Kaerblane, H. | Kevvai, L. | Kanger, J.
The content of lactate soluble P2O5 decreased up to 0.10...0.47, and potassium up to 0.5...0.8 mg kg sup (-1) in the nonfertilized soil during a year. In the case of annual application of kg P2O5 per hectare during 13 years the content of P2O5 increased 4.5 in peble loamy Rendzina and 1.2 mg kg sup (-1) in sandy loam Podzol per year. The content of lactate soluble potassium started to increase significantly in the soil if the application rate of K2O overfulfils 75 kg per year
