Resumo: Low phosphate (P) availability is one of the major problems in most Ferralsols from Angola, due to the strong ability of these soils to adsorb P, thereby limiting its bioavailability for crop production (Ucuassapi, 2006). Application of biochar as soil amendment, along with superphosphate and rock phosphate fertilizers may be useful in increasing supply of available P. However, appropriate P management strategies may require information on the fate of biochar and applied P fertilizers in the soil as well as on their interaction with soil colloidal constituents. Therefore, information on soil P availability using different methods, and P forms (inorganic and organic) by Hedley modified fractionation procedure (Tiessen and Moir, 1993), early plant growth performance and P content in plant after biochar amendment along with different rates of P fertilizers, is crucial for making appropriate fertilizer and biochar recommendations for crops.
