The Effect of Land use and Soil Erosion on Soil Organic Carbon and Nitrogen Stock
Soil organic carbon (SOC) is a principal component in soil quality assessment. Knowledge of SOC and total nitrogen (TN) stocks are important keys to understand the role of SOC in the global carbon cycle and, as a result, in the mitigation of global greenhouse effects. SOC and TN stocks are functions of the SOC concentration and the bulk density of the soil that are prone to changes, influe...
متن کاملMultiscale Soil Erosion Simulations for Land Use Management
Increasing pressures on the land and an improved understanding of human impacts on the environment are leading to profound changes in land management, with emphasis on integration of local actions with watershed-scale approaches. This trend has a significant impact on the development of supporting GIS and modeling tools. Complex, distributed, physics-based models are needed to improve understan...
متن کاملLAND USE: U.S. Soil Erosion Rates--Myth and Reality.
No problem of resource or environmental management can be rationally addressed until its true space and time dimensions are known. The limitations of the universal soil loss equation and the wind erosion equation are such that we do not seem to have a truly informed idea of how much soil erosion is occurring in this country, let alone of the processes of sediment movement and deposition. The un...
متن کاملThe impact of sound land use management to reduce runoff
The study aimed to determine the impact of sound land use management to the runoff in Kabuntalan, Maguindanao in Tamontaka river basin. This was done through simulation and the comparison of the three land cover scenarios such as 2015 land cover, 2025 projected land cover and desired land use to determine its difference in terms of runoff. Hydrologic Engineering Center-Hydrologic Modeling Syste...
متن کاملPredicting soil erosion for alternative land uses.
The APEX (Agricultural Policy-Environmental eXtender) model developed in the United States was calibrated for northwestern China's conditions. The model was then used to investigate soil erosion effects associated with alternative land uses at the ZFG (Zi-Fang-Gully) watershed in northwestern China. The results indicated that the APEX model could be calibrated reasonably well (+/-15% errors) to...
