Abstract
The results obtained showed that for all CaCO3 levels, the phosphate sorption was increased with the increase in the added phosphorus
from 5.0 to 1000 µg g-1 soil. It was further observed that at 10% calcium carbonate no precipitation of calcium phosphate was noticed
even at higher phosphorus additions. However, when the calcium carbonate level was increased from 20% to 50%, the calcium
phosphate precipitation was apparent at the phosphorus additions of 500 and 1000 µg g-1 soil respectively.
