Abstract:

ZusammenfassungAnhand von Alexander Mitscherlichs Plädoyers für eine Psychosomatische Medizin werden dessen epistemologische Neupositionierungen in den 1940er, 1950er und 1960er Jahren untersucht. Sie eröffnen den Blick auf die Auseinandersetzung von Psychiatern, Internisten und Psychotherapeuten um valides und handlungsrelevantes Wissen in der Nachkriegszeit. Zentral war für Mitscherlich ein Krankheitsverständnis, das der Subjektivität der Patienten einen festen Platz zuwies. Damit verbunden war eine kontinuierliche Kritik an statistischen Verfahren zur Validierung von Einzelbefunden und Hypothesen. Gezeigt wird, wie anpassungsfähig Mitscherlich mit seiner Kritik an einer naturwissenschaftlich orientierten Methodik in der Medizin war, wenngleich er die ursprüngliche Stoßrichtung trotz aller Wandlungen aufrechterhielt.

Abstract:

Hannah Arendt and Alexander and Margarete Mitscherlich produced influential accounts of the postwar West-German population's silence or inarticuleteness. The Mitscherlichs claimed that this silence was symptomatic of a blocked process of mourning; Arendt saw it as a legacy of brutal totalitarian rule. However, both viewed the rapid economic recovery as evidence of the German inability to engage in discursively mediated therapeutic and political processes. Frantic busyness was a form of silence. This paper presents a critical reassessment of these approaches. By drawing on Albert Hirschman's theory of exit and voice, it argues that economic activity possesses a communicative dimension. The alleged retreat from politics is not a symptom of muteness but rather indicates people's preference for an alternative mode of communication. Arendt and the Mitscherlich may be right in assuming a correlation between the postwar economic recovery and ostensible political apathy, but lack the conceptual means to clarify the relationship.

Abstract:

A nonlinear Mitscherlich function was found to be superior to quadratic and square root functions in estimating yield response to nitrogen based on a Finnish sample of barley. Nonnested hypothesis testing (J-test) indicated the Mitscherlich functional form to fit the data better than the quadratic form based on this sample. In the analysis of the crop response for spring wheat the Mitscherlich functional form could not be proved superior by a J-test. The inferred profit maximizing nitrogen fertilization levels based on the Mitscherlich functional form exceeded the quadratic polynomial forms and were lower than the inferred levels using square root specifications. Implementing 100% nitrogen price increases or 50% producer price reductions lowered the profit maximizing nitrogen application doses by 20-24%, according to the Mitscherlich specification.

Abstract:

Two models are proposed to describe atypical biphasic gas production profiles obtained from in vitro digestibility studies. The models are extensions of the standard Mitscherlich equation, comprising either two Mitscherlich terms or one Mitscherlich and one linear term. Two models that describe typical monophasic gas production curves, the standard Mitscherlich and the France model [a generalised Mitscherlich (root-t) equation], were assessed for comparison. Models were fitted to 25 gas production profiles resulting from incubating feedstuffs with faecal inocula from equines. Seventeen profiles displayed atypical biphasic patterns while the other eight displayed typical monophasic patterns. Models were evaluated using statistical measures of goodness-of-fit and by analysis of residuals. Good agreement was found between observed atypical profiles values and fitted values obtained with the two biphasic models, and both can revert to a simple Mitscherlich allowing them to describe typical monophasic profiles. The models contain kinetic fermentation parameters that can be used in conjunction with substrate degradability information and digesta passage rate to calculate extent of substrate degradation in the rumen or hindgut. Thus, models link the in vitro gas production technique to nutrient supply in the animal by providing information relating to digestion and nutritive value of feedstuffs.

Abstract:

German post-war psychoanalysis was marked for many years by a strong narrative that assured its professional identity: psychoanalysis in Germany had been liquidated by National Socialism and had been rebuilt from scratch after 1945. The psychoanalyst Alexander Mitscherlich was both an integral part of this narrative and its most important propagator. The author analyses the genesis of this narrative, its moral and political function and finally its demise. In doing so he gives a short account of the first years of the reconstruction of psychoanalytic life in Germany after 1945. He draws on new research on Alexander Mitscherlich to describe his relationship with organized psychoanalysis. He explains why the biography of Mitscherlich and the history of German post-war analysis became interrelated to the point where both provided an integral part of each other's self-understanding. Finally, he documents how the narrative was gradually deconstructed after the death of Mitscherlich in 1982.

