Abstract:

The results of many years of research, the object of which was long unused irrigated lands of the steppe and dry steppe zones of the Volga region, are presented in the article. In the course of the work, the agroecological and reclamation state of the irrigated lands of the steppe and dry-steppe zones of the Saratov Volga region was assessed. An analysis of the reclamation complex is given. 30 districts of the Saratov region have irrigated lands. The base of the irrigated land is reclamation systems and they are located in the most arid part of the region – the Volga region. 99.8% of irri-gated lands is concentrated in 299 farms of Saratov region, including 42.5% in the areas of chernozem steppe, and 48% in the dry steppe. About 75.7% of the irrigated land is in good condition. But along with this, in all areas of the Saratov region there are irrigated lands that are in unsatisfactory condition by reason of groundwater level, salinization, salinity, groundwater level and salinization, groundwater level and salinity. Conclusion is given that in spite of large irrigated areas in the Saratov region, part of them has been withdrawn from agricultural circulation and this part needs to be restored, especially in the Left Bank of the Volga River, where it is impossible to obtain guaranteed crop yields without irrigation. It is necessary to have at least 350,000 ha of irrigated land for stable functioning of the agro-industrial complex of the Saratov region. The suggestions of efficient use of irrigated land is given in the article.
