Abstract: The phosphorus adsorption capacity of soil in the presence and absence of HA and FYM was determined by adding 0, 10, 20, 40, 60, 120, 240 and 360mg L-1 (initially applied P, IPA) to 5g soils with and without HA (10mg kg-1) and FYM (20g kg-1) .The soils along with respective phosphorus solution were taken in duplicates, were shaken on horizontal shaker for 30hr continuously. The suspension were then filtered through whattman-42 and analyzed for P which represented the equilibrium P concentration (EPC). These soils were then applied another 45 mL distilled water and shaken for 24hr for desorption study.
