QISHLOQ XO‘JALIGIDA ORGANIK CHIQINDILARNING ORGANIK MODDALARGA AYLANISHI.
Abstract
Ma”lumki, O‘zbekiston hududidagi sug‘oriladigan yerlarning unumdorligi pasayib bormoqda. Bunga quyidagilarni asosiy sabab qilib ko‘rsatish mumkin: mineral o‘g‘itlarning organik o‘g‘itlar (go‘ng, gumus) ga nisbatan ko‘p qo‘llanilishi, yerga intensiv ishlov berish, begona o‘tlarga qarshi turli xil pereparatlardan foydalanish va boshqalar.