Abstract:

An evaluation of general models that describe gas production profiles is presented. The models are derived from first principles by considering a simple three-pool scheme and permit the extent of ruminal degradation to be calculated, as described in the companion paper. The models evaluated were the generalized Mitscherlich, simple Mitscherlich, generalized Michaelis–Menten, simple Michaelis–Menten, Gompertz, and logistic. Five sets of gas production data consisting of 216 curves, obtained using a wide range of feeds (including straw, hay, silage, grain and various byproducts), were analysed to study the performance of these gas production models. Application of the non-sigmoidal models (simple Mitscherlich and Michaelis–Menten) to the data resulted in convergence problems and these models were found to be inadequate in many cases. Based on results of a pairwise comparison between models (variance ratio test), ranking of residual mean squares, lack-of-fit test, and of analyses of residuals, the generalized Mitscherlich and the generalized Michaelis–Menten models seemed particularly suited because of their flexibility to encompass sigmoidal and non-sigmoidal shapes of gas production profiles, whether symmetrical or not.

Abstract:

Abstract. The aim of this study was to show how to adapt and convert the Mitscherlich model to animal nutrition studies in a theoretical way. The new form of the model was obtained by applying a mathematical conversion step by step to use the Mitscherlich model in an in vitro gas production or in in situ nylon bag studies which have an important role in animal nutrition. The parameter which is not included in new model but important for digestion was gained for the model. Moreover, it was shown how to obtain important digestion equations by using the new form of Mitscherlich model. Also the equation formulas were obtained for both with and without lag-phase. Consequently, it was shown how to convert a model, which is previously not used in terms of animal nutrition, into a different purposive form and how to obtain the new equations from this form step by step in a theoretical way. Besides, the new form of Mitscherlich model, which is an alternative to other models, will importantly contribute to the literature by obtaining some important equations not found in many of the other models.

Full text

Abstract:

Summary. This paper examines the response of total annual dry matter production of pastures to a range of rates of phosphate application supplied in fertilisers from various sources. Data from the National Reactive Phosphate Rock Project were used to compare the goodness-of-fit of 2 non-linear regression models, the Mitscherlich and rational functions models, both of which are convex curves lacking an inflection point. These models were fitted to the data from the 2 ‘core experiments’ and tended to give closely equivalent results, with the Mitscherlich model fitting somewhat better in two-thirds of the cases. Generally, both models fitted the data well, with a test for ‘lack of fit’ being non-significant. The models proved capable of fitting all the various responses observed in the 2 experiments, including: (i) the ‘classic’ asymptotic regression response where dry matter production rises gradually with decreasing slope from a baseline at zero added phosphorus to approach an asymptote at very high rates of phosphate application; (ii) a very rapid rise at a low phosphate rate to an almost constant response value with increasing phosphate application; and (iii) an almost linear growth rate with non-zero slope throughout the phosphate application rate range. The Mitscherlich model was generally more stable for the less classical responses, and its parameters were consistently easy to interpret. Hence, the Mitscherlich model is recommended as suitable for describing pasture yield as a function of phosphate application. A new measure of relative fertiliser performance is proposed, based upon the area below the curved line defined by the fitted Mitscherlich curve, which is simultaneously above the horizontal straight line representing the baseline of no added phosphate. The ratio of this area calculated for a test fertiliser to the similarly defined area calculated for a soluble reference fertiliser such as superphosphate serves as a relative performance index. Also, when the area calculated for the reference fertiliser is less than 10% of the total area under the fitted curve, the site is considered to be unresponsive to phosphate addition.

