NORMALIZATION OF FERTILIZER IN IRRIGATIVE SOIL SUBJECT TO EROSION

Аннотация

The article talks about the rationing of fertilizer for special types of repeated crops, wheat and cotton on a typical soil that has undergone irrigation erosion, as well as the adaptation of water measurement. Today, 12.3% of the world's arable land is irrigated land, where most of the food is grown. There are now 1.094 million people in the world. ha or 56% of the irrigated area. Most of the eroded areas are located in Asia, Africa and South America [1]. Specifically, 81% in Australia, 74% in Central America, 63% in North America, 50.6% in South America, 52% in Europe, 59.0% in Asia and 46.0% in Africa were affected. In addition, due to irrigation erosion worldwide, $ 75 billion is lost annually to agriculture. tons of topsoil is lost [2]. The area of ​​eroded land in the country is 1772.3 thousand hectares, or 40% of the total arable land. In these areas, the yield of cotton, winter wheat and other crops is 20-30% lower than on non-eroded lands, and the quality of the raw materials grown is low
