Abstract
Declining soil fertility is a critical agricultural challenge facing smallholders in
central Kenya. A study to improve soil fertility and farm productivity in the area was
carried out during the period 2003 to 2007. Problem- solving tools were used to build the
broad conceptual and methodological approaches needed to address farming constraints.
The study identified farming systems constraints and disseminated “best-bet” integrated
soil fertility management (ISFM) interventions using participatory methods and mutual
collaborative action. This paper describes processes in the participatory approaches,
project milestones and joint experiences that were gained. The participatory approaches
included Participatory Rural Appraisal (PRA), Mother-baby approach (M-B approach),
Farmer training groups (FTGs), Annual stakeholder planning meetings, Village training
workshops, Cross-site visits and Participatory Monitoring and Evaluation (PM & E).
Food shortage was the main problem identified by farmers resulting from low crop
yields. The causes of poor yields were biophysical factors, but several socio-economic
factors influenced farmer ability to manipulate farm productivity. Village training
workshops attracted a 20% higher farmer turnout than mother trial field days. Farmer and
experimental evaluations showed that the most favoured technologies were tithonia,
manure, manure-fertilizer combinations, and tree legumes while the most effective
dissemination pathways included demonstrations, farmer training grounds, field days and
farmers’ groups. Using PM& E procedures, farmers developed indicators that they used
to monitor progress, and annual ISFM milestones were achieved, leading to the
achievement of overall project objectives. Innovative adjustments to ISFM technology
dissemination were proposed by both farmers and scientists.
