Methane and Nitrous Oxide Emissions from Cattle Excreta on an East African Grassland.

abstract：:Stormwater infiltration basins, one of the typical stormwater best management practices, are commonly constructed for surface water pollution control, flood mitigation, and groundwater restoration in rural or residential areas. These basins have soils with better infiltration capacity than the native soil; however, th...
