Partial balance of nitrogen in a maize cropping system in humic nitisol of Central Kenya

Kimetu, J. M.; Mugendi, D.N.; Bationo, A.; Palm, C. A.; Mutuo, P. K.; Kihara, J.; Nandwa, S.; Giller, K. (Kluwer Academic Publishers, 2006-11)

The application of nitrogen in a soil under agricultural production is subject to several pathways including de-nitrification, leaching and recovery by an annual crop. This is as well greatly influenced by the management ...

Adoption potential of selected organic resources for improving soil fertility in the central highlands of Kenya

Mugwe, J.; Mucheru-Muna, M.; Mugendi, D.; Kung’u, J.B.; Bationo, A.; Mairura, F. (Springer Science+Business Media B.V., 2009)

Soil fertility decline is the major cause of declining crop yields in the central highlands of Kenya and elsewhere within the African continent. This paper reports a study conducted to assess adoption potential of two ...

Soil organic carbon dynamics, functions and management in West African agro-ecosystems

Vanlauwe, B.; Waswa, B.; Kimetu, J.; Kihara, J.; Bationo, A. (2007-04)

Soil fertility depletion has been described as the single most important constraint to food security in West Africa. Over half of the African population is rural and directly dependent on locally grown crops. Further, 28% ...

Enhancement of food productivity using leguminous shrubs in the Eastern highlands of Kenya

Mugendi, D.N.; Mucheru-Muna, M.; Mugwe, J. N.; Bationo, A. (Elsevier, 2003)

Declining soil productivity is a major challenge facing smallholder farmers in eastern highlands of Kenya. This decline is caused by continuous cultivation of soils without adequate addition of external inputs in form of ...

Conservation tillage, local organic resources and nitrogen fertilizer combinations affect maize productivity, soil structure and nutrient balances in semi-arid Kenya

Mugendi, D.N.; Kihara, J.; Bationo, A.; Martius, C.; Vlek, P. L. G. (Springer Netherlands, 2011-06)

Smallholder land productivity in drylands can be increased by optimizing locally available resources, through nutrient enhancement and water conservation. In this study, we investigated the effect of tillage system, organic ...

Technologies for sustainable management of sandy Sahelian soils

Vanlauwe, B.; Kihara, J.; Waswa, B.; Bationo, A.; Ouattara, B. (2014-07-15)

Soil fertility is the most limiting factor for crop production in the Sahelian zone of West Africa. Over 95% of soils in this region are sandy and pose a great challenge to sustainable management. The poor structure and ...

Nitrogen fertilizer equivalencies of organics of differing quality and optimum combination with inorganic nitrogen source in Central Kenya

Mugendi, D.N.; Kimetu, J.M.; Palm, C.A.; Mutuo, P.K.; Gachengo, C.N.; Bationo, A.; Nandwa, S.; Kung'u, J.B. (Kluwer Academic Publishers, 2004-02)

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 ...
