When assessing the ecological state of drained agricultural landscapes exposed to pollution, the average daily dust load, the chemical composition of the snow cover of the drained lands, the elemental composition of soils and the yield of perennial fodder grasses were determined. Snowfall, which is a good indicator of airborne technogenic fallouts, was classified as contaminated near the mining site, as opposed to the case of road traffic. Although the average daily dust load was very high the total level of chemical pollution near the quarry was low. Depending on the type of technogenic impact, the sequences of macro- and microelements accumulation in the snow cover were identified: quarry - Al > Mn > Mg > Ca > Fe, highway -Cr > Al > Mg > Pb > Ca > Co. Depending on the physical properties of the soils and technical features of the drainage network, Multidirectional trends in the inflow of pollutants into the upper horizons of the farmland soils with surface waters were noted. According to the results of this study, the yield of perennial fodder grasses increases with distance from the pollution sources under both types of technogenic influence.
