Calcium limestone and dolomitic limestone were applied to Tama silt loam in pots in the greenhouse. The soil had a lime requirement of 3 tons per acre ancl the pH was 5.30. Rock phosphate was applied at the rate of 250 pounds per acre alone and in combination with calcium limestone and with dolomitic limestone. Samples of the variously treated soils were taken after 4, 8, 12, and 18 weeks for the determination of pH and available phosphate.