Abstract:

Gas production profiles typically show a monotonically increasing monophasic pattern. However, atypical gas production profiles exist whereby at least two consecutive phases of gas production or additional extraneous features that distort the typical profile are present. Such profiles are more likely to occur with the use of a fecal inoculum and are much less well described. The presence of multiple phases or non-descript extraneous features makes it difficult to apply directly recommended modeling approaches such as standard response functions or classical growth functions. To overcome such difficulties, extensions of the Mitscherlich equation and a numerical modeling option also based on the Mitscherlich are explored. The numerical modeling option uses an estimate of relative rate obtained from the smoothed data profile and an estimate of maximum gas produced together with any lag time information drawn from the raw data to construct a simple Mitscherlich equation. In summary, this article illustrates the analysis of atypical gas production profiles obtained using a fecal inoculum and explores the methodology of numerical modeling to reconstruct equivalent typical growth-like trends.

Full text

Abstract:

The article presents a brief analysis of the main pro-visions of the “law on the cumulative influence of growth factors", proposed by a major theorist and experimenter of the agronomic science, Professor E.A. Mitscherlich (1909). The method of E.A. Mitscherlich has been used so far and is still widely used in the different countries for mathematical processing (evaluation) of the results of laboratory, plotting and field experiments on the effect of various types and amounts of fertilizers on different plants, determining the content of nutrients in the soil and the need for fertilizer in the soil, and studying the dissolution, and adsorption of fertilizers in the soil, determination of the specific surface area, and soil structure during irrigation, etc. The method of E.A. Mitscherlich made it possible to determine the maximum possible yield of the different agricultural crops and to find possible reserves of nutrients in different soils, for different conditions, in many cases (more than 30,000 field experiments). Calculations using the method of E.A. Mitscherlich led to a good match of experimental and calculated data. The article proposes a new method for assessing the effect of crop yield and yield factors based on the following statement: yield and yield growth increase with an increase in the amount of growth factor and are proportional to the amount of the crop that has not reached the (maximum) limit value and the possible value of the crop, above a certain minimum (initial) value. For practical purposes, in the article, approximate formulas are obtained that allow us finding the value of the coefficient of action of growth factors on yield, the amount of nutrients in the soil, and the functional dependence of the crop yield under the action of specific growth fac-tors. The proposed mathematical model of the effect of growth factors on the yield (productivity) of agricultural crops is more general than the well-known law of the effect of growth factors on productivity proposed by E.A. Mitscherlich. The article considers examples of calculations that show a good match between the experimental and calculated data.

Abstract:

SUMMARYThe lactation curve may be represented mathematically by the general equation Y = Aϕ1(t)ϕ2(t), where A is a positive scalar, ϕ1,(t) is a positive monotonically increasing function with an asymptote at ϕ1 = 1, and ϕ2 is a monotonically decreasing function with an initial value of unity and an asymptote at ϕ2 = 0. Functions considered as candidates for ϕ1 were: (Mitscherlich), (Michaelis-Menten), (generalized saturation kinetic), 1/(1 + b0 (logistic), b0 exp (Gompertz) and [1+ tanh(b0 + b1t)]/2 (hyperbolic tangent). Candidates for ϕ2 were e–ct (exponential) and 1/(1 + ct) (inverse straight line). The 12 models thus obtained and Y = Atb e–ct (Wood's model) were fitted to whole-lactation data from 23 animals. Mitscherlich x exponential, Michaelis-Menten x exponential, logistic x exponential, logistic × inverse straight line and Wood's model all fitted well. For these models, expressions for time to peak, maximum yield, total yield over a finite lactation and relative decline at the midway point of the declining phase were obtained. The Mitscherlich x exponential model generally fitted better than Wood's model and, unlike Wood's model, gives simple algebraic formulae for all these summary statistics.

