Abstrak
Tuproq eroziyasi O'zbekistondagi asosiy ekologik muammolardan biri bo'lib, ta’sir ahamiyati bo'yicha sho'rlanishdan keyin ikkinchi o'rinda turadi. Mamlakat yarim qurg'oqchil iqlimga ega va yog'ingarchilikning kamligi bilan ajralib turadi, bu esa o'z navbatida tuproqning degradatsiyasi va eroziya jarayonlarining rivojlanishiga yordam beradi. Taxminan 800 ming gektar lalmikor yerlar va mamlakatning umumiy qishloq xo'jaligi yerlarining qariyb 15 foizi turli darajada tuproq eroziyasiga uchragan. Bundan tashqari, yaylovlardan noto‘g‘ri foydalanish va samarasiz sug'orish usullari kabi beqaror qishloq xo'jaligi amaliyotlari muammoni yanada kuchaytiradi.
