WebDec 29, 2024 · Global grasslands store 10–30% of soil organic C (SOC) and harbor more than 10% of terrestrial biomass C (Follett and Reed 2010; Scurlock and Hall 1998 ). In the context of increasing atmospheric CO 2 concentration, grasslands are considered to be potential C sinks under proper management (Lal et al. 2007 ). WebThe soil carbon (C) dynamics is strongly influenced by climate and land-use patterns in the Himalayas. Therefore, soils under five prominent land use [e.g., maize (Zea mays), horticulture, natural forest, grassland, and wasteland] were sampled down up to 30 cm depth under two climatic conditions viz., temperate and subtropical to assess the impacts …
