- Exploring new pathways for innovative soil fertility management in KenyaOnduru, D.; de Jager, A.; Gachini, G.; Diop, J. (International Institute for Environment and Development, 2001)This working paper discusses the impact of a multi-institutional research programme in low potential areas of Kenya. The programme elaborated nutrient balances, combined with economic analysis, to better understand causes and effects of soil fertility decline. Alongside, better soil fertility management practices were developed using a participatory technology approach. This paper assesses to what extent farmers changed their practices, if the program has influenced way of working with extension and research, or has led to better informed policies.
- Soil fertility regeneration in KenyaNandwa, S.; Onduru, D.; Gachimbi, L. (London: International Institute for Environment and Development, 2000)Agriculture plays a major role in the Kenyan economy, ensuring that the country is self-sufficient in food, generating income, earning foreign exchange and providing raw materials for the industrial sector. However, soil fertility is declining across the country, affecting many regions with varying biophysical and agronomic characteristics. This chapter describes the developments in soil fertility management in three regions of medium and high agricultural potential. Its focus is on the adoption of new soil fertility management techniques, in particular the use of compost and double dug beds, and their contribution to sustainable farming.
