Phosphorus Requirement of Oat Fodder by using Adsorption Isotherm

📗 Most of the Pakistan soils (> 90 %) are deficient in available P and the native P supply cannot cope with P mining due to continuous cropping where as the over fertilization of P posses direct threat to environment. Soils have different P adsorption capacities, which are rarely taken into account while applying P fertilizers.