RESUMO O objetivo deste estudo foi descrever o crescimento de ovinos Santa Inês utilizando modelos não-lineares selecionados por análise multivariada. Dezessete modelos não-lineares foram utilizados para descrever o crescimento de cordeiros do nascimento aos 210 dias de idade. Os modelos foram classificados por meio de análise multivariada utilizando o coeficiente de determinação ajustado, critério de informação de Akaike, critério de informação Bayesiano, erro quadrático médio de predição, coeficiente de determinação de predição, desvio médio absoluto dos resíduos e percentual de convergência como avaliadores da qualidade do ajuste. Os modelos Richards, Reynolds e Weibull não convergiram e os modelos Schnute, Meloun II, IV e VI, Gamito, Michaelis Menten e Michaelis Menten Modificado não apresentaram padrão de crescimento tradicional. Os modelos Mitscherlich, Gompertz, Logístico, Meloun I, III e V, Brody e Von Bertalanffy convergiram e foram utilizados na análise de agrupamento. Dentre os quatroclusters formados, o primeiro, composto pelos modelos Mitscherlich, Meloun I e Brody, apresentou os melhores valores para os critério de informação de Akaike e bayesiano. Os parâmetros da curva foram influenciados pelo sexo e o tipo de parto (P<0,05) e o ponto inflexão ocorreu aos 94 dias de idade. Os modelos Mitscherlich, Meloun I e Brody são adequados e equivalentes para descrição do crescimento de ovinos Santa Inês.

Abstract:

The parameters of yield response functions can vary by year. Past studies usually assume yield functions are nonstochastic or “limited” stochastic. In this study, we estimate rye–ryegrass yield functions in which all parameters are random. The three functional forms considered are the linear response plateau, the quadratic, and the Spillman-Mitscherlich. Nonstochastic yield models are rejected in favor of stochastic parameter models. Quadratic functional forms fit the data poorly. Optimal nitrogen application recommendations are calculated for the linear response plateau and Spillman-Mitscherlich. The stochastic models lead to smaller recommended levels of nitrogen, but the economic benefits of using fully stochastic crop yield functions are small because expected profit functions are relatively flat for the stochastic yield functions. Stochastic crop yield functions provide a way of incorporating production, uncertainty into input decisions.

Abstract:

The grain yield response of maize (Zea mays) to various rates of applied phosphorus (P) was measured at each of 17 sites in the South Burnett region of south-eastern Queensland. The soils at all sites were Ferrosols. Relative grain yield of the nil applied P treatment [100 × (yield at nil applied P/maximum yield)] was related to Colwell (0·5 M NaHCO3) extractable P (PB), CaCl2-extractable P, and equilibrium P concentration and P buffer capacity calculated from P sorption curves. Of these P measurements, PB was most highly correlated with relative grain yield (R2 = 0·94 for a linear response and plateau fit, R2 = 0·92 for a Mitscherlich fit), and the PB values at 90% maximum grain yield were 20 mg/kg for the linear response and plateau model and 32 mg/kg for the Mitscherlich equation.

Abstract:

Summarizing the activities of the Sigmund-Freud-Institute (SFI) in Frankfurt am Main in 1969, its director Alexander Mitscherlich painted a bleak picture of recent events. Psychoanalysis had always faced opposition in Germany, he wrote, but of late Freudianism contended with several broadsides simultaneously: critics still maintained that it placed too much emphasis on sexuality; some added that behavioral therapy or sophisticated medication did a better job at treating patients than long-term analysis; yet others argued that Freud's teachings may have been relevant in 1900, but that society no longer resembled turn-of-the-twentieth-century Vienna. On top of all this, Mitscherlich complained, a new generation demanded that psychoanalysis figure as chief witness for an antiauthoritarian education that emphasized indulgence rather than sublimation. “Society” continued to make life difficult for psychoanalysis, then, and it was for this reason that the government needed to assist the SFI in its efforts to train a new generation of analysts in Germany.

Abstract:

