The article deals with the influence of big ungulates on the quantitative changes in the amount of soil nitrogen. The experiment on collection and computation of solid excretions of two main ungulate populations in two dominant parcels on the investigated territory was held. Sampling and analyses of soil (under the ungulates` influence and without it) were held every half-year (in spring and autumn). The dynamics of soil nitrogen concentration during 3-year-influence of deer and fallow-deer is shown. Statistic computations and analyses of the data were made.
