Texto completoCom base no procedimento EPA-3050B, estudou-se o teor de metais (Cd, Cr, Cu, Ni, Pb, e Zn) em lodos de esgoto da CETESB. Foram analisadas duas amostras e os resultados obtidos foram (Cd =3,4 ; Cr =367,5 ; Cu =263,0 ; Ni=290,6 ; Pb =91,5 ; Zn =1324,9 mg/ kg) para primeira amostra e (Cd =3,0 ; Cr =332,2 ; Cu =190,5 ; Ni=274,6 ; Pb =82,5 ; Zn =1284,2 mg/ kg) para segunda amostra, resultados estes inferiores aos descritos pela CETESB para amostras de lodo da mesma estação de tratamento. Dada uma potencial utilização deste material como adubo agrícola, foi determinada a fração disponível destes metais. Com exceção do níquel (25%), uma fração pequena dos metais estudados encontra-se na forma assimilável pelas plantas (< 20%), com base no procedimento descrito pela EMBRAPASolos (extração com DTPA). Os efeitos de uma eventual utilização de composto húmico mineral (CHM) como aditivo ao lodo, visando uma redução na fração assimilável de metais, foi estudada em função da quantidade de CHM aplicado e do pH da solução final. Os resultados obtidos demonstraram que o CHM possui um poder de complexação para os metais semelhante ao do DTPA e que, sua aplicação ao lodo de esgoto, teria, na realidade um efeito de potencializar a fração disponível de certos metais como o zinco.
Based on the EPA-3050B procedure, the concentration of metals (Cd, Cr, Cu, Ni, Pb and Zn) in sludge source at CETESB studied. Two samples were analyzed and the results obtained were (Cd =3,4 ; Cr =367,5 ; Cu =263,0 ; Ni=290,6 ; Pb =91,5 ; Zn =1324,9 mg/ kg) and (Cd =3,0 ; Cr =332,2 ; Cu =190,5 ; Ni=274,6 ; Pb =82,5 ; Zn =1284,2 mg/ kg). These concentrations were below those descried by SABESP for sludge samples measured in the same treatment station. Due to the potential utilization of these materials as manure in agriculture, the disposal fraction of these metals was determined. Except nickel (25%), a little fraction of metals studied is assimilated by plants (< 20%), base on the procedure already descried by EMBRAPA- Solos (extraction with DTPA). The effect of an eventual utilization to humic mineral compound (HMC), as additive in sludge, aiming the reduction of the assimilated fraction of metals, were studied in function of both, the amount of HMC applied and the final pH of the solution. The results obtained showed that HMC has a complexation potential for metals similar to DTPA and that, its application in sludge, has in fact, a potential effect on the disposal fraction of metals such as zinc.

The sewage sludge is a residue of served water treatment (domestic, industrial or agoindustrial water), with organic material levels and basic macro and micronutrients for the soil fertility. This work had the aim of studying the behavior of coffee plants, comparing the sewage sludge, corral manure and mineral fertilization usage, evaluating the plants development, soil fertility alterations and plants nutritional state, as well the accumulation of heavy metal which could reach biotoxic concentrations for the soil and plants treated with the different doses of sewage sludge. The experiment had been installed in 20 liters vases filled with RED LATOSSOIL. It had been used Tupi Coffee, ancestry IAC 1669-33 as indicator plant. The experiment had been constituted of 9 treatments and 8 replications, totaling 72 plants. The biometrics parameters of plants had been evaluated in each 2 months, as plants height, cop diameter. After 12 months, the chemical compound of physiological mature leaves had been evaluated, aiming to determine N, P, Ca, Mg, S, Cu, Fe, Mn Zn, Mo and the heavy metals As, Cd, Cr, Hg, Ni, Pb and Se. In the same period, soil samples had been removed from the plots, in which 4 simple samples had been homogenized, dried in air and sifted, and later, compound samples had been removed to determine the nutrients. The averages of the characteristics had been evaluated by the variation analysis chart (ANAVA) and multiple linear regression and compared by the Tukey Test, with 5% significance level.

