Abstract

The method of phosphate fertilization is a factor that may affect soil phosphorus availability, directly affecting soybean (Glycine max) yield. Thus, the objective this study evaluated combinations of phosphate fertilization methods on lateral and depth distribution of phosphorus (P) in the soil, as well as soybean yield. Experimental design was randomized blocks, 5x4x8 factorial with split plots, evaluated within each fertilization method: 100% broadcast, 75% broadcast and 25% in the sowing furrow, 50% broadcast and 50% in the row, 25% broadcast and 75% in the sowing furrow, 100% in the sowing furrow and control (No P fertilization), with four replications. The P content was evaluated at the depths 0-5, 5-10, 10-15 and 15-20 cm and in eight lateral distributions every 5 cm (starting between two rows, through the sowing furrow and finishing in the middle of the next row). The method of broadcasting 100% of phosphate fertilization did not present differences in the evaluations of lateral distribution for phosphorus content, however, the methods of phosphate fertilization 75 and 100% in the sowing furrow performed better at the depths 0-5 and 5-10 cm, exactly on central lateral distributions. Increased plant height and soybean yield were observed as the amount of phosphorus increased in sowing furrow instead of broadcast application.
