Sug'oriladigan tuproqlarning unumdorligini oshirish muammolari

The article describes the decline in soil fertility from year to year as a result of soil erosion, degradation and dehumification, which is caused by non-compliance with crop rotation, lack of organic fertilizers, unilateral use of high doses of nitrogen fertilizers.
