1. Soil Carbon and Nitrogen Distribution and Gaseous Flux Due to Landscape Position and Temperate Alley-Cropping Practices in an Agricultural Watershed

Soil NzO and COz efflux can be stimulated by agricultural practices whlch may contribute to an enhanced global warming effect. However, the efflux of these two gases in response to landscape position and soil conservation management practices such as contour strips in a temperate agoforestry alley cropping system has not been extensively studied. The objective of this study was to assess the effects of alley cropping and landscape position on soil total organic C and total N distribution and N20...
