Abstract. In recent years, a lot of information has appeared that indicates the deterioration of a state of chernozem soils. The investigations were carried out in order to analyze the changes in the agrochemical state of soils of the forest-steppe of the Central Black Soil Region on the example of Chernyansky District of Belgorod region. The long-term annual average value of the hydrothermal coefficient according to Selyaninov in the region is 1.1. The soil cover was represented by leached typical chernozems and gray forest soils. The share of eroded arable land is 53.2%. In the work it was used materials of a complete agrochemical survey. The aim of the work was to analyze the changes in agrochemical parameters of soils during 2008–2017. In 2013–2017 it was determined that the application of 4.2 t/ha of organic fertilizers and 89.2 kg/ha of mineral ones provided a high yield of winter wheat (4.55 t/ha), barley (3.29 t/ha), corn grain (5.94 t/ha), root crops of sugar beet (46.2 t/ha). In 2008–2017 it was limed 24,200 hectares of acidic soils, as a result, the share of acidic soils reduced from 63.8 to 35.7%. There is a significant increase in the content of mobile forms of potassium in arable soils. At the same time, the availability of zinc, copper, manganese, cobalt, and sulfur remains low, and some decrease in the content of organic matter and phosphorus is observed.
Keywords: liming; soil acidity; trace elements; organic matter of soil; soil fertility; mobile forms of phosphorus and potassium; chernozem; fertilizers.
