Abstract
The article discusses key aspects of current trends in fertilizer application. A key feature is the inconsistency of the existing fertilizer system with scientifically sound standards. The consequences of the irrationality of nutrient input in the field of crop production are analyzed. It is determined that these trends have caused a number of problems, among which there is a chronic shortage of basic nutrients, soil erosion, growth of areas of land with high acidity, mineralization of humus reserves. Organic and mineral fertilizers and livestock rates have been systematized, which has made it possible to identify trends in farmland fertilization and to identify causal relationships between these indicators. It was found that the negative rate of increase in the livestock population directly affects the volume of fertilizer application and humus content in the upper fertile soil layer. It is estimated that the dominant situation in the field of production, supply and use of mineral fertilizers in Ukraine does not meet either the needs of the market or the conditions of agriculture in the country, which is due, first of all, to the shortage of potassium and phosphorus components, high cost and a significant share of imports. The consequences of this situation are the inferiority of providing the necessary nutrients for plants, the criticality of this dilemma is proved by the author's alculations of ecological damage, which was carried out on the example of prevailing agricultural plants in the croprotation: corn and winter wheat. The directions of solving the identified range of problems are consolidated in the form of the concept of economic and ecological balance of modern land use.
