Resumo: Research data have demonstrated that the P demand of coffee (Coffea arabica L.) is similar to that of short-cycle crops. In this context, the objective of this study was to evaluate the influence of annual P fertilization on the soil P status by the quantification of labile, moderately labile, low-labile, and total P fractions, associating them to coffee yield. The experiment was installed in a typical dystrophic Red Latosol (Oxisol) cultivated with irrigated coffee annually fertilized with triple superphosphate at rates of 0, 50, 100, 200, and 400 kg ha-1 P2O5. Phosphorus fractions were determined in two soil layers: 0-10 and 10-20 cm. The P leaf contents and coffee yield in 2008 were also evaluated. The irrigated coffee responded to phosphate fertilization in the production phase with gains of up to 138 % in coffee yield by the application of 400 kg ha-1 P2O5. Coffee leaf P contents increased with P applications and stabilized around 1.98 g kg-1, at rates of 270 kg ha-1 P2O5 and higher. Soil P application caused, in general, an increase in bioavailable P fractions, which constitute the main soil P reservoir.

Nesse contexto, o objetivo deste trabalho foi avaliar o status do P no solo, em função da aplicação anual de doses de P, por meio da quantificação de frações de P lábeis, moderadamente lábeis, pouco lábeis e P total, associando-as às produtividades do cafeeiro. O experimento foi instalado num Latossolo Vermelho distrófico típico (LVd) cultivado com cafeeiros irrigados em produção, submetidos a adubações fosfatadas anuais de 0, 50, 100, 200 e 400 kg ha-1 de P2O5, como superfosfato triplo. Foram determinadas frações de fósforo no solo nas profundidades de 0-10 e 10-20 cm. Também foram avaliados teores foliares de fósforo e a produção dos cafeeiros em 2008. O cafeeiro irrigado respondeu à adubação fosfatada em fase de produção, com incrementos de até 138 % na produtividade com a aplicação de 400 kg ha-1 de P2O5, na safra avaliada. Os teores foliares de P no cafeeiro aumentaram com o aumento das doses de P e se estabilizaram em torno de 1,98 g kg-1 a partir da dose de 270 kg ha-1 de P2O5. A aplicação de fósforo ao solo promoveu, em geral, incrementos nas frações de P biodisponíveis, sendo estas o principal reservatório de P do solo.Sociedade Brasileira de Ciência do Solo2017-03-31T11:07:13Z2017-03-31T11:07:13Z2011-03info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfREIS, T.
