The role of plant residues in soil productivity: farmers'knowledge and practices in Embu District, Kenya
(Soil Science Society of East Africa, Nairobi (Kenya), 2003)
Plant residues from trees, crops or weeds play an important role in determining the soil fertility status in smallholder farmers of the central highlands of Kenya region. A study was conducted in Embu district of Kenya, ...
Land and water management in Kenya: towards sustainable land use.
(2000)
Preliminary findings on the effects of land use in the Masinga Dam catchment, Kenya, on the storage capacity of the reservoir are presented. Remote sensing and GIS techniques, supplemented with ground reports, were used ...
Nutrient losses in eroded soil material from some Kenyan soils
(1989)
Nutrient loss is one of the factors which causes productivity decline in soils when erosion occurs. This paper gives preliminary results on nutrient losses in eroded soil material in relation to original soil material of ...
Participatory Evaluation of Residue Management Effects of Green Manure Legumes on Maize Yield in the Central Kenya Highlands
(2005)
An on-farm study to evaluate three methods of applying legume residues in maize-based cropping systems in the central Kenya highlands was initiated in 1997 and conducted for three years. The legumes involved in the study ...

(2000)
This report reviews work on legume cover crops in eastern Africa and provides a summary of recommendations of the appropriate germplasm, management and posible niches for these plants in farming systems. It briefly identifies ...
Crop response to soil water content under fertilized and non-fertilized conditions
(2000)
Observations on crop response to soil water content were made over a 2-year period from 1991 to 1992 on 3m by 10m plots at Kabete, Kel1ya. The total anmial rainfall was 948 and 1125mm in 1991 aind 1992 respectively with ...

(2011)
A two phase study was carried out from 2002 to 2005 in the semi-arid rangelands of Kajiado District, Kenya to determine the effect of introduced forage legumes on soil fertility improvement of natural pastures. During ...
Soil erosion effects on productivity of a humic nitisol
(2000)
This study was carried out with the aim of assessing the effect of accelerated erosion on soil productivity of a humic nitisol at Kabete, Kenya. Twenty runoff plots which had been subjected to varying levels of ero¬sion ...
