Resumo: | A greenhouse experiment was carried out at the Department of Agronomy - Universidade Estadual de Maringá. Surface soil material was sampled from a degraded area at Fazenda Experimetal de Iguatemi which presented unfavourable chemical characteristics such as low organic matter content, low pH, low phosphorus content and a toxic level of aluminium. In these soil samples the effect of phosphate fertilisers on the growth of two species of different plants: soy bean (Glycine max) cv. BR-37, and capim brizantão (Brachiaria brizantha) cv. Marandu were studied. Different sources of phosphorus fertilisers were used, being three from natural origin and classified as of high agronomic efficiency (Arad, North Caroline, and Gafsa), and a highly soluble (super simple phosphate). The fertiliser that promoted the largest dry matter production was the super simple phosphate, due to its high solubility and readiness to be absorbed, and/or for simultaneous sulphur supply in sulphate form. There was no difference in the dry matter production between the natural fertilisers. Soy bean developed better with the natural sources. This can be explained by its different capacity to dissolve the natural sources, since soy bean tends to lower rhyzosphere pH than Brachiaria brizantha. |

Foram utilizadas amostras de um solo oriundo da Fazenda Experimental de Iguatemi, Maringá-PR, degradado pela erosão e que apresentava características químicas desfavoráveis à prática agrícola, tais como: baixos teores de matéria orgânica, elevada acidez, presença de alumínio trocável em níveis tóxicos e baixos teores de fósforo. Estudou-se o efeito de adubos fosfatados sobre o crescimento de duas espécies de plantas distintas: soja (Glycine max) cv. BR-37 e capim brizantão (Brachiaria brizantha) cv. Marandu. Foram utilizadas diferentes fontes de fósforo, sendo três de origem natural, classificadas como de alta eficiência agronômica (Arad, Carolina do Norte e Gafsa), e um fosfato solúvel (superfosfato simples). O adubo fosfatado que promoveu as maiores produções foi o superfosfato simples, devido, provavelmente, à maior disponibilidade imediata de fósforo e/ou ao fornecimento simultâneo de enxofre na forma de sulfato. Não houve diferença na produção de matéria seca das plantas entre os adubos fosfatados naturais. A soja apresentou um melhor aproveitamento das fontes naturais, explicada pela solubilização dessas fontes, já que tende a apresentar um pH rizosférico mais baixo que o capim brizantão.Universidade Estadual de Maringá2008-07-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/428710.4025/actasciagron.v21i0.4287Acta Scientiarum.
