Effects of biological techniques in soil conservation and subsoil inorganic-N accumulation in the central highlands of Kenya
Soil erosion and nutrient leaching are some of the factors hindering realization of full crop production potential in the central highlands of Kenya. A participatory trial involving use of calliandra, leucaena, napier, ...
Tree biomass decomposition, nitrogen dynamics, and maize growth under agroforestry conditions in the subhumid highlands of Kenya
Declining crop yields, consequent to continuous cropping without external addition of adequate nutrients, is a major problem facing smallholder farmers in the tropics. The high cost of inorganic fertilizers has led to ...
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 ...
