PHOSPHORUS is second in importance of the plant -••nutrient elements found to be deficient in Nebraska soils. Many crops grown on acid or alkaline Nebraska soils respond to applications of phosphate fertilizers. Nevertheless, blanket recommendations for the use of phosphate cannot be made in view of the fact that many of the soils supply sufficient phosphorus for plant growth, while with other soils, only certain crops respond in yield to applications of phosphate fertilizers. Investigations on the various aspects of the phosphorus problem have included determinations of the phosphorus status and related properties of • Nebraska soils. The procedures for fractionating the soil phosphorus, though somewhat empirical, merit being used until more direct methods are available to the soil chemist. The procedures used in the investigation of the nature of the phosphorus in the profiles of some eastern Nebraska soils have been used by other investigators in this laboratory. These fractionation techniques were based on the solubility of the soil phosphorus in different reagents (3, 13).
