SOIL FERTILITY ISSUES OF AGRICULTURAL LANDS IN THE REPUBLIC OF CRIMEA

Abstract

Information on the soil cover structure in the Republic of Crimea and the soil's essential nutrient content is presented. An analysis of numerous literature sources and statistical data was conducted to highlight the main issues affecting the efficiency of agricultural production. The main problem lies in the need for more supply of cultivated crops with nutrients and organic matter. Weak accumulation of organic matter and nutrients leads to their deficiency and a shortfall in the quantity and quality of the obtained products. There needs to be more application of organic fertilisers to allow for the complete restoration of soil fertility. Although chernozem soils and their varieties dominate the soil structure of the Crimean Peninsula, there is a low content of available phosphorus and organic matter. The content of exchangeable potassium is characterised as elevated. Among micronutrients, the reserves of zinc, cobalt, copper, and manganese are characterised by low content, while the range of molybdenum and boron shows high levels. Agricultural producers can obtain environmentally friendly products since their concentration does not exceed the maximum permissible level.
