A system of normative indicators for forecasting and assessing ecological and economic losses as a result of erosion processes

Abstract

The results obtained both in field hospitals and in the course of route studies made it possible to develop standards for the loss of batteries, which depend, first of all, on the degree of erosion degradation of soils. The decrease in humus content varies in the range of 5–15 % on slightly eroded soils, medium-eroded – 15–30 %, strongly eroded – 30–40 %. Losses of mobile phosphorus and potassium on slightly eroded soils are found in the range of 10–20 %, medium-eroded – 20–30 %, highly eroded – 30–50 %. Based on the assessment of yield shortfalls from erosion degradation, all crops are grouped according to the degree of resistance to water erosion processes as follows: high – annual grasses, perennial grasses; medium – winter and spring cereals, winter and spring rape, flax, sugar beet; low – corn.
