BIOLOGICAL ACTIVITY AND EMISSION OF CARBON DIOXIDE FROM DARK CHESTNUT SOIL OF WESTERN KAZAKHSTANNurlan Sergaliyev, Aliya Nagiyeva and Anvar Tlepov
Steppe ecosystems of the arid region of Western Kazakhstan are widely used in agricultural production. Therefore, it is important to study the emission of carbon dioxide from agricultural soils. The authors studied seasonal and annual emissions of carbon dioxide from the agricultural soil of Western Kazakhstan. The difference in the most active emissions recorded in late spring with a gradual decrease in the summer period is reflected in the obtained results over the years. The reason for this was a very hot summer with amoisture deficit, which affected the rate of carbon dioxide emission.
