Provides a comparative analysis of forest fertility of sod-podzolic soils on glaciofluvial and glacial sands under pine forests the different subzones of the forest zone of Ukraine - Eastern and Central Polessye. It was determined that the overall level of fertility of sod-podzolic soils of East Polissye increased in comparison with the Central. The increase in soil fertility caused by increase in the proportion of fine sand and clay particles, as well as an increase in the content of total phosphorus and potassium. Acidity and nitrogen content in the soil of subzones virtually unchanged. The humus content is a little more in the soils of the Central Polessye. We analyzed the change in the productivity of pine forests, depending on the level of soil fertility. The increase in soil fertility in East Polessye becomes the cause increased productivity of pine forests. This increases the proportion of pine with high productivity (II quality class and higher) and a decrease in the proportion of plants with low productivity (III grade quality and lower).
