Seasonal Activity of Soil Peroxidase in Drained Swamp Pine Forests of Western Siberia: Systemic-Ecological Analysis
AbstractWe studied a mesotrophic swamp drained 25 years ago in the northern part of the Ob’ River basin (56°23′710″ N, 84°34′043″ E). In peat soils...

Map** and monitoring peatland conditions from global to field scale
Peatlands cover only 3–4% of the Earth’s surface, but they store nearly 30% of global soil carbon stock. This significant carbon store is under...
