Agriculture resource management in smallholder systems in the central kenyan highlands. Technical Report and Financial Statement.

Kapkiyai, Jane J.; Karanja, N.; Woomer, P.; Bunyasi, S.; Murage, E. W. (1997)
Effect of selected grain legume residues on soil phosphorus dynamics in Western Kenya

Kapkiyai, Jane J.; Duxbury, John (2007-11)

The low availability of phosphorus (P) in many tropical agricultural lands is a major constraint to crop production. Management of legumes that can grow well on low P soils while fixing optimal amounts of N may be a useful ...
Household level influence on spatial variability of soil properties in Western Kenya

Kapkiyai, Jane J.; Degloria, Stephen D.; Duxbury, John M.; Pell, Alice N.; Vanlauwe, Bernard; Mbugua, David M. (2006-07)

Spatial variability in soils occurs naturally from pedogenic factors, but it can also occur as a result of land use and management. Often the net effect of different soil management options and combinations and social ...
Legume crop-based soil phosphorus management and effects on maize (Zea mays) productivity in western Kenya

Kapkiyai, Jane J. (2008)

The low availability of phosphorus (P) in the oxisols of western Kenya is a major constraint to crop production. Some legume genotypes posses stress response mechanisms that enhance their ability to access P in low P soils ...
Performance, soil phosphorus mobilization and rhizospheric effects of some grain legumes grown in oxisols of Western Kenya

Kapkiyai, Jane J.; Duxbury, John M. (2006-07)

Phosphorus (P) availability to crops may be affected by agronomic measures either through the modification of soil properties or through crop impact on soil P dynamics. Most legumes display one or more of the various ...
Soil organic matter and nutrient dynamics in a Kenyan nitisol under long-term fertilizer and organic input management

Kapkiyai, Jane J.; Karanja, Nancy K.; Qureshi, Javaid N.; Smithson, Paul C.; Woomer, Paul L. (1999-11)

Three soil fertility management practices relevant to smallhold farming systems in the East African Highlands were tested in an 18 yr-old experiment on a humic nitisol (Kikuyu Red Clay) under a maize-bean rotation. These ...
