Resumo: Eleven phosphate sources were tested in a Dark Red Latosol (Haplustox). The performance of these materials was evaluated during four years, with the following crop sequence: wheat, soybean, soybean, rice. According to the results, the phosphate sources can be ordered in four groups of decreasing performances: a. Supertriple, Gafsa phosphate and Magnesian Thermalphosphate: b. IPT Thermalphosphate, Pirocaua, Florida and Tennessee phosphates; c. Patos de Minas, Araxá and Abaetá phosphate; d. Catalão phosphate. The results also indicated that the effectiveness of rock phosphates improved when the soil acidity was higher; however, crop performance depended on a balance of factors such as soil acidity, availability of phosphorus, and plant adaptation.

Durante quatro anos, foi feita a avaliação da eficiência agronômica desses fosfatos, utilizando-se a seguinte sequência de cultivos anuais: trigo, soja, arroz. Os resultados até o momento permitem classificar as fontes testadas em quatro categorias, de acordo com sua eficiência agronômica, em ordem decrescente: a. Superfosfato triplo, fosfato de Gafsa e termofosfato magnesiano; b. Termofosfato IPT, fosfato de Pirocaua, fosfato de Flórida/USA e fosfato de Tennesse/USA; c. Fosfato natural de Patos de Minas, de Araxá e de Abaeté; d. Fosfato natural de Catalão. Foi ainda mostrado que a eficiência dos fosfatos naturais melhora com o aumento da acidez do solo; contudo, o melhor desenvolvimento vegetal exige um equilíbrio entre os fatores: acidez do solo, disponibilidade de fósforo e adaptação de plantas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraGoedert, Wenceslau J.Lobato, Edson2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16573Pesquisa Agropecuaria Brasileira; v.15, n.3, mar. 1980; 311-318Pesquisa Agropecuária Brasileira; v.15, n.3, mar. 1980; 311-3181678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16573/10853info:eu-repo/semantics/openAccess2014-04-15T19:32:36Zoai:ojs.seer.sct.embrapa.br:article/16573Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:32:36Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
