Carbon reserves on the soils of the Dmitrievsky village council of the Ufa district of the Republic of Bashkortostan

Abstract

The research was carried out within the framework of the state task of the Ministry of Education and Science of the Russian Federation “Program for the creation and operation of a carbon landfill in the Republic of Bashkortostan “Eurasian carbon landfill” for 2022-2023 (Publication number: FEUR-2022-0001). Carbon deposition in the soil is an essential function arising from the interaction of ecological processes. Human activity influencing these processes leads to dehumidification or, conversely, deposition of soil carbon. The article presents the materials of the analysis of literary sources on the subject of carbon farming, as well as the content of organic matter in the soils of agricultural lands of the southern forest-steppe of the Republic of Bashkortostan in the conditions of a carbon landfill in the Ufa district (Russian Federation). This study aims to analyse carbon reserves in the humus-accumulative soil horizon of a carbon landfill on agricultural lands in the Dmitrievsky Village Council of the Ufa district of the Republic of Bashkortostan. An agrochemical analysis of the accumulation of soil organic matter was carried out, and the capacity of the humus horizon of the soils of this site was determined. Carbon reserves in the studied soils were determined according to the methodology for quantifying greenhouse gas emissions and uptake [Order of the Ministry of Natural Resources of Russia No. 371 dated 05/27/2022, Guidelines for Quantifying the volume of greenhouse gas uptake]. The carbon content in the organic matter of soils is assumed to equal 58%. The conversion to the stock of soil carbon was carried out, considering the density of the soil composition. The degree of saturation of the soils of the studied sites, including the carbon landfill, is calculated. The reserves of organic carbon under individual varieties of soils in the humus-accumulative horizon - 4616360 tons were estimated.
