Changes of potassium and phosphorus content of podzoluvisol in long-term experiment on fertilizer application

Abstract

The long-term organic and mineral fertilizer application has increased the contents of all forms of phosphorus and potassium in plough layer of Podzoluvisol. Liming also has affected positively on phosphate and potassium status of soil. The different forms of phosphorus and potassium are among themselves in dynamical equilibrium among themselves.
