The Potential of Organic and Inorganic Nutrient Sources in Sub-Saharan African Crop Farming Systems
(2012-02)
he Potential of Organic and Inorganic Nutrient Sources in Sub-Saharan African Crop Farming System
Nitrogen fertilizer equivalencies of organics of differing quality and optimum combination with inorganic nitrogen source in Central Kenya
(Kluwer Academic Publishers, 2004)
Decline in crop yields is a major problem facing smallholder farmers in Kenya and the entire Sub-Saharan region. This is attributed mainly to the mining of major nutrients due to continuous cropping without addition of ...
Nitrogen recovery by alley-cropped maize and trees from 15N-labeled tree biomass in the subhumid highlands of Kenya
(Springer-Verlag, 2000-05)
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, ...
Evaluation of Leucaena leucocephala as a source of N for maize
(1997-01)
Prunings of leucaena [Leucaena leucocephala (Lam.) De Wit]
have long been regarded as a useful alternative to N fertilizer,
but N use efficiency by crops is often low. The potential exists
to synchronise nutrient ...
The diversity of rural livelihoods and their influence on soil fertility in agricultural systems of East Africa – A typology of smallholder farms
(2010)
Technological interventions to address the problem of poor productivity of smallholder
agricultural systems must be designed to target socially diverse and spatially heterogeneous farms and farming systems. This paper ...
Available technologies to replenish soil fertility in East Africa
(Springer, 2006)
Low inherent soil fertility in the highly weathered and leached soils largely accounts for low and unsustained crop yields in most African countries. But in particular, the major nutrients, nitrogen (N) and phosphorus (P), ...
Effect of incorporating Cassia siamea prunings on maize yield in an alley cropping trial in semiarid Kenya
(1997)
The influence of soil-incorporated Cassia siamea prunings on nutrient status of maize leaves, grain and yield was studied in an alley cropping experiment in semiarid Machakos, Kenya, during the 1988 long and short rainy ...
Arbuscular Mycorrhizal Fungi Colonization in the Rhizosphere of Aspilia pruliseta Schweif. ext Schweif in the Semiarid Eastern Kenya
(Sage, 2020-09)
The use of arbuscular mycorrhizal fungi (AMF) to enhance soil phosphate uptake is a biological technique considered to cure
phosphate deficiency in soils. This study investigated association of Aspilia pruliseta Schweif ...
Soil Greenhouse Gas Fluxes From Maize Production Under Different Soil Fertility Management Practices in East Africa
(2020-06)
In sub-Saharan Africa (SSA), few studies have quantified greenhouse gas (GHG) emissions following application of soil amendments, for development of accurate national GHG inventories. Therefore, this study quantified soil ...
Farming systems’ typologies analysis to inform agricultural greenhouse gas emissions potential from smallholder rain-fed farms in Kenya
(Elsevier B.V, 2020)
Most sub-Saharan Africa smallholder farming systems are highly heterogeneous. Direct quantification of greenhouse gas emissions from these farming systems is hampered by di- versity at farm-level. Each farm contributes ...
