Abstract
The paper presents a regional statistical characteristic of the analytical and morphometric properties of the prevailing light gray forest agrogenic soils and the dynamics of the yield of winter rye. It has been established that the balance is generally positive, with a phosphorus content of plus 15.4 kg, nitrogen - plus 4.7 kg, negative potassium - minus 16.5 kg. The example of background zonal light gray forest soils shows changes in the agrochemical state due to economic activity. The noted regularity affects the dynamics of the yield of the winter rye of the region. The actual yield of winter rye rises from the beginning of observation to the last years, with a maximum of 31.9 c / ha. At the same time, in recent years there has been a tendency to reduce the yield of all crops, including winter rye. The noted decrease in the yield of winter rye in the region is recorded by its moving averages over 11 and 22 years, which is due to the negative balance of macroelements in agriculture during this period.
