N2  - Development of a laboratory method for predicting the phosphate requirements of pasture plants, in pounds phosphorus per acre, is described. Measurement of the phosphate sorption by soil at a standard equilibrium concentration was used. Predictions made by using this method in the following year on different soils accounted for over 85&#37; of the variability in phosphate requirement. A good correlation between phosphate sorbed and phosphate required was found. The relationship was linear over the range 0&ndash;500 p.p.m. of sorbed P. While different sampling depths, equilibrium concentrations, and degree of soil mixing affected the relationship, it remained linear and the correlation coefficients close to 0.9.
