The paper reports the results of a study conducted in 2023 in the Baltabai rural district, Yenbekshikazakh district, Almaty Region, Kazakhstan. The study centered on analyzing soil samples collected as part of field experiments. The research goal was to assess the influence of various organic farming technologies on soil microorganisms, such as bacteria, fungi, and actinomycetes. The results proved highly significant for microbiological research as they highlight the effect of various environmental conditions on the growth and development of microorganisms. The study reveals that using organic farming technology in the combination of winter peas and corn as a cover crop promotes a higher concentration of bacteria than traditional cultivation methods. Cultivating soybeans with organic agriculture resulted in the highest levels of bacteria. Cultivation of winter peas for green mass, its use of soybean cover in organic agriculture, and their variants becoming straw as organic fertilizers helped increase actinomycete concentration. It proved that Gauses agar, Ashbys medium, and meat-peptone agar provide optimal conditions for the growth of bacteria. Meanwhile, Czapek-Dox and Hutchisons media do not support their growth at specified dilution rates. Actinomycetes fruitfully multiplied in Gauses and Hutchisons media at the 10^-3 dilution rate. Ashbys medium, meat-peptone agar, and starch ammonia agar at the dilution rate of 10^-5 showed no positive effect on the growth of fungi, while Czapek-Dox, Gauses, and Hutchisons media diluted at the rate of 10^-3 provided optimal conditions for soil fungi production. The findings of this study can find practical applications in quality control and safety assurance in medicine, food production, and agriculture.
