Effects of biochar on available P fractions, soil properties and P uptake by pl...
Auxtero, E.; Madeira, M.; Monteiro, M.C.H.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 strategi...
Extractability of P in major soils of Angola as affected by P fertilizers and l...
Auxtero, E.; Madeira, M.; Monteiro, M.C.H.Phosphorus (P) deficiency is the major constraint to crop production in most tropical soils (Sahrawat et al., 2001). In Angola, such constraint (i.e, low concentration and low P solubility) has also been reported to limit crop production in many agricultural soils (Ucuassapi, 2006). These soils may require application of inorganic P through soluble and relatively reactive phosphate rock sources, and lime (Dober...
