The results of the analysis of the annual variability of total depositions of nitrogen and phosphorus compounds in the Middle and Lower Volga basin over the period of 2011—2015 are presented. The atmospheric deposition of nitrogen and phosphorus compounds are calculated. The main features of the spatial distribution of the nutrient load of wet atmospheric deposition of nitrogen and phosphorus compounds in the Middle and Lower Volga basin are identified. It was established that the moduli of the deposition of nitrogen and phosphorus compounds amounted to 0.7 t N km^–2 year^–1 and 0.027 t P km^–2 year^–1.
