The aim of this work is to test the technology of application of multifunctional microbial compounds on corn in the zone of unstable moistening of the Central Ciscaucasia. The object of research are microbial complex composites. The studies were conducted on ordinary chernozem soil. According to the traditional technology we treated the seeds before sowing and corn plants in the phase of 3-4 leaves and flowering, and for the further improvement we treated the soil before sowing. It was revealed that the smallest number of micromycetes and cellulosolytics appears in the phase of 3-4 leaves. The use of bioproducts had no significant effect on the number of microorganisms during this period. The number of the studied microorganisms has increased in the flowering and milky stages, and especially due to the use of compounds. The study of corn yield revealed that the least yield was in the control experiment and made up 4.07 t/ha. Application of the CBC-Standard product increased the yield by 0.98 t/ha in traditional technology. The lowest increase of 0.43 t/ha was observed on the variant with application of “CMC-92”. On the proposed technology with the variant with application of “CMC-92”, the corn yield was the highest and amounted to 5.35 t/ha. It is higher than in the control experiment by 1.28 t/ha.
