Mineral fertilizers for dry beans: XI - Effects of N, P, K and liming on poor "campo" soils of the southern section of the Paulista Plateau

Two experiments with dry beans (Phaseolus vulgarisL.) were conducted for two years in the southern section of the São Paulo Plateau to study the responses to the indicated treatments. The application of dolomitic lime and principally that of phosphorus were the factors that controlled the yields. Both materials were more effective when applied in the presence of one another. The immediate and residual effects of phosphorus were similar, but liming acted better in the second year.
