Purpose. Features spatial-temporal distribution of major ions, organic matter and nutrients downstream. Methods. The chemical-analytical. Results. The results of spatial and temporal distribution of chemical elements by the length Southern Bug river. It was shown that changes of major ions concentrations due to the location of the natural features of the river. The long-term dynamics of nutrients in the water of the river Southern Bug and the estimated impact of Khmelnitsky city on it condition were studied. Conclusions. The surface water of the river within the influence of Khmelnitsky city characterized by chronic pollution of ammonium nitrogen and phosphorus mineral.

It is shown that two-times application of silicon- potassium concentrate on leaves can optimise not only potassium but also nitrogen and phosphate components of plants. The effectiveness of the detox-effect of silicon- potassium fertilization for leaves is studied. The Pb concentration has decreased in the chestnut leaves in 14 times, Cd concentration – in 2 times. Cd concentration in the linden leaves has decreased in 2 times, Pb concentration – in 1.9 times. In the linden flowers the Cd concentration has decreased in 2.5 times.
