Effects of deep softener and chemical compounds on mechanical compositions in heavy, difficult-toameliorate soils

Аннотация

The article deals with deep loosening of heavy, difficult-to-ameliorate, gypsum, medium salinity soils in the conditions of Bukhara region, as well as high-quality saline washing and watering of saline soils using a chemical reclamation (Spersal) compound. Significant water savings were observed during the harvest, and the control of dry residue and chlorine ions was reduced in the remaining variants, in addition the results of the study to the effect of the Bukhara- 102 variety of cotton on the amount of salts in the soil by irrigating are presented. In this case, the cotton is cultivated without deep loosening of the soil with the variant of direct cultivation of the soil with a deep softener, softening at a depth of 60 cm and 80 cm, and irrigation of the (Spersal) compound, drainage, the effect of soil salinity on fertility and water permeability was analyzed
