METHOD FOR DETERMINING TOTAL LOSS OF CARBON AND INTEGRAL EMISSION OF CARBON DIOXIDE DURING DRAINAGE OF SWAMPS Russian patent published in 2023 - IPC G01N33/24 

FIELD: agriculture.

SUBSTANCE: invention relates to the reclamation of swamps, ecology and agromeliorative use of natural resources. The method for determining the total loss of carbon and the integral emission of carbon dioxide during the drainage of swamps includes monitoring changes in the thickness of the peat deposit and its properties during drainage of the swamps, carried out by standard measurements of the thickness of the peat deposit for reclamation surveys: drilling wells, laying reference plates on the predicted base of the transformed peat layer, sampling of peat with an undisturbed structure using the cutting ring method at representative reference points, determining the density of the peat deposit and the carbon concentration in it, ash content and other water-physical and agrochemical characteristics of the transformed peat layer to a depth of at least 1 m with a time interval of 5 or more years, followed by carrying out a comparative analysis of data from the initial and subsequent moments of time, on the basis of which the loss of peat mass during drainage is determined, characterized in that they carry out a planned and altitude binding of reference points, the loss of peat mass during drainage is determined by the formula: L=10⁴(Δ₀-Δ₂)γ₀, where L is the loss of peat mass, t/ha, Δ₀ and Δ_z is the shrinkage of the day surface and the bottom of the transformed peat layer, m; γ₀ - density of undrained peat, t/m³; the total carbon losses during drying are determined by the formula: L_C = C_CL(1-D_as), t/ha, where C_C is the fractional coefficient of carbon concentration in the organic matter of peat, fractional units; D_as is the degree of ash content of peat, units, and the integral emission of carbon dioxide is determined based on the chemical formula of carbon dioxide according to the formula: E_CO2 =3.67 L_C, t/ha.

EFFECT: obtaining more accurate data on the total time loss of carbon from drained peat-bog soils and the integral emission of carbon dioxide at lower material costs, which will make it possible to more reasonably establish environmental risks, optimize the reclamation regime and technologies for the agricultural use of peat-bog soils.
