The erosion processes are strongly expressed on arable land in sloping areas in our country. They are typical for soils with light mechanical content and a slope greater then 8% rain, and for the same soils for greater than 3% slope using gravitation watering. The present work considers the factor that costs the erosion. Some methods to reduce the soil loses are discussed. The crop was maize. The erosion under irrigation is one of the ecological problems in agriculture.
