Summary, etc. Two phosphate rocks, one from Pesca (Colombia) and the other from Togo, were acidulated to various degrees with H('2)SO('4) and H('3)PO('4) for evaluation in varyinggranule size ranges. Products acidulated with H('2)SO('4) were also prepared using different drying temperatures. Phosphorus availability was measured by dry-matter yield and P uptake in greenhouse experiments with maize. It was observed that partial acidulation with H('2)SO('4) was effective in increasing the water-soluble P level of phosphate rock when the drying temperature of the productwas not excessive. Crop response and P uptake were both highly correlated to the water