Raya (Brassica juncea L.) as an imperative oilseed crop, necessitates a judicious amount of fertilizers for its sufficient yield, however the soils in Pakistan are becoming nutrient scarce owing to extensive farming. In order to evaluate the accurate fertilizer requirement for potential raya yields, an experiment was conducted at Regional agricultural research institute, Bahawalpur, Pakistan during the years 2018-2020. Various combinations of NPK fertilizers were made and applied to Raya crop. The treatments were T1 (0-0-0 NPK kg/ha), T2 (0-60-60 NPK kg/ha) ,T3 (60-60-60 NPK kg/ha), T4 (90-60-60 NPK kg/ha), T5 (120-60-60 NPK kg/ha), T6 (90-0-60 NPK kg/ha), T7 (90-30-60 NPK kg/ha), T8 (90-90-60 NPK kg/ha),T9 (90-60-0 NPK kg/ha), T10 (90-60-30 NPK kg/ha) and T11 (90-60-90 NPK kg/ha). Subsequently, fertilizer recommendations were made on the basis of Mitscherlich-Bray equation. Theoretical maximum yield of Raya was obtained by plotting log y (grain yield) versus 1/x (amount of nutrient applied). The results showed that Soil have 10 kg (P ha?1) would need 125 kg Phosphorus oxide per hectare fertilizer to attain 90% grain yield. Moreover it was concluded that recommended dose of fertilizer for Raya was less in comparison to that achieved through application of Mitscherlich-Bray equation. From these results, it is crucial to assess the 90%maximum yield by implementing the formula prior to conducting of field trials in order to enhance economic outputs and to balance the nutrients in soils.

Full text

Abstract:

The dry matter production (DM) and seed yield of subterranean clover (Trifolium subterraneum L. cv. Daliak) were reduced by infestations of redlegged earth mite (Halotydeus destructor Tucker) and blue-green aphid (Acyrthosiphon kondoi Shinji) during spring growth, flowering and burr burial. The dominance of these pests varied with season. The effects of spraying with insecticides on the DM and seed yield responses to superphosphate and potassium chloride fertilisers were measured. Responses to superphosphate were described by Mitscherlich functions for each of 3 levels of potassium chloride, except for seed yields with pest sprays. At optimum levels of superphosphate and potassium chloride, controlling pests increased DM by up to 150% (from 4.37 to 6.52 t/ha). For all levels of superphosphate, spraying to control pests where no potassium chloride was applied significantly increased DM over that on unsprayed plots that were fertilised with potassium chloride. The maximum DM response to superphosphate application was achieved at 15-20 kg P/ha. With optimum superphosphate, the value for DM depended on the combination of spraying for pests and amount of potassium chloride applied, generating a series of Mitscherlich response curves for superphosphate application with differing maximum yields. With optimum superphosphate applied, the least DM recorded within a season was 3.47 t/ha (pests not sprayed, nil potassium chloride), and the most was 6.52 t/ha (pests sprayed, 120 kg potassium chloride/ha), an increase of about 180%. At optimum levels of superphosphate and potassium chloride, controlling pests increased seed yield by up to 380% (from 290 to 1100 kg/ha). With optimum superphosphate, seed yield within a season ranged from 210 (pests not sprayed, nil potassium chloride) to 1100 kg/ha (pests sprayed, 120 kg potassium chloride/ha), an increase of 524%. With pests sprayed, seed yield declined with superphosphate applications >20 kg P/ha; the relationship was best described by a quadratic function. With pests not sprayed, seed yield did not decline with increasing amounts of superphosphate, and the relationship fitted a Mitscherlich function.

Abstract:

The phosphorus (P) requirements of crisphead lettuce (Lactuca sativa L. cv. Oxley) was measured over 2 consecutive winter plantings using superphosphate that was freshly applied and applied 9 months before planting, at 0-600 kg/ha on a newly cleared Karrakatta sand of low natural P fertility. There was a significant (P<0.001) head yield response to level of applied P in both years. Phosphorus uptake by whole plants and plant shoots was related to level of applied P in Mitscherlich relationships (R2 = 0.88). Phosphorus recovery efficiency (fertiliser P uptake by shoots/P applied, both in kg/ha) by shoots decreased from 0.16 at 50 to 0.04 at 600 kg applied P/ha. Phosphorus recovery efficiency by whole plants (shoots plus roots) decreased from 0.18 at 50 to 0.05 at 600 kg P/ha. The level of freshly applied P required for either 95 or 99% of maximum relative yield over the 2 years (maximum yield, 86 t/ha) was 276 and 427 kg P/ha (Mitscherlich relationship, R2 = 0.95), respectively at <10 �g/g soil test P (newly cleared sites). The marketable yield was 82 and 95% of total yield at 276 and 427 kg P/ha respectively. Bicarbonate-soluble P extracted from the top 15 cm of soil was determined on residual P sites over 2 years where P was applied at 0-600 kg/ha. These soil test levels were related to head yield in a Mitscherlich relationship (R2 = 0.88). The critical soil test P values required for either 95 or 99% of maximum relative yield, over the 2 years, were 80 and 115 �g/g, respectively. Phosphorus in the wrapper leaf at early heading required for 95 or 99% of maximum yield was 0.59 � 0.03 and 0.61 � 0.03% (spline regression, R2 = 0.80), respectively. Soil and plant testing could be used to assist in reducing fertiliser costs, improving utilisation of freshly- and previously-applied fertiliser P by lettuce and reducing P losses to water systems on the Swan Coastal Plain in Western Australia.

