Ameliorative improvement of degraded irrigated lands in the south of Kazakhstan using chemical reclamation

The article presents studies of energy-efficient use of chemical reclamation on degraded irrigated lands of the Republic of Kazakhstan. According to the research results, it has been revealed that the combined use of certain chemical reclamation technologies provides a favorable salt regime of the soil and obtaining high yields of corn grain with savings of fuel and energy resources. When carrying out chemical melioration on irrigated degraded lands using water-saving irrigation technologies and adding mineral and liquid chemical meliorants: phosphogyp-sum (CaSO₄ꞏ2H2O)+aqueous ammonia (NH₃+NH₄OH) (phosphogypsum dose 5 t/ ha+aqueous ammonia dose 50 kg/ha, concentration 25%) - in the root zone, a decrease in toxic salts and an increase in non-toxic ones are ensured. This generally leads to an improvement in the condition and productivity of such lands, so the yield of corn grain in this research option exceeded the control option with discrete and drip irrigation, respectively, by 20.7-20.9 c/ha.
