Abstract
Purpose
This study aims to assess the spatial distribution of carbon reserves in the surface of organic and mineral soil layers, in a carbon landfill. The studied areas are located within the broad-leaved forests of the Southern Urals.
Methods
The analysis of the forest carbon cycle was conducted in early spring on trees, shrubs, and grass vegetation. Soil gas flux measurements were performed using a Smart Chamber connected to a LI-COR 7810 gas analyser. CO2 flux emission from the soil surface reached up to 493.2 Gf a day, under the tree canopy and did not exceed 471.8 Gf in uncovered areas (glades).
Results
Thus, in early spring, the CO2 flux emissions from the soil surface in forest stands is higher in absolute terms, than in uncovered areas. It can presumably be explained by the difference in vegetation cover, along with the size, depth, and spatial distribution of roots from trees, shrubs and herbaceous plants.
Conclusion
Forest litter and humus, mainly composed of potassium, nitrogen, and phosphorus, are critical for maintaining the carbon balance in forest areas.
期刊介绍:
The Journal of Soils and Sediments (JSS) is devoted to soils and sediments; it deals with contaminated, intact and disturbed soils and sediments. JSS explores both the common aspects and the differences between these two environmental compartments. Inter-linkages at the catchment scale and with the Earth’s system (inter-compartment) are an important topic in JSS. The range of research coverage includes the effects of disturbances and contamination; research, strategies and technologies for prediction, prevention, and protection; identification and characterization; treatment, remediation and reuse; risk assessment and management; creation and implementation of quality standards; international regulation and legislation.
