Conteúdo: 	The objective of this work was to evaluate agronomic and P recovery efficiencies of a granulated organomineral phosphate fertilizer (OMF) produced from poultry litter, compared with those of monoammonium phosphate (MAP), in soils with different textures. The experiment followed a 2x2x4+2 factorial arrangement, with two Oxisols (sandy loam and clay loam textures), two sources of P (OMF and MAP), four levels of P (50, 100, 200, and 400 mg kg-1), besides two control treatments without P application. The treatments were evaluated in 10-kg pots filled with soil, during four successive cultivations of corn without replacing the P absorbed by the plants, in order to evaluate the actual and residual effects of the fertilizers. Available P contents in the soil were higher with the MAP fertilizer in the sandy loam soil, with no significant differences between fertilizers in the clay loam soil. OMF had a greater immediate effect and promoted a higher dry matter yield in the first cultivation; however, the residual effects of the fertilizers did not differ in the other cultivations. P accumulation by plants was not affected by the fertilizer used. OMF had higher agronomic efficiency, but P recovery efficiency did not differ significantly between fertilizers. OMF performance indicates good potential use of poultry litter as fertilizer, in organomineral formulations.
