AnnotationDue to extensive development of agriculture and forestry, inefficient introduction of protected and other environmental affairs, the ratio of arable land, natural fodder lands, forest and water resources has been disturbed that has resulted in the intensive development of erosion processes, compaction of arable soil, soil compaction, stability of natural landscape of Ukraine. The current situation is caused by the fact that, for many decades, extensive use of land and, especially arable land, has not been secured by the appropriate measures for soil reproduction. This is the main reason for low efficiency of the measures, used to intensify agriculture, and the complex of degradation processes depletes soil production resources, reduces crop yields. On a large share of the agricultural land area, the limits of ecological balance of soil ecosystems and agrocenoses have been reached. Water and wind erosion, irreversible loss of humus and nutrients, salinization and acidification of soil, drying and wetting, including water logging, pollution by industrial waste and emissions, poisoning cause the greatest damage to soil. According to the results of agrochemical research, the customer receives comprehensive and true information about chemical composition of the soil and its physic-chemical parameters. That information provides an idea of the availability of soil nutrients, needed for plants. Specialists carry out qualitative sampling of soil for coordinating points and binding to a specific area, agrochemical analysis, development of cartograms and calculation of fertilizer rates for the proposed crop. Agrochemical study of soil involves the examination of their agrochemical and other characteristics, establishing the value of land. Due to the agrochemical study of soil, the content of humus, macro and micro-elements, soil reaction and so on are obtained. As a result, the certification has been carried out.
