Suitability of Agrochernozem Soils for Irrigation Amelioration in the Southern Forest–Steppe Zone of the Republic of Bashkortostan

In the current climate aridization trend, irrigation amelioration is becoming increasingly important for the sustainable growth of heavy crops. The intensification of agricultural practices creates degradation risks for the soil cover. In this context, studies of soils intended for irrigated agriculture to prevent their degradation are of utmost importance. A soil-ameliorative survey of agrochernozem soils was conducted in the Pre-Urals southern forest–steppe zone, Sterlitamak district, Republic of Bashkortostan. The collected data indicate that the soil cover in the study area is constituted by Haplic and Luvic chernozem soils. These two soils are similar in their hydrophysical, physicochemical, agrochemical, and environmental properties, are highly resistant to degradation processes, and are suitable for irrigation amelioration.
