A litter bag technique was used to study the decomposition and release of N, P, K, Ca and Mg from Leucaena leucocephala and L. pallida prunings and cattle manure in a hedgerow intercropping trial conducted in the Ethiopian highlands. Hedgerow inter-cropping (also called alley cropping or alley fa...

The N.P.K. Ca and Mg release patterns of the leaves of four accessions of Sesbania species and two accessions of Leucaena species were evaluated in a 5-week laboratory incubation. Leaves of these leguminous trees, applied at an equivalent rate of 3 t dm ha-1, were significant sources of N, K and ...

Poor drainage of Vertisols and nitrogen (N) and phosphorus (P) deficiencies are some if the major constraints to food and feed production in the Ethiopian highlands. The effects of soil drainage and P supply on N fixation by annual trifolium species and their residual value to succeeding crops wa...

Balances between nutrients applied or mineralized and nutrients removed in maize grain and stover were calculated in a hedgerow intercropping experiment in which Leucaena leucocephala and L. pallida prunings and cattle manure were applied. Hedgerow intercropping (also called alley cropping) is an...
