Binding of phosphoric acid from the potassium primary phosphate takes place equally in chernozem and pseudogley soils. Exchangeably bound phosphorus quantity (PA) differs considerably and is much higher in chernozem. Increase of the potassium primary phosphate in both soils brings about the increase of actual acidity and reduction of the calcium concentration in the water stage of soil. The increase of actual acidity with increased fertilizer quantity and a simultaneous calcium concentration reduction process in the water stage of soil have considerable effects on the quantity of exchangeably adsorbed phosphorus in both investigated soils.
