It is shown the average humus content in agricultural soils of different soil and climate zones of Ukraine. It is emphasized that today there is a positive trend in the humus content of soils in comparison with the data of previous years. The existing resources of organic raw materials for replenishment of organic carbon reserves in the soils of different zones of Ukraine have been analyzed. The characteristics of potential resources of organic raw materials of natural origin and organic waste from the standpoint of humus formation are given. Approaches to the management of organic materials to increase the efficiency of accumulation of humus in soils are proposed. In a model experiment, it is proved that humus of alluvial-meadow soils is easy to be mineralized in comparison with chernozem soils. Taking into account the peculiarities of meadow soil formation, approaches to carbon budget conservation in these environmentally sensitive soils are proposed.