O presente trabalho teve por objetivo estudar as modificações de propriedades químicas e agregação de um Latossolo Vermelho de Cerrado, sob manejo com adubação orgânica e/ou mineral e com diferentes sistemas de cultivo. O experimento foi realizado na área experimental da Universidade Estadual Paulista - UNESP, localizada no município de Selvíria, MS, nos anos agrícolas 2003/04 e 2004/05. Os tratamentos constaram de três sistemas de cultivo do solo (convencional; cultivo mínimo e semeadura direta) e seis adubações (testemunha - sem adubação; adubação mineral-70 kg ha-1 de P2O5 e 80 kg ha-1 de K2O; adubação orgânica - esterco bovino-20 Mg ha-1; u adubação orgânica (esterco bovino)+ u da adubação mineral recomendada; 20 e 30 Mg ha-1 de lodo de esgoto). A agregação do solo foi modificada após 2 anos, sendo que os manejos com semeadura direta e cultivo mínimo apresentaram os melhores resultados, quanto aos adubos mineral e orgânicos, estes se destacaram em relação a testemunha. Para a massa de 100 grãos a utilização de adubos minerais e orgânicos proporcionou melhores resultados em comparação a testemunha, no entanto, para a produtividade foram semelhantes.

The present work had for objective to study the modifications of chemical properties and of the aggregation of a soil after two years of management with organic manuring and/or mineral under different preparation systems. The experiment was carried out in Selvíria, state of the Mato Grosso do Sul, Brazil, during the agricultural years of 2003/04 and 2004/05. The treatments were: Conventional-tillage, chisel tillage and no-tillage besides six manurings: control (no manuring), manuring mineral, organic manure, organic+mineral, 20 and 30 Mg ha-1 of sewage sludge. After two years of the application of the fertilizers, organic and/or mineral, an improvement was observed in the chemical properties of the soil in comparison with initial analysis. Regarding the aggregate stability of the soil, organic fertilizers and/or minerals and no-till and the minimum cultivation provided a better aggregation of the soil. To weight of 100 soybean grains there was significant difference try use of organic and mineral fertilization; however it was not observed for the production. To dry matter of sorghum the conventional preparation presented the largest values compared to the no-till and, the minimum preparation was similar the both.

Texto completoThe sustainable and high productivity plantations of eucalyptus species can contribute to the solution of the challenges regarding the wood for the several industrial sectors, as well as the environmental and social aspects in Brazil and in the world. The researches experimental have been demonstrating that the mineral and organic fertilizations (biosolids) increase the growth rate of the eucalypt trees being, however, scarce the information on the wood properties. From two field experiments installed in the Experimental Station of Itatinga-SP, evaluations were done one the growth dynamics in of trees diameter and the anatomical and physical wood properties of Eucalyptus grandis. The eucalypt trees were planted in the spacing 3x2 m and fertilized with nitrogen (planting, 6, 12, 18 months) and sewage sludge (planting, 8 months) in the Experiment A and potassium and sodium (planting, 6, 12 months) in the Experiment B. In the two experiments were selected, according with the classes of basal area, the eucalypt trees with 22 months old and installed dendrometer bands for the monitoring of the increment in trees diameter from February 2006 to January 2007. Eucalypt trees selected in classes of basal area were cut with 24 months old and wood samples were collected in different % of the total height. The anatomical and physical wood properties were analyzed, being (i) the radial variation of the fibers, vessels and the wood apparent density by of X-ray densitometry and (ii) longitudinal variation of the wood basic density. In the two experiments the effect of the climatic seasonality was detected in increment of the trees diameter, with laugher grow periods (February-May) and lower periods (July- August). Significant differences between the treatments and classes of basal area of the trees for the growth and some parameters of wood density and fibers and vessels were also detected. The model of variation of the wood apparent density was elevated near to pith and decreased/stabilizes in bark direction. The wood basic density decreased and/or it stabilized of the base until 25%; increased up to 75% and decreased up to 100% of the trees height. The radial variation was characterized by the increase of the width, lumen diameter and length and the decrease of the cell wall thickness of the fibers and for the increase of the tangential diameter and the area and reduction of the frequency of the vessels.

