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, ...
Mineral-N movement in an agroforestry system in the central highlands of Kenya
Application of N-rich tree biomass to crop fields in agroforestry associations can cause build-up ofmineral-N in the top soil in excess of crop demand during early stages of crop growth. It is therefore impcrtant to moniter ...
Consequences of Organic-Mineral N Soil Fertility Amendments on Nitrogen Uptake and Maize Grain Yield in the Smallholder Farms of Meru South District, Kenya
(Sky Journals, 2012-11)
The central highlands of Kenya is generally densely populated and declining land productivity with reduced crop yields has been a major problem facing the smallholder farmers in the region. Land sizes are small and this ...
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 ...
Improving food production using ‘best bet’ soil fertility technologies in the Central highlands of Kenya
(Springer Netherlands, 2007)
Declining crop productivity is a major challenge facing smallholder farmers in central highlands of Kenya. This decline is caused by continuous cultivation of soils without adequate addition of external inputs in form of ...
