Soil Erosion in Large Slopes and its Prevention Measures

Abstract

This article ramp largest irrigated heavy, medium and light soil and water erosion lands through the application of new technical means and technologies developed measures to reduce the erosion of the furrow irrigation. In particular, information will be provided on how to achieve high and quality yields of agricultural crops, including cotton, through the identification of elements of water-saving irrigation techniques.

At present, out of the total area of ​​44797.7 thousand hectares, 27521.6 thousand hectares are used in agriculture, and 4238.6 thousand hectares are irrigated lands. They are located in agricultural areas with different natural soil-climatic conditions, and intensive farming is carried out mainly on 4278.0 thousand hectares of irrigated land, where the reclamation, ecological status and level of soil fertility differ sharply. Unfortunately, the reclamation situation in 65.9% of these areas is unsatisfactory, 1.5 mln. more than 0.7 million hectares to deflation. hectares are strongly deflated, 660,000 hectares are irrigated, 40,000 hectares are jar eroded, and there is a steady decline in soil fertility in irrigated agriculture.

Clear recommendations and conclusions are given on the method used to prevent soil leaching.
