- The rate of release of macronutrients from new granulated organic-mineral fertilizers formed from spent mushroom substrate was investigated in the conditions of a microplot experiment in the laboratory. Nitrate(V) and ammonium were estimated using a colorimetric method using a flow auto-analyzer after extraction in 1% solution K2SO4 and in 0.01 mol · dm - 3 CaCl2, pH-value – by potentiometric method after extraction with 1 mol·dm - 3 KCl, available P and K by the Egner-Riehm method. New granulated organic-mineral fertilizers formed from spent mushroom substrate had an impact on the pH-value seven days after application. This tendency was intensified in the following weeks. New granulated organic-mineral fertilizers were a source of available form of nitrogen (nitrate(V), ammonium), potassium and phosphorus.
