Features of the structure of forest soils in spruce stands of Udmurtia

The article presents the data of studies of the state of forest soils under spruce stands. The research was carried out on the territory of the Udmurt Republic in the most common types of forest – spruce forests. To assess the soil horizons, soil sections were laid, chemical analysis of the soil was carried out, by determining the main indicators, such an important element of forest soils as forest litter was analyzed. It was revealed that the dark coniferous forests of the republic were formed on sod-podzolic soils. These soils are characterized by an acidic reaction of the soil solution and a low content of basic nutrients. In the context of the development of transport infrastructure, a high content of potassium (225 mg/kg or more) is observed due to the use of KCl as an anti-icing reagent. Soil acidity varies from highly acidic (3.9 pH) to acidic (4.9 pH), due to the influence of coniferous plants. In turn, this can negatively affect the state of the spruce stands.
