Role of soil biota in the formation of soil fertility in agricultural landscapes of Akmola region, Kazakhstan

Biofertilizers are needed to restore soil fertility. Long-term use of chemical fertilizers causes soil degradation and affects crop yield. Biofertilizers increase the soil's water-holding capacity and add nutrients like nitrogen, vitamins, and proteins to the soil. This article, with the topic of agricultural land use, deals with the impacts of control operations on the living part of the soil and its processes that play a role in the biological fertility of the soil. This article evaluated the effect of cultivation rate and biota on the fertility of agricultural lands in the Akmola region, Kazakhstan using soil analysis under different conditions. Although physical, chemical, and biological factors are generally recognized as the most important factors of soil fertility, more attention has been paid to the management of the physical and chemical parts of the soil compared to the biological part. The results show that soil microbial biomass causes many chemical changes in the soil. Therefore, microorganisms have a major controlling role in the cycling and loss of nutrients from the soil. They also regulate the availability of nutrients and many other transformation processes in the soil.
