Abstract

In this article, changes in the concentration of CO2 released into the atmosphere from irrigated gray-earth, gray-earth, meadow-gray-earth, meadow-swamp and marsh soils on the I-V terraces of the Chirchik River in the Yangiyul district of the Tashkent region were studied using 5-point measurements of soil types on each terrace, air and soil temperature measurements, CO2 range, density (press 3 minutes) is being studied. The results showed that on moisture-rich marsh, meadow, and meadow⁻gray-earth soils, CO2 emissions were high (775-1114 ppm/mmol mol-1), and on gray-earth soils, they were lower or moderate (550-766 ppm/mmol mol-1). The results showed that CO2 emissions were high (775-1114 ppm/mmol mol-1) in wet swamp, meadow, and meadow⁻gray soils, and lower or moderate (550-766 ppm/mmol mol-1) in gray soils.
