The purpose of this research was to evaluate the effects of P and Si fertilizer rates in dynamic of P fractions in clay soil under greenhouse. The research was carried out in a Dystroferric Red Latosol of a very loamy texture from Lavras city, Minas Gerais State, Brazil. The experimental design was entirely randomized, arranged in 4 × 3 factorial design, with four repetitions. The treatments included four inorganic fertilizer P rates (0, 110, 330 and 560 mg dm-3) and three Si rates (0, 110, 330 and 560 mg dm-3). The preview application of Si fertilizer did not contribute to decrease P desorption. Possibly, the silicate has lower affinity with the bound sites of adsorption than phosphates. The effects of inorganic fertilizer P were higher in increasing the moderately labile and labile P inorganic fractions. Among the organic P fractions, the NaHCO3-Po fraction was the only one that contributes to plant nutrition. The Hedley sequential phosphorus fractionation promoted information about different pools where P was accumulated in the soil after common bean cultivation. The highest amount of P was obtained in stable P fraction, followed by moderately labile and labile P fraction. The moderately labile P fraction decreased after common bean cultivation possibly due to the time of P contact in the soil and redistribution to stable P fraction. The labile form was the lowest P pool in soil; nevertheless the increase in fertilizer P rates increases the amount of P content in labile fraction.

A regiao dos Cerrados Continuos e uma das mais importantes regioes cafeeiras do Brasil e esta dividida em doze sub-regioes. A producao de cafe desta regiao representou 3,3% e 21,2% da producao nacional em 1975 (2 544 596 t) e 1993 (2 557 518 t), respectivamente. Tambem apresentou um grande aumento na area colhida e a maior produtividade. Embora concentrada nos Cerrados mineiros, observou-se a ocorrencia da cafeicultura em 543 municipios em todos os Cerrados continuos; entretanto, somente 27 eram responsaveis por 54,2% da producao de cafe dos Cerrados. Por outro lado, o setor cafeeiro do Brasil nao acompanhou a evolucao mundial deste produto. Isso representa serios riscos para a cafeicultura nacional. Assim, ha necessidade de politicas mais agressivas com enfase em pesquisa. |
