Effects of Different Methods of Treatment on Soil Before Sowing on the Change of Agrophysical Properties of Soil and Crop Yield

Abstract

According to the article, agro-technical measures are carried out using a combination of aggregates to a depth of 35-40 sm, sowing cotton at a height of 30 sm at a time, winter wheat, and then cotton at a depth of 35-40 sm for the cultivation of secondary crops. Apply mineral fertilizers without liquid ammonia in the amount of 100 kg / h, the annual norm of mineral fertilizers under the piles, along with the removal of piles at a height of 30-35 sm. For winter wheat and repeat crops, the minimum method is to cultivate at a depth of 10-12 sm, to cultivate cotton at a depth of 35-40 sm, to take a pile at a height of 30-35 sm at a time, to make a pest 30-35 sm below the annual norm of mineral fertilizers 100 kg In the case of liquid ammonia in the amount of the remaining 100 kg / h in the form of ammonium nitrate in the form of ammonium nitrate, depending on the volume, porosity and water permeability of the soil.
