WebFeb 13, 2024 · The grasslands in the tropics are estimated to take up about 0.5 picograms (Pg) of C annually, which is influenced by the baseline soil organic carbon (SOC) level as well as annual precipitation [4,5,6]. Moreover, grassland soils store 200–300 Pg carbon, which significantly influences the global carbon cycle . WebOct 24, 2024 · Native and improved pastures are two types of land use that retain carbon in the soil. These land uses usually cause little soil disturbance, which reduces the carbon loss from organic matter and allows fresh plant materials from the grasses to become part of the soil organic matter over time. WebMar 7, 2024 · Grassland ecosystems cover a large portion of Earths’ surface and contain substantial amounts of soil organic carbon. Previous work has established that these soil carbon stocks are sensitive to management and land use changes: grazing, species composition, and mineral nutrient availability can lead to losses or gains of soil carbon. cityengine中文设置
