Journal Article 1999

Autor: Haque, I. Lupwayi, N.Z. Ssali, H.

The majority of soils in Africa are P-deficient, but the high cost of conventional, water-soluble P fertilisers limits their use by resource-poor farmers. Rockphosphates are a low-cost alternative. The relative agronomic effectiveness of unacidulated (RP), 25 percent partially acidulated (PARP25)...

Although the majority of soils in Africa are P deficient, the high cost of conventional water-soluble P fertilizers limits their use by resource-poor farmers. Rockphosphates are a low-cost alternative. The effect of Egyptian rockphosphate (ERP) from two sources, applied at 50 kg P ha-1, on annual...
