Objective. To study the efficiency of inoculation of seeds by biological preparations under in-fluence on humus balance in growing crops in short crop rotation. Methods. Field, laboratory, cal-culation-comparative. Results. It was found that the highest entrance of organic matter in the soil was due to the use of organo-mineral fertilizing system NPK-manure-green manure, which contrib-utes to the increase of organic carbon reserves by 17.4 t/ha without the use of microbial prepara-tions and by 18.0 t/ha against the background of microbial preparations in comparison with the mineral fertilizing system. The use of microbial preparations under the fertilizing systems NP-manure-green manure allows to increase the amount of organic matter entering the soil by 1.2 and 1.6 t/ha during crop rotation. Under the use of organic fertilizers (manure, green manure) in com-bination with mineral ones and seed inoculation, not only the recovery of fertility of sod-podzolic soil, but also increase in the content of humus within the limits of 0.43–0.53 t/ha is reported. The use of manure on the background of the NPK makes it possible to increase the humus reserves in the soil by 0.11 and 0.15 t/ha per year. During crop rotation, the amount of newly formed humus in this variant exceeded its mineralization loss by 0.42 t/ha without microbial preparations and by 0.58 t/ha on the background of microbial preparations. Conclusion. The positive effect of the use of biological preparations under inoculation of seeds in combination with the organo-mineral fertiliz-ing system on the content of humus in sod-podzolic soil on average by crop rotation was estab-lished. Organic-mineral fertilizing system (NPK + manure + green manure) provides the highest growth of humus reserve in soil — 0.53 t/ha per year. The use of microbial preparations in the cul-tivation of crops under this fertilizing system contributes to the increase of humus content in the soil by 0.16 t/ha during crop rotation.
