The USDA Natural Resources Conservation Service (NRCS) developed the Mississippi River Basin Healthy Watersheds Initiative (MRBI) program to improve the health, water quality and wildlife habitat within the Mississippi River Basin. Lake Conway Point Remove (LCPR) watershed was identified as one o...

Experimental sites were selected within Dembala Wacho ranch which lies in the central part of Sidamo, and this report describes these sites together with the first findings on the status and turn-over of minerals in the system. The three sites have consequently been located according to tree and ...

In this chapter, it is argued that the application of scientific knowledge is an essential prerequisite for sustainable resource management. Scientific inputs have the following components when applied to a specific region: (1) a through analysis of the resource base, with emphasis on feed and wa...

Temporal and spatial variabilities in rainfall, herbaceous production and biomass were studied over a 4-year period in a topographically diverse, arid pastoral region of northwest Kenya. A significant relation between rainfall and primary production was found, and this was applied in a manner tha...

The contribution of the cover crops Mucuna pruriens var. utilis and Pueraria phaseoloides to the N balance of a sole maize relay cropping system was estimated. Over 4 consecutive years, amounts of N in 8-9 months old aboveground M. pruriens, P. phaseoloides and natural fallow biomass and litter w...

Maize/cassava were intercropped between hedgerows of Senna spectabilis [(DC.) Irwin and Barneby], Flemingia macrophylla [(Willd.) Merrill] and Dactyladenia barteri [(Hook f ex Oliv.) Engl.] for five consecutive years on an Ultisol in southern Cameroon. Crop yields and hedgerow biomass production ...

Although the West-African moist savanna zone has a high potential for crop production, yields on farmers' fields are, on average, far below this potential, mainly due to the low use of external sources of nutrients. Since the mid-1990s, it has become clear that in order to upgrade crop production...

Earthworm populations (predominantly Hyperiodrilus africanus and Eudrilus eugeniae) were sampled monthly for 1 yr during 1994 and 1995 in natural regrowth vegetation fallow (dominated by the natural fallow shrub Chromolaena odorata L.), planted fallow (the woody species Senna siamea Lam., Leucaen...
