Efeito do fosfato natural, hiperfosfago e superfos­fato triplo em latossolo vermelho escuro distrófico- unidade Goiânia, na produção de glycine max (l) merril (soja). Anais da Escola de Agronomia e Veterinária, Goiânia, v. 19, n. 1, p. 59-64, jan./dez. 1989.

The sources of P compared were: natural pbosphate lhinner crushed (FN), hiper­fosfago (H), hiperfosfago (HM) having fertilization of maintenance sarne own hiperfos­fago, and lhe tripie superphosphate (ST), used in band seeded as fertilizatlon in three dif­ferent treatmonts, had not been used in one of the treatments with hiperfosfago (HM). The soil was a LED Agronomy, Unit, oxisol, that showed for the deptb of "O" to 17 cm and 17 to 34 cm, the following values: pH = 5.1 and 4.8; Ca + + = 2.4 and 2.0 meJlOO mi; P = 0.6 and 0.3 ppm; K = 49 and 39 ppm and "O" meJlOO mi of AI+ +3 permutable. The doses used were: "O", 200, 400 and 600 kg of P205 by hectare. Soybean planted showed response for the different doses of phospborus, althougb for lhe natural phosphate had not been significant.porAcesso AbertoArtigo
