In 430 mkn.ha of land has been damaged by erosion processes in Ä?ÅÄ«Ä?rÄ?nÆ? countries around the world. Surface, cleavage and ÅrrÅÅÄ?Æ?Žn erosion is also widespread throughout the country. 43.29% of the total area is subjected to varying degrees of erosion. In some regions, especially the Nakhchivan AR, erosion processes cover 70% of the area. 66.6 of the total area of the southern slope of the Greater Caucasus has been eroded. In some areas of the country, the percentage of eroded farms is high. This Ä®ÅƵrÄ? is 51% in Lachin-Kalbajar zone, 57.9% in Guba-Khajmaz zone and 72.4% in Sheki-Zagatala. The newly formed splinters break down the farmland into small parts and make them useless. The following erosion intensity scale is presented. 1) net wash-up to 0.5 t / ha, 2) poor wash-up to 0.5 t / ha, 3) moderate washing 1-5 t / ha, 4) severe washing -5-10 t / ha, 5) very severe washing -10 t / ha. ÅÄ«Ä?rÄ?nÆ? geographical areas of the country have also been ÅÄ?Ä?nÆ?Ä®Ä?Ä? the possible distances between stripes on Ä?ÅÄ«Ä?rÄ?nÆ? slopes. Soil Æ?rÄ?Æ?Ä?rÄ?Æ?Žn should be carried out with a strip of 1–2 m in every 3–5 m in areas of 10–200 incidence, moderate to severe, and 1.5–3 m wide in each of the 2–3 m in severely washed areas of 20–300 m. trench to be dug. In large areas with more than 15-200 thick, thick soils and where the tractor can operate, Ä?Ä?ĨŽrÄ?ÆÆ?Ä?Æ?Žn should be carried out on terraces. On the slopes where heavily washed and ŽÅ?Ä?n rigid rocks are exposed, soil Æ?rÄ?Æ?Ä?rÄ?Æ?Žn can be used to make yards and ditches.
