Nitrogen recovery by alley-cropped maize and trees from 15N-labeled tree biomass in the subhumid highlands of Kenya
The effectiveness of tree-leaf biomass as a source of N to crops in agroforestry systems depends on the rate at which crops can obtain N from the biomass. A study was conducted to determine the fate of 15N labeled, ...
Soil Invertebrate Macrofauna Composition within Agroforestry and Forested Ecosystems and their Role in Litter Decomposition in Embu, Kenya
Adequate food to meet the needs of an ever-increasing population is a major challenge for most developing countries, especially in the tropics. Despite this, few new technical packages capable of increasing net returns ...
The role of agroforestry trees in intercepting leached nitrogen in the agricultural systems of the central highlands of Kenya.
(East African Agricultural and Forestry Journal, 2003)
Application of N-rich tree biomass to crop fields in agroforestry associations can cause a build-up of mineral-N in the top soil in excess of crop demand during early stages of crop growth. It is therefore important ...
