After three years of the studies, organic carbon content in soil decreased as compared to the initial value. However, after five years the content increased by 8.6 percent under Dactylis glomerata. Total nitrogen content in soil at initial period of the investigations increased, whereas after five years decreased and similar level under both grass (Dactylis glomerata and Bromus unioloides) cultivations was noted. Fertilization with nitrogen differentiated carbon and nitrogen content in soil to the greater extent than fertilization with potassium
