  1. ASSESSMENT OF SOIL RESISTANCE TO EROSION OF IRRIGATION RECLAMATION AzamatSuleymanov Azamat Suleymanov1, Ilyusya Gabbasova2, Ruslan Suleymanov2, Irik Saifullin2 1Moscow State University of Geodesy and Cartography, Moscow, Russia  2Ufa Institute of Biology of the Russian Academy of Sciences, Ufa, Russia 

  2. The studies were conducted on the territory of the Republic of Bashkortostan (Russia)

  3. The research was carried out in the southern forest-steppe zone. The territory on which research is characterized by a typical continental climate with sharp temperature contrasts: cold, harsh, with little snow winters and hot summers, a rapid transition winter to summer, the number of unstable and scarce precipitation during the growing season.  The investigated site is located on a plateau and slopes leveled mainly western and southern exposure with an altitude of 202 to 150 m. In mesorelief allocated little hilly and karst downgrade. Soil-forming rocks are eluviumlimestones and deluvial calcareous clay. The main background of the soil cover is represented by grey forest residually calcareous soils. On steep slopes formed sod-calcareous soil typical. 

  4. Soil map of the area using under irrigation

  5. Agrochemical properties of soils

  6. Water-physical properties of soils

  7. Water permeability of grey forest soils The water permeability of the soils is characterized as a «good» (70-100 mm/1 hour)

  8. The concentration of heavy metals in soils, mg/kg

  9. GIS Project

  10. Conclusions • Thus, our study on the stability of the soil under irrigation has shown that two types of soils formed in the studied area: Grey forest residual-calcareous (GreyicPhaeozemsAlbic) and Sod-calcareouses (RendzicLeptosolsEutric) soils.  • The Grey forest residually-calcareous moderately low humus heavy-loamy slightly eroded formed on eluvium limestone and calcareous clay talus characterized by satisfactory agrochemical and water-physical properties, but the insufficient resistance to anthropogenic impacts, erosion-dangerous, suitable for irrigation only when growing vegetable crops. When used these soils in the vegetable crop rotation is recommended to apply 40 t/ha of manure as well as nitrogen, phosphate and potash fertilizers to meet the requirements of specific vegetable crops. To prevent water and wind erosion is necessary to carry out anti-erosion measures, including snow retention, soil tillage and sowing crops across the slope and others.  • The Sod-calcareouses (RendzicLeptosolsEutric) low-power a low humus content heavy loam medium eroded formed on steep slopes prone to erosion and are characterized by low resistance to irrigation. These soils are not to be irrigation.
