MONITORING OF AGRICULTURAL LANDS CONDITION IN VLADIMIR REGION

Abstract

The concept of state land monitoring development, adopted by Government decree No. 1292-r dated 07/30/2010, provides for the formation of information resources about lands, including a qualitative as-sessment of land fertility. In connection with it, a need arose to update land fertility data carried out by soil surveys institutes Rosgiprozem and Roszeproekt in the 60-80s. On the maps of administrative division of Vladimir region and natural-agricultural zoning, an administrative-agricultural zoning of soils of Vladimir region was carried out. Based on the synthesis of data from the Unified State Register of Soil Resources of Russia, administrative-agricultural zoning, the spatial distribution of t totality of soil differences is deter-mined and a system of soil-territorial allotments is formed. Based on the system of soil-territorial divisions of Vladimir region, geographical coordinates of soil samples selection were established, for which in 2018 monitoring of agricultural lands in Vladimir region was carried out. Our analysis of the dynamics of soil fertility showed that over the past years (from 1961 to 1995) there have been significant changes. The course on the chemicalization of agriculture in the 70-80s of the last century led to a significant increase in humus in the soil, macrocells and a decrease in acidity. Liberal agricultural reform in the 90s of the last century led to a significant decrease in sown areas. A significant part of the area of arable land passed into a deposit or overgrown with forest. It led to the conservation of previously intensively used sown areas, to the conservation and increase of organic matter and nutrients in the soil.
