| dc.description | Phosphorus deficiency is common in Oxisols of the Brazilian Amazon. For c1ayey Oxisols, P fertilization could become an important economic factor, as their P sorption capacities are high, in the same range as those in Oxisols of the Cerrado region. Although several studies have demonstrated marked yield responses to P fertilization with annual crops on these soils, information has been needed on soil-test calibrations and the long-term effects of different strategies for P fertilization. The objectives of this project were: 1) to obtain detailed P response curves and soil-test calibration data for the main annual crops cultivated in the region; 2) to obtain a description of the residual P fertilizer value, and 3) to provide indications of appropriate maintenance P fertilizer rates for sustaining adequate crop yields. | eng |
