Factors Affecting Transformation Of Some Nutrients In Soils

There are so many resticions to minimizing of soil P and hence its availing in soils all over the world. Therefor P fertilizer supplementals repesent a cornerston in land agricultural ultilization. Soils buffering capacity and changes in their PH, relative abundance of main inorganic P fractions in soils were considerd as parameters for monitoring the status available P in the two investigated soils which were treated with different P sources and incubated for about 6 months. Also, the relative abundance of decomposed soil organic components i.e humic and Fulvic acids were determine through the course of experiment.
