Phytomass Heracleum Sosnowskyi and the Rate of Its Decomposition in the Soils of Postagrogenic Ecosystems of the Middle Taiga Subzone of the Komi Republic
Year: 2024
Type: conference-paper
Abstract: The dynamics of decomposition of Heracleum sosnowskyi and dominant plant species of a grass meadow in a laboratory experiment is considered. Samples of the humus-accumulative horizon of the postagrogenic sod-podzolic soil of the Komi Republic were used as a substrate, the exposure time was 75 days, the ambient temperature was +5 ° C, the substrate humidity was 60% of the total moisture capacity of the soil. It is shown that under the controlled experimental conditions, various parts of Heracleum sosnowskyi plants lose up to 43-44% of the initial dry phytomass during the exposure period, and meadow cereals – up to 18-29%. The main part of the loss of phytomass falls on the first 28 days of exposure. For the aboveground part of plants, it is 70-78% of the total loss of plant mass, for the underground part of plants – 47-51%.
