Change the settings for long-term use of fertility sod-podzolic soils of arable |
|
|
Arable sod-podzolic soils are inherently characterized by a number of properties inherited from the original virgin and partly acquired present soil under the influence of human activities. In arable soils vary significantly hydrothermal conditions, the biological cycle of nutrients, which is associated with a significant alienation from their yield and return with mineral and organic fertilizers. Prolonged use of mineral and organic fertilizers in combination with periodic liming as at permanent cultivation of field crops, and in the rotation, increases sod-podzolic light loamy soil cultivation grade that provides a stable yield of winter cereals at 4.5-5.5 t / ha of grain, 20-25 t / ha of potatoes and 6-8 t / ha of perennial grasses hay while reducing the extent of soil degradation to environmental standards.
