclastes inaltérés. Le lixiviation des terres rares de haut vers la pente inférieure a conduit à l'enrichissement de ces éléments, en particulier des terres rares légers, dans un sol à basse altitude. Le profil de haute altitude a montré une anomalie positive en Ce due à une exposition plus longue aux intempéries
This study aimed to characterize the alteration features comprising the genesis and formation of soils on pyroclasts of Trindade Island (TI), South Atlantic, Brazil. Collections of samples were made at the Holocene Paredão volcano (Profile P1) and the Late Quartenary Morro Vermelho Formation (profiles P2, P3 and P4). The pyroclasts of P1 and P2 are volcanic breccia deposit, whereas of P3 is a lapilli deposit. P4 presents fragments of rocks with mineralogical composition different from other profiles suggesting another event of deposition of pyroclastic bombs. The eruptions associated can be regarded as strombolians. Optical microscope supported by X-ray diffraction analysis revealed a mixture of biotite, goethite, ilmenite, anatase, magnetite, hematite, pyroxene, zeolites, and olivine as their main mineral components. Petrologic analysis shows sideromelane that changes to palagonite, indicating a phreatomagmatic eruption. Infrared analyses in the palagonitized regions revealed the presence of halloysite, suggesting alteration of sideromelane to tubular clay minerals. Amygdales and microfractures are partially or totally filled with zeolites, which are formed by the percolation of water that reacts with the palagonite and precipitation of chemical elements of hydrothermal fluid. Iddingsite and Ti-magnetites occur in the fractures and edges of the olivine. The advance of the alteration towards the soil profile, leaving only relicts of olivine or reaching their total transformation in the upper horizons, shows that weathering is the main process of iddingsite formation. Some Ti-magnetites are zoned with Cr-rich core and Cr-poor edge, suggesting a mantelic origin. The augite and diopside explain the high trace elements contents. Geochemical data show that the pyroclasts are plotting in the ultrabasic and foidites. The soils of P1 and P2 show, respectively, A, Bi, C and decapitated A, C horizons; and P3 and P4 show A and C horizons. The soil profiles show a reddish and brownish clayey matrix and are friable with a plastic consistency. Their microstructures are granular, simple grain and intergrain microaggregate and, the aggregates show undifferentiated b-fabric. The mineralogical constituents of the bulk fraction are biotite, hematite, magnetite, ilmenite, pyroxene, olivine, halloysite, goethite, anatase and rutile. The clay fraction is marked by presence of halloysite, ferrihydrite and little amounts of allophane. All soils can to be classified as non-allophanic Andosols. The predominance of halloysite formed by alteration of sideromelane, suggests that allophane would be an intermediate phase of this rapid transformation favored by climate conditions of the TI. Total geochemistry showed that in all profiles Al, Fe and Ti accumulate due to their low mobility and Ca, Na, K and Mg are the most intensely leached. The profiles located at the lower quotas have higher K and Mg values in A horizon due to the influence of salt sprays and the deposition of chemical elements from the higher regions. Ti, Mn, Fe, Co, Cr, Ni, V, Zr, S were enriched in soil profiles P1 and P3 due to loss of mobile elements during the soil formation process. Zn and Cu concentrate on A horizon of profiles P3 and P4 with higher concentration of organic matter and fragments of unaltered pyroclasts. Leaching of the rare earth elements from higher to the lower slope led to the enrichment of these elements, especially the light rare earth elements, in the low-lying soil. The high-altitude profile showed Ce positive anomaly due to longer exposure to weathering
