The addition of organic residues to the soil may modify the amounts of plant available phosphorus (P) found in this system. These studies were undertaken to evaluate the suitability of the sorption isotherm technique for estimating the amounts of inorganic P requaired for optimum plant growth, the correlation of P availability with the amount of P extracted by three chemical methods, and with the activity of two phosphate enzyme, when soil were amended with organic materials. Barley straw (Hordeum vulgare L.), green manure (Cowpea, Vigna unguiculata (L.) Walp), dairy manure and sewage sludge were added to four soils at the rates of 9, 18, 27 and 36 Mg ha-1, for both laboratory and greenhouse experiments, and incubated for 90 days. Sorption isotherm curves ....were obtained for each treatment; from these the amounts of inorganic P fertilizer required to produce a concentration of 0.2 ug ml-1 in the equilibrium solution were calculated. These P requirements were tested in a greenhouse experiment using corn (Zea mays L.) as the indicator plant. Additions of all organic materials studied decreased soil P sorption capacity, and the changes were proportional to the P concentration and the dosage of the organic materials. The sorption technique successfully predicted the amounts of P required for maximum yields in both soils, but seemed to be more generally applicable in the soils with the largest P sorption capacity. Phosphate availability indices according to three extraction procedures (water, double acid and resin)...
