Agroecological typing of lands in the reclaimed territory in the Non-chernozem zone

Abstract

Involvement in agricultural circulation of unused and unproductive lands and the formation of a rational structure of land is possible only if the conditions necessary for the growth and development of crops are created. he latter is impossible without land reclamation, which is carried out in order to increase the productivity and sustainability of agriculture, ensure guaranteed agricultural production based on the conservation and increase of land fertility. The purpose of the research is to carry out agroecological typification of the lands of the reclaimed area. The object of research is the territory of the Kondratovsky rural settlement, located in the Perm municipal District of the Perm Kray. Agricultural land use is of great importance in providing the region’s population with vegetable products. The total research area was 5815.6 ha, including 2682.79 ha of reclaimed land. The site includes 43 fields, the area of which was 2173.1 ha. For soil mapping, a large-scale soil map on a scale of 1:10,000 of the Verkhnemulinsky state farm was used. Based on the raster soil map, 1010 soil cartographic units were identified. Marsh lowland, alluvial marsh, soddy-gley, soddy podzolized soils, as well as their reclaimed analogues, were distinguished. According to the granulometric composition, heavy soils (clay and heavy loamy) predominate. An agroecological typification of the lands of the reclaimed territory of the Kondratovsky rural settlement was carried out. Agroecological typification is based on spatial data characterizing the relief of the floodplain, the soil cover and the current boundaries of the agricultural use of the territory. The agroecological grouping of soils was performed using the Aggregation GIS-analysis function. On the reclaimed territory, one agroecological group has been identified—floodplain. Two agroecological land types have been identified: 1) elementary soil areas and patchiness of alluvial-meadow and alluvial-soddy soils; 2) complexes of alluvial meadow and alluvial-marsh and marsh lowland soils. The limiting factors and features of the use of these types of land have been established. To bring the research results to the administrations of a rural settlement, the Perm regions and land users, a Web-GIS application has been developed, access to which is organized through the GitHub platform.
