The objective of this study was to determine content of basic mineral components and pH of the soil fertilized with varying types of organic fertilizers and different rates of nitrogen fertilizer. Nitrogen fertilization insignificantly decreased pH of soil in general. Content of organic carbon, nitrogen and total phosphorus in soil during growing season of sugar beet was higher at plots with ploughed down stubble crop than after applying manure. Using of manure increased content of potassium especially in ploughing layer. Intensification of nitrogen fertilization slightly increased content of total nitrogen in ploughing and subsoil layer
