The soils of the experimental field of the Vereshchagin Vologda State Dairy Farming Academy and their agrochemical characteristics

The paper characterizes the soil cover of the Vereshchagin Vologda State Dairy Farming Academy experimental field. As a result of a long-term agricultural use virgin sod-podzolic soils were significantly transformed into agricultural sod-podzolic soils. Their profile includes agricultural humus (arable) horizon - 20-25 cm, alluvial - 6-8cm, suballuvial - 12-13 cm, textured (illuvial) - 44-50 cm. The soilforming rocks are soil cover loams, the soil particle size distribution prevailing in the arable layer of soil is light and medium loamy. The soils under study have an average humus content, a slightly acid medium, an increased base saturation, a very high mobile phosphorus content and a medium potassium content (according to Kirsanov). The arable layer has an average content of mobile forms of boron, copper, zinc, manganese and a low content of molybdenum. On the basis of soil and agrochemical monitoring some measures to maintain and increase the agricultural sod-podzolic soils fertility have been suggested.
