“…Sulphate is a readily soluble anion, which follows soil water movements. Significant amounts of adsorbed sulphate are found only in clay and sesquioxide rich soil horizons with pHϽ5, which is far below the usual pH of northern European agricultural soils (see Table 1) (27,28,29,30,31,32,33,34). The results emphasize that it is not practicable to determine the spatial variability of sulphate for the evaluation of the S nutritional supply, because to take soil samples for sulphate analysis, which show spatial relationships would require a prohibitive amount of sampling.…”

The mobility of soil sulphate is high on agricultural sites with soil pH values of higher than 5 due to a low adsorption capacity. Under humid conditions, the variability of soil texture and hydrological soil properties resulted in a high fluctuation of soil sulphate content within space and time. Investigations into the spatial variability of soil sulphate produce a coefficient of variation of the soil sulphate content between 15 and 100% at different soil depths, with the highest variation present in the deeper soil layers. The results of the geostatistical analysis indicate that a sampling distance of not more than 25 m is required to determine spatially correlated values. No correlation between the sulphate content of the soil and the total S status of cereals was determined from grid sampling on two sites in northern Germany, indicating that soil analysis of sulphate was not an appropriate method for the prognosis of the sulphur nutritional status.

“…Shan et al (1997) suggested that water-soluble and adsorbed sulfate are directly available to plants, and the mineralization of sulfate from organic S also makes an important contribution to plant-available S. Sulfate adsorption and plant availability increases as clay content increases, P fertilization decreases, and soil pH decreases (Camberato and Kamprath 1986). If clay accumulates in the root zone, responses to S are less likely because of increased plant-available S. Thus, wheat's response to S fertilizer occurs often on sandy soils because of low organic-matter contents and low S-adsorption properties, which increases sulfate loss through leaching (Martini and Mutters 1984;Oates and Kamprath 1985;Haron and Hansen 1988). According to Mahler and Maples (1987), applied S moved readily from the surface down to depths of 90 cm in a silt loam soil.…”

In recent years, sulfur (S) deficiencies in winter wheat (Triticum aestivum L.) have become more common, particularly on coarse-textured soils. In Study I, field experiments were conducted in 2001/2002 through 2003/2004 on Mississippi River alluvial soils (Experiment I) and an upland, loessial silt loam (Experiment II) to evaluate the influence of spring S rates of 0, 5.6, 11.2, and 22.4 kg ha 21 and a fall rate of 22.4 kg sulfate (SO 4 )-S ha 21 on grain yield of three varieties. In Study II, field experiments were conducted in 2001/2002 and 2004/2005 on alluvial soils to evaluate the influence of spring S rates of 0, 5.6, 11.2, and 22.4 kg SO 4 -S ha 21 in fields where S-deficiency symptoms were present. Grain yield response to applied S occurred only on alluvial, coarse-textured, very fine sandy loam soils (Study II) that had soil SO 4 -S levels less than the critical level of 8 mg kg 21 and organic-matter contents less than 1 g kg 21 in the 0-to 15-, 15-to 30-, and 30-to 45-cm depths. Soil pH increased with soil depth. Optimum S rate was 11.2 kg SO 4 -S ha 21 in 2001/2002 and 5.6 kg SO 4 -S ha 21 in 2004/2005. On the upland, loessial silt loam soil, soil SO 4 -S levels accumulated with depth, whereas organic-matter content and pH decreased. In the loessial soils, average soil SO 4 -S levels in the 15-to 30-and 30-to 45-cm soil depths were 370% greater than SO 4 -S in the surface horizon (0 to 15 cm).

“…Malavolta (1980) menciona que cátions acompanhantes como o Ca e Mg aumentam a absorção do sulfato, forma predominantemente absorvida pelas raízes. Martini & Mutters (1984) observaram que altas doses de CaCO 3 reduzem significativamente a disponibilidade de S, o que também foi observado no tratamento 1:0 (Tabela 4).…”

RESUMO -O objetivo deste trabalho foi avaliar o efeito da relação Ca:Mg do corretivo da acidez do solo na produção de matéria seca, composição mineral da alfafa, e nodulação. O solo utilizado foi um Latossolo Vermelho-Escuro distrófico. Utilizou-se o delineamento inteiramente casualizado em esquema fatorial com seis relações de Ca:Mg (1:0; 1:1; 2:1; 3:1; 4:1, na dosagem de 3,9 t ha -1 do corretivo e uma relação 3:1 na dosagem de 7,8 t ha -1 ) x seis épocas de corte, com quatro repetições. Mediram-se as produções de matéria seca (MS), teores de N, P, K, Ca, Mg e S na parte aérea, e peso fresco e massa seca dos nódulos, determinados no último corte. As mudanças na relação Ca:Mg não afetaram a produção de MS da alfafa. O dobro da dosagem de calcário recomendada apresentou a maior produção de MS. O teor de Ca e Mg foi diretamente proporcional à sua disponibilidade no solo, ao passo que o K foi inversamente proporcional ao teor de Ca. Não houve influência dos tratamentos nos teores de P. As relações Ca:Mg afetaram os teores de S na matéria seca, os quais foram menores nos tratamentos com maior quantidade de Ca. O tratamento 4:1 apresentou maior teor de N, e as maiores concentração de Ca no solo aumentaram a fixação de N à planta.Termos para indexação: cerrado, formação de nódulos, eficiência da nodulação, Latossolo VermelhoEscuro distrófico, matéria seca, Medicago sativa, nódulos, concentração de nutrientes. INFLUENCE OF CALCIUM:MAGNESIUM RATIO IN LIMESTONE ON NODULATION, DRY MATTER YIELD AND MINERAL COMPOSITION OF ALFALFAABSTRACT -This study evaluated the effect of different Ca:Mg ratios on dry matter yield, mineral composition of alfalfa, and nodulation. A dystrophic Dark-Red Latosol (Oxisol) soil was used in the experiment. A randomized design was adapted with five Ca:Mg ratios (1:0; 1:1; 2:1; 3:1 and 4:1) at a recommended limestone dosage of 3.9 t ha -1 . An additional treatment was included at a ratio of 3:1 with the dosage of 7.8 t ha -1 . All treatments had four replicates in six cutting times. The analyzed variables were dry matter production, concentrations (g kg -1 ) of N, P, K, Ca, Mg and S in dry matter and weights of fresh and dry nodules. The changes in the ratios of Ca:Mg at the recommended limestone rate did not affect the dry matter production. The highest dry matter yield was obtained in the treatment that used twice the recommended dosage. The concentrations of Ca and Mg in the aerial dry matter were directly proportional to their availability in the soil, while the K concentrations were inversely proportional to the rate Ca applied. No treatment influenced the concentration of P in the aerial dry matter. The concentration of S was influenced by the ratio of Ca:Mg and diminished with increases in Ca. The 4:1 treatment showed the highest concentration of N in the dry matter. The N fixation enhanced as the Ca rate in the soil increased.
