BACKGROUND AND AIMS Soils of mountain regions and their associated plant communities are highly diverse over short spatial scales due to the heterogeneity of geological substrates and highly dynamic geomorphic processes. The consequences of this heterogeneity for biogeochemical transfers, however, remain poorly documented. The objective of this study was to quantify the variability of soil-surf...

A study was conducted in the alluvial soils located in Oko-anala in Delta State, Nigeria. These alluvial soils are primarily used for intensive vegetable production for commercial purposes. The total land area of about 3.34 Square kilometer was divided into three consociations and composite soil samples collected from pre-determined depths of 0-15 and 16-30cm. The samples were routinely prepare...

retention in alluvium-derived soils of headwater ephemeral streams. Zuni farmers of western New Mexico demonstrate knowledge Peterson et al. (2001) create a convincing case for about soil and hydrological processes that link upland watersheds to alluvium-derived soils that have crucial cultural, ecological, and conservation that maintains or restores the storage cahydrological functions. To def...
