The purpose of research is to determine the intensity of CO2 emissions from sod-podzolic soil under the influence of various anthropogenic loads. To study the peculiarities of carbon dioxide emission from the soil during the cultivation of crops in crop rotation under different systems of fertilizers and liming. As a result of the conducted researches the adaptive technologies of application of different doses and types of chemical ameliorants against the background of fertilizer and their influence on carbon dioxide emission on sod-podzolic soil in short-rotation crop rotation in the conditions of Western Polissya are improved. Determining the amount of CO2 emissions from the soil in field agroecosystems, establishing its dynamics during the growing season will predict changes in the productivity of agrophytocenoses on the basis of the following conclusions: According to the results of research it is established that the emission of carbon dioxin and its dynamics depend on fertilizers and chemical ameliorants during the growing season, both in spring barley on the background of N90P90K90 and 1.5 doses (Ng) of CaMg (CO3) 2 with fertilizer, these figures increased to 68 , 6–89.8–63.5 mg СО2 / kg of soil and 65.9–98.2–72.2 mg СО2 / kg of soil. In the winter wheat field, carbon dioxide emissions were highest at 1.5 doses (Ng) against the background of N120P60K90 in the tube exit phase and amounted to 77.7 mg CO2 / kg of soil at an air temperature of 13.2 ° C, with an increase in air temperature to 22 , 0 ° C in the earing phase, this figure increased 1.2 times, while in the phase of full maturity at an air temperature of 20.4 ° C decreased 1.3 times.
