What is the effect of soil pH on the available forms of Phosphrous(P) in the soil solutionand the dominant Phosphrous(P) species in the soil. Comparing the relationship between labile soil Phosphrous(P) and solution Phosphrous(P)in a clay and in a sand and explain how this relationship determines the rate of Phosphrous(P)fertilization.
