But an overloaded agricultural system has depleted the land's carbon content and its replenishment is vital in the face of climate change.
This study has investigated the variations in selected soil properties (soil textural fractions, bulk density, soil moisture content, pH (H2O) and soil organic carbon content) under two land use types: open grazing land and exclosures in the Central Rift Valley of Ethiopia.
We also gather information on five covariates (elevation, soil organic carbon content, road density, land cover and population density) which might influence POP concentrations.
In this study, soil organic carbon (SOC) content and organic carbon density were estimated based on a soil survey of a small landscape in Dongguan, South China, with spatial heterogeneity of SOC distribution and the impacts of land-use patterns on soil organic carbon content assessed.
In a statement, Kellogg's said that it will require its suppliers to "protect forests, endangered species habitat, lands with high carbon content, and peatland of any depth.
The result is in agreement with Mekuria and Veldkamp (2005) in that grazing land and exclosure differ considerably in their soil organic carbon content reflecting the higher amount in exclosures than in open grazing land.
Although the natural savanna land cover system was within the Yongka Garden Park, the results showed that the soil was low in soil organic carbon content compared to those under the natural forest cover.
At low altitude, the soils under natural forest and those under natural savanna land cover systems had the highest mean soil organic carbon content (3.10%) followed by soils under E. saligna plantations (3.05%) (Table 4).
At high altitude, the soils under natural forest land cover system (protected forest) had the highest mean soil organic carbon content (6.50%) followed by those under E. saligna plantations (5.79%) (Table 4).