Abstract:

Field experiments with rain-fed Bragg soybeans (Glycine max) were carried out at 30 sites in central south-eastern Queensland over six years. The sites covered a wide range of soil types and P buffer capacities. Several rates of P fertilizer were band-applied in 0.9 m rows at planting. Relative grain yield at each site was correlated with 0.5 M NaHC03 extractable (PB) and 0.01 M CaCl2 extractable (PC) phosphorus. Mitscherlich equations of best fit indicated that PC was better correlated (r2 = 0.85) with relative grain yield than PB (r2 = 0.59). At 90% maximum grain yield, the 'critical' PC value was 43 �g P kg-1. The Mitscherlich curvature coefficient, c, was correlated (r2 = 0.49, P < 0.001) with the amount of P fertilizer required for 90% maximum grain yield, but not with soil P buffer capacity, as measured by a single point sorption index (r2 = 0.06). Factors other than the P sorbing ability of the soil were affecting the curvature coefficient, but could not be identified in this work. PC was sufficiently well correlated (r2 = 0.66, P < 0.001) with P fertilizer requirements to have use as a predictor of these requirements. The findings are compared with those obtained for other crops and P fertilizer application methods.

As pesagens ocorreram ao nascimento e em intervalos de 90 dias até dois anos de idade. Para análise dos dados de peso-idade, foram utilizados os seguintes modelos não-lineares: Brody, Gompertz, Logístico, Mitscherlich, von Bertalanffy, Richards e Logístico duplo. As fontes de variação estudadas no modelo misto foram sexo, propriedade, ano e mês de nascimento, tipo de sistema de criação e interação sexo*sistema de criação, como efeitos fixos, e reprodutor e mãe, como efeitos aleatórios. A equação Logística Dupla foi a que apresentou o melhor ajustamento e a Mitscherlich, o pior, segundo o número de convergências e o índice de ajuste. Os efeitos fixos mais influentes foram sexo, propriedade, ano e mês de nascimento e sistema de criação. O efeito aleatório mais influente foi o de mãe. A variabilidade encontrada pode possibilitar a exploração da modificação da curva de crescimento por meio de programas de melhoramento genético.

Abstract:

Twenty-three virgin Western Australian soils of different buffer capacities (BC) for phosphorus (P) were collected. The effects of BC on the relationships between Colwell soil test P and the level of P applied, yield and soil test P, and yield and the level of P applied were studied. Wheat (Triticum aestivum cv. Reeves), grown for 27 days in a glasshouse, was used. Two methods of measuring P sorption of soils, P buffer capacity (PBC) and P retention index (PRI), were used. The PBC is determined from a multi-point sorption curve. The PRI is a new, diagnostic, one-point, sorption method now widely used for commercial soil P testing in Western Australia. Both PBC and PRI produced similar results. The relationship between soil test P and the level of P applied was adequately described by a linear equation. When the slope coefficient of the linear equations was related to PBC or PRI, there was no relationship. The other two relationships were adequately described by a Mitscherlich equation. When the curvature coefficient of the Mitscherlich equation was related to PBC or PRI, the trend was for the value of the coefficient to decrease with increasing PBC or PRI. Consequently, as the capacity of the soil to sorb P increased the trend was for larger soil test P or higher levels of P application to produce the same yield.

