Abstract
O efeito de doses crescentes de calcário magnesiano, fósforo e potássio sôbre a produção de soja foi estudado por dois anos em solo Podzólico Vermelho Amarelo, variação Piracicaba, com pH 5,5, adubado com fósforo nas três culturas anteriores à experiência. Não houve resposta à adubação potássica. A reação ao calcário só se manifestou no segundo ano, quando a dose menor, de 1 t/ha, aumentou a produção em 9%. O efeito do fósforo foi significativo e linear; contudo, em média dos dois anos, o aumento proporcionado pela dose maior, de 100 kg/ha de P2O5, correspondeu a apenas 9%.
The effects of increasing doses of magnesian lime, phosphorus and potassium on the yield of soybeans were studied during two years on a red-yellow podzolic soil with pH 5,5, fertilized with phosphorus in the previous three crops. No response to potassium was obtained. The effect of lime manifested only in the second year, when the smaller dose, of 1 metric ton per hectare, caused an yield increase of 9 per cent. The responses to phosphorus were linear; however, the increase due to the larger dose, of 100 kg/ha of P2O5, corresponded to 9 per cent only.
