Improving the technical approach to managing the process of local treatment of drainage runoff from irrigated lands

Purpose: to characterize the main sources of irrigation water in steppe zone Crimea and assess prospects for their further use. Materials methods. Statistical information on resources use irrigated agriculture results monitoring observations over resource composition part peninsula are considered. To feasibility using limitedly suitable waters agriculture, phytotesting radish corn seeds con-ducted. Results. The system North Crimean Canal (more than 30 million cubic meters were used 2022) wells. However, wells some cases belong category limited use, as agricultural sector can lead a deterioration reclama-tion situation decrease crop yields. An analysis statistical data production territory one farms Pervomaysky district, where groundwater has been more 5 years, did not show significant change level productivity comparison with average lands republic. confirmed that an increase mineralization 3 g/l form inhibitory effect germination. Conclusions. When justifying choice source Crimea, besides yields, preliminary assessment suitability irrigation, it is necessary take into account climatic soil conditions, drainability territory, content source, proposed methods list crops. In case waters, conduct mandatory condition order identify prevent timely reclamation situation.
