“…The micronutrient (zinc and iron) content in the soil decreased significantly after the wheat harvest with increasing P levels ( Table 8). The decrease in the post-harvest availability of Zn can be attributed to the phenomenon of P/Zn antagonism, as reported by Haldar and Mandal (1981) and Davis and Rhoads (1994). As the soil was alkaline (pH 7.8), the precipitation of Zn as Zn(OH) 2 or ZnCO 3 would have occurred, besides the formation of insoluble Zn 3 (PO 4 ) 2 compounds (Brown et al, 1960).…”

A field experiment using various levels of phosphorus, farmyard manure (FYM) and biofertilizers was undertaken at Udaipur during 2001-02 and 2002-03 to observe the direct effect of the treatments on the yield and micronutrient uptake of soybean and their residual effect on the yield and micronutrient utilization of a subsequent wheat crop. The results revealed that the seed/grain yield of soybean and wheat significantly increased with the application of increasing levels of P, FYM and biofertilizers. The integrated use of P, FYM and biofertilizers was able to replace 20 kg P 2 O 5 ha -1 to soybean and 10 kg P 2 O 5 ha -1 to wheat. The application of increasing levels of P, FYM and biofertilizers significantly enhanced the uptake of Zn, Cu, Mn and Fe by soybean and wheat. Among the biofertilizers, dual inoculation with phosphate-solubilising bacteria (PSB) + vesicular arbuscular mycorrhiza (VAM) gave the best performance. The integrated use of P levels and biofertilizers significantly improved the Zn and Fe uptake of soybean. The highest Zn and Fe uptake (125.77 mg kg -1 and 562.03 mg kg -1 , respectively) was recorded with the combined use of 40 kg P 2 O 5 ha -1 + dual inoculation. The application of FYM and P levels resulted in a significant improvement in the organic carbon, CEC, available N and P, porosity and hydraulic conductivity of the soil after the wheat harvest. Among the biofertilizers, dual inoculation led to maximum soil-available P. Phosphorus application gave a significant decrease in the DTPA-extractable Zn and Fe content of the soil after the harvest of wheat. FYM application significantly enhanced the DTPA-extractable Zn, Cu, Mn and Fe contents of the soil.

“…Haldar and Mandal [40] reported that high pH increases the solution of phosphorous, which in turn decreased the concentrations of zinc, copper, and manganese in soybean. Therefore, the pH of 6.0 may cause lower zinc contents in soil type I and result in the reduction of sweet sorghum productivity of stems and sugar contents and ethanol yields than those of soils type II and III.…”

Abstract:The use of biofuels helps to reduce the dependency on fossil fuels and therefore decreases CO2 emission. Ethanol mixed with gasoline in mandatory percentages has been used in many countries. However, production of ethanol mainly depends on food crops, commonly associated with problems such as governmental policies and social controversies. Sweet sorghum (Sorghum bicolor (L.) Moench) is one of the most potential and appropriate alternative crops for biofuel production because of its high biomass and sugar content, strong tolerance to environmental stress conditions and diseases, and wide adaptability to various soils and climates. The aim of this study was to select prospective varieties of sweet sorghum, optimum sowing times and densities to achieve high yields of ethanol production and to establish stable operational conditions in cultivating this crop. The summer-autumn cropping season combined with the sowing densities of 8.3-10.9 plant m −2

“…Estudando o efeito do P e do Zn sobre o crescimento e a nutrição de arroz em casa de vegetação, Haldar & Mandal (1981) constataram que as aplicações de P e Zn aumentaram significativamente a produção de matéria seca da parte aérea e das raízes. As doses de 50 e 100 mg dm -3 de P causaram, porém, um decréscimo na concentração de Zn, tanto na parte aérea quanto nas raízes.…”

RESUMOA aplicação de P no solo pode afetar a disponibilidade de Zn para as plantas, dependendo de sua localização. Com o objetivo de avaliar a resposta de milho à adição de Zn no solo e determinar seu nível crítico no solo e na planta, em relação à localização de P, em amostras de dois solos de Minas Gerais, realizou-se um ensaio em casa de vegetação. O experimento consistiu em um arranjo fatorial (2 x 3 x 6), correspondendo a dois solos (Latossolo Vermelho Amarelo variação Una e Argissolo Vermelho Amarelo, doravante denominados LU e PVA, respectivamente); três modos de localização de P (5, 10 e 30% do volume total do solo na dose de 200 mg dm -3 ) e seis doses de Zn (0, 1, 2, 4, 6 e 8 mg dm -3 ). Determinaramse a produção de matéria seca e os teores de Zn na parte aérea das plantas de milho. A adição de Zn aumentou linearmente (p < 0,01) o teor do elemento no solo e a absorção pela planta. No solo LU os níveis críticos variaram de 0,91 a 2,13 mg dm -3 de Zn pelo extrator Mehlich-1 e, na planta, de 18,0 a 24,6 mg kg -1 . Esses níveis foram maiores quando as aplicações de P foram localizadas em menor volume de solo. A localização de P afetou o teor de Zn na Planta. No solo LU, quando o P foi localizado no menor volume de solo e na ausência de Zn, as plantas de milho apresentaram elevados teores de P.Palavras-chave: nível crítico de Zn, forma de aplicação de P, interação Zn/P Availability of zinc to corn in response to liming and added phosphorus placement in soil ABSTRACT The soil P application can affect Zn availability to plants, depending on the application. The objective of this study was to evaluate corn (Zea mays L.) response to zinc (Zn) addition to the soil and to determine its critical level in the soil and in the plant, in relation to added phosphorus (P) placement, using two soil samples from Minas Gerais, Brazil, in a greenhouse experiment. The experiment was conducted in a factorial arrangement (2 x 3 x 6), with two soils [Red Yellow Latosol of the Una Variation (Oxisol) and RedYellow Podzolic (Ultisol), named LU and PVA, respectively]; three forms of added P placement (5, 10 and 30% of the total volume of soil in a dosage of 200 mg dm -3 ), and six Zn dosages (0, 1, 2, 4, 6 and 8 mg dm -3 ). The dry matter production and the contents of Zn in the aerial part of the corn plants were determined. The addition of Zn linearly increased (p < 0.01) its content in the soil and plant uptake. The critical levels for the LU soil ranged from 0.91 to 2.13 mg dm -3 of Zn as determined by the Mehlich-1 extractor and plant levels ranged from 18.0 to 24.6 mg kg -1 . These levels were higher when P was placed in smaller soil volumes. P placement affected the Zn content in the plant. In LU soil, when P was placed at the smallest soil volume and Zn privation, the corn plants presented elevated P levels.
