THERMODYNAMIC EVALUATION OF THE POTASSIUM AND PHOSPHORUS STATUS OF CHERNOZEMS IN AREAS OF SOIL-PROTECTIVE AGRICULTURE

Thermodynamic investigations of the potassium phosphate status of the soil solid phase and solution of an Ordinary Chernozem in an area where soil-protective cultivation has long been practiced indicated that this type of tillage increases the mobility of phosphorus and potassium and enhances the ability of soils to give up nutrients to the soil solution.
