Assessment of erosion damage in Ndome and Ghazi, Taita Taveta, Kenya: Towards an integrated erosion management approach
Waswa, Fuchaka; Gachene, C K K; Eggers, Helmut (Department of soil science, University of Nairobi, 2002-03)Aerial photograph interpretation on erosion trends from 1961 to 1998 showed that by 1998, approximately 17 and 50% of agricultural land in Ndome and Ghazi respectively had been permanently lost due to the combined effect ... -
Crop response to soil water content under fertilized and non-fertilized conditions
Gachene, C K K; Mbuvi, J P; Linner, J; Jarvis, N (Department of soil science, University of Nairobi, 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 ... -

Legume cover crops for soil fertility improvement in the highlands of eastern Africa region. Report of an AHI workshop
Gachene, C K K; Palm, C A; Mureithi, J G (Department of soil science, University of Nairobi, 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 ... -
Nutrient losses in eroded soil material from some Kenyan soils
Gachene, C K K (Department of soil science, University of Nairobi, 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
Mureithi, J G; Gachene, C K K; Wamuongo, J W (Department of soil science, University of Nairobi, 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 ... -
