Abstract
Increased cultivation intensity in response to rising rural population pressure and cash cropping opportunities places considerable demands upon soil fertility in smallholder farming systems of the Central Kenya Highlands. Poor households typically practise mixed farming (dairy with maize, coffee/tea) on holdings of less than 1 ha. Owing to cost they use little inorganic fertilizer (Harris et al., 1998) in support of continuous cultivation. They are more likely to rely upon organic inputs, particularly manure (a mixture of ruminant livestock excreta and plant material, often rejected forage and bedding), to help maintain beneficial soil structural properties and nutrient levels (Woomer & Muchena, 1996).
