The importance of proton supply in phosphate rock dissolution: Comparative study of three phosphate rocks from sub-Saharan Africa

The dissolution in hydrochloric acid of three phosphate rocks (PRs) from sub-Saharan Africa was studied in the laboratory and their agronomic effectiveness compared using soils from Tanzania, Ivory Coast, Kenya and Netherlands. The objective was to investigate the potential of the PRs in supplying phosphorus under conditions of limited and unlimited supply of protons (H+). The test crop was maize (Zea mais var. LG11)....
