The biological activity of the soil is formed mainly due to the microbiota living in it. In this regard, when creating agricultural technologies, the properties of microorganisms are widely used to increase the biological activity of the soil and reproduce soil fertility. Harmoniously functioning soil largely determines the nutritional properties of the agricultural products produced on it, which takes the corresponding technologies from the category of regenerative to health-saving technologies. Considering that soil microorganisms play an important role in the transformation of substances in the soil, the influence of the bio-organo-mineral complex AKM on the intensity of substrate-induced soil respiration in the near-root zone of trees was evaluated to assess the degree of bioactivity. A positive effect of AKM on the growth of chlorophyll content in apple tree leaves has been established. The beginning of the increase is observed 33 days after the application of fertilizer and in subsequent periods this trend continues. The obtained results confirm the existence of a relationship between chlorophyll concentration in leaves and productivity. Based on the data of the experiment, we can conclude that the bio-organo-mineral complex AKM is a means of soil bioactivation. This is expressed in an increase in soil respiration during the growing season by 8.8-45.5 %. The magnesium contained in the complex provides an increase in suction power due to an increase in the concentration of chlorophyll (4.8-36.5 %) and the intensity of photosynthesis, which ultimately leads to an increase in the availability of mineral nutrients associated with fruit trees. As a result of the action of A�M, fruit yield capacity increases by 14.3 %, and their quality also increases. The importance of using magnesium fertilizers, in particular AKM, is associated not only with the ability to increase crop yields, but also with the ability to produce physiologically more valuable products in terms of nutrient content, which can be used in health conservation programs for the prevention, including endemic diseases of the population.
