Abstract: The aim of the research was to evaluate the organic fertilizer application impact on soil humus horizon productivity parameters in different agrocenosis. Soil properties have been evaluated in perennial pastures, winter wheat (Triticum aestivum L.) and field pea (Pisum sativum L.), where only arable is annually fertilized with manure and slurry, respectively, 35-40 t ha-1 and 7 t ha-1. It was estimated, that manure and slurry fertilization, mainly, reduced the soil acidity and, in particular, increased the humus content in arable soil humus horizon. Increase in mineral nitrogen content was significant only in ploughing horizon of winter wheat crops. As it was obvious, that organic fertilizers have been intensively mineralized in the winter wheat humus horizon. However, in perennial pasture as well as in field pea humus soil the immobilization and mineralization of organic matter was in close equilibrium