Texto completoA carbonatação é um fenômeno natural às estruturas de concreto, ocorrendo pela reação entre o CO2, concentrado no ambiente, e o Ca(OH)2, presente na matriz cimentícea. A reação de carbonatação provoca a redução do pH do concreto, causando a destruição da camada passivadora, que envolve a armadura de aço, deixando esta vulnerável ao processo de corrosão. Nesta pesquisa, foi investigado o desempenho, frente à carbonatação, de concretos com adição de cinzas de lodo de estação de tratamento de água, nos teores de 5%, 10%, 15%, 20%, 25% e 30% em substituição ao cimento Portland, bem como uma mistura de referência, sem adições minerais. Todas as misturas foram moldadas com três relações a/agl (0,35; 0,50 e 0,65) e com dois períodos de cura úmida (três e sete dias). Os corpos-de-prova de concreto foram submetidos à um pré-condicionamento, conforme procedimentos sugeridos pela norma RILEM TC 116-PCD, visando o equilíbrio de umidade (75% ± 2%) em um ambiente aéreo com temperatura constante (23°C ± 2°C) e distribuição uniforme de umidade. Posteriormente os corpos-de-prova foram encaminhados para uma câmara de carbonatação, com umidade (75% ± 2%), temperatura (23°C ± 2°C) e concentração de CO2 (3%) devidamente reguladas. Os corpos-de-prova foram ensaiados após 4, 8, 12 e 16 semanas de exposição ao CO2, por meio de aspersão de fenolftaleína, sendo obtidas as profundidades de carbonatação e, com isso, os coeficientes de carbonatação. Os resultados demonstraram que a incorporação de cinzas de lodo de estação de tratamento de água ao concreto acarreta no aumento da carbonatação nos mesmos, para todas as misturas investigadas. Comparações com resultados de Porosimetria por Intrusão de Mercúrio e Termogravimetria permitiram atribuir este efeito às alterações microestruturais e a diminuição da reserva alcalina das misturas com adição de cinzas de lodo. Através de uma análise em igualdade de resistência, constatou-se que os concretos com adição de cinzas de lodo de estação de tratamento de água são viáveis, do ponto de vista da vida útil frente à carbonatação, apenas para níveis de resistência mecânica mais altos.

Texto completoThe sewage sludge (SS) applied in planted forest soils, based on the nitrogen criterion, may increase the production of wood without causing damage to the forest environment. However, there is a need for research to evaluate the use of nutrients contained in the SS and to recommend appropriate management regarding for its application on soil using mineral fertilizer supplements by aspects of productivity and economic. The objective were to analyze the effect of combinations of sewage sludge doses and nitrogen and phosphate mineral fertilizer on the production on dry matter content and wood production of Eucalyptus grandis at 95 months after planting, and to evaluate the economic viability of SS recommendation and its complementation with nitrogen and phosphate mineral fertilizer for the forest producer. The experiment was installed in a commercial area of Suzano, in Angatuba-SP, sludge doses are applying (0, 7.7, 15.4 and 23.1 Mg ha-1, dry base), and nitrogen mineral fertilizer (0; 46.9; 95.1 and 142 kg ha-1), phosphate (0, 27.7, 55.9 and 84 kg -1 P2O5), and potassium (175 kg ha-1 K2O for all treatments, due to the low content of this nutrient in SS); in a randomized block design in a factorial 4x4x4. For the specific purpose of this study, combinations were taken in doses of N and P and among all these SS doses were studied. The production of dry matter and wood, calculated by equation Smalian were determined from measurements collected at 95 months post-planting eucalyptus. The revenue and cost values were raised in the reference year 2013. For the evaluation of the economic viability, we used the method of annualized net present value (ANPV), considering 6 and 12% per year discount rates and that the forest producer would bear 0 or 100% of the cost of transport of sewage sludge. There was a linear effect of SS doses on the production of dry biomass of wood, bark, leaf and branches and wood volume. The dose of 23.1 Mg ha-1 SS, equivalent to 150% of SS dose recommended by the criterion nitrogen, provided the highest total dry matter, 187 Mg ha-1, and wood+bark of 173 Mg ha-1 and stem volume of 529 m3 ha-1, with average annual increment of 66 m3 ha-1 yr -1. When considering the criterion to the application of SS, based on N, and the forestry producer has borne all the shipping cost of this waste, it was observed that the highest economic return treatment was that using a dose of 15.4 Mg ha- 1 SS and 84 kg ha-1 P2O5 to 6% per year discount rate; and one that applied 7.7 Mg ha-1 SS and 28 kg ha-1 P2O5 to the interest discount rate to 12% per year rate. When the forest producer was exempted to pay the SS shipping cost, the most economically viable treatment was what used 15.4 Mg ha-1 doses of SS and 84 kg ha-1 P2O5 to 6 and 12% per year discount rates