Abstract:

Summary. The phosphorus (P) requirements of crisphead lettuce (Lactuca sativa L. cv. Salinas) were measured over 2 consecutive spring plantings using superphosphate that was freshly applied and applied 9 months before planting, at 0–600 kg P/ha on a newly-cleared Karrakatta sand of low natural P fertility. The response of lettuce to placement of phosphate fertiliser (banded, broadcast) was also investigated. There was a significant (P<0.001) head yield response to level of applied P in all experiments. There was no significant effect of placement on yield even though the concentrations of P in the wrapper leaves were on average 12% higher in the broadcast treatment. A Mitscherlich function described the relationship of P uptake by whole plants and plant shoots to level of applied P. Recovery efficiency of P fertiliser (fertiliser P uptake by shoots/P applied, both in kg/ha) by shoots decreased from 0.12 at 50 to 0.05 at 600 kg applied P/ha. Phosphorus recovery efficiency by whole plants (shoots plus roots) decreased from 0.13 at 50 to 0.05 at 600 kg P/ha. The level of freshly-applied P required for 95 and 99% of maximum relative yield over the 2 years (maximum yield, 89–112 t/ha) was 185 and 286 kg P/ha (Mitscherlich relationship, R2 = 0.93), respectively, at <10 µg/g soil test P (newly-cleared sites). The marketable yield was 82 and 92% of total yield at 185 and 286 kg P/ha respectively. Bicarbonate-soluble P extracted from the top 15 cm of soil was determined on residual P sites over 2 years where P was applied at 0–600 kg/ha. These soil test levels were related to head yield in a Mitscherlich relationship (R2 = 0.90). The critical soil test P values required for 95 and 99% of maximum relative yield, over the 2 years, were 81 and 121 µg/g respectively. Phosphorus in the wrapper leaf at early heading required for 95 and 99% of maximum yield was 0.40 ± 0.02 and 0.42 ± 0.02% (spline regression, R2 = 0.81), respectively. Soil and plant testing could be used to assist in reducing fertiliser costs, improving the efficiency of use of freshly- and previously-applied fertiliser P by lettuce and reducing P losses to water systems on the Swan Coastal Plain in Western Australia. Changing placement from broadcasting to banding will not improve efficiency of phosphate fertiliser use by lettuce on Karrakatta sands.

A Cox nonnested test is conducted using a fast double bootstrap (FDB) method to select among three competing functional forms (linear response plateau, quadratic, and Mitscherlich-Baule) to model forage yield response to nitrogen applied with swine effluent. The quadratic is rejected in favor of one of the other functional forms in all cases. The FDB p values differed slightly from the single bootstrap p values. Buffalograss was slightly more profitable than bermudagrass and has the ability to use almost as much nitrogen as bermudagrass.

Abstract:

Avaliaram-se diferentes modelos lineares (quadrático, linear-platô, quadrático-platô e raiz quadrada) e não lineares (exponencial-Mitscherlich e Michaelis-Menten) para descrever o crescimento microbiano ruminal em função do suprimento de nutrientes. Utilizou-se banco de dados compostos por 76 observações de meios de cultivo ruminal in vitro (mix de bactéria) contendo 0,0; 0,375; 0,75; 1,50; 3,0; 6,0; 12 e 24g de sacarose/L. O crescimento microbiano foi avaliado por meio de mensuração da densidade óptica (OD - 600nm) após 0; 6; 12; 18 e 24 horas de fermentação. A avaliação conjunta dos parâmetros da regressão linear dos valores preditos e observados indicou adequação de todos os modelos na predição do crescimento microbiano. A partição do quadrado médio do erro de predição não permitiu identificar diferenças na qualidade da predição do crescimento microbiano entre os modelos. Porém, ao avaliar o crescimento marginal em função do suprimento de glicose verificou-se inadequação do modelo linear-platô e do modelo quadrático (em baixos níveis substratos). Os modelos quadrático-platô, raiz quadrada, Mitscherlich ou Michaelis-Menten podem ser utilizados para descrever o comportamento do crescimento microbiano ruminal ao suprimento de nutrientes. Entretanto, diferenças são observadas quanto às estimativas das eficiências de uso nos diferentes níveis de substratos, o que implica em diferenças nas recomendações dos níveis ótimos de nutrientes. Neste sentido, a escolha desses modelos poderá ser modulada pelo nível de suprimento de nutrientes desejado.
