Description
Summary:The study is focused on assessing the carbon sequestration depending on the methods of soil enrichment with organic materials. The level of additional sequestration in soils must be determined by taking into account the costs of net primary (NPP) and ecosystem (NEP) production of photosynthesis by the amount of the new additions of the mineralization-resistant organic carbon: net biome production (NBP) . The stock of carbon into easily mineralizable forms of NEP determines the short-term sequestration of carbon. Medium- and long-term sequestration includes the accumulation of carbon in the soil in the NBP pool. The transformation of organic carbon in the system of NPP→ NEP →NBP pools is a long process of humification, which is accompanied by a loss of carbon (CO 2 ) into the atmosphere.
