MULI, MRMUTISYAJOSEPH.  1991.  Ndutu,J.M. (1991). Phosphorus adsorption properties of some acid soils of Kenya. Discovery and innovation Journal. 17: 60-66. Asian Journal of Agriculture and Rural Development. : Asian Economic and Social Society Abstract
The influence of soil type, vegetation and landuse on infiltration rate into soils of the semi-arid Sirima and Mukogodo catchments in Likipia District, Kenya was investigated during the dry and the wet seasons by double cylinder infiltrometer. Infiltration rates significantly differed between soils and sites in both areas, and were highest under tree/bush, intermediate on open grass and lowest on bare ground. Cultivation temporarily increased infiltration above that of tree/bush sites. Bulk density, saturated hydraulic conductivity and organic carbon significantly influenced infiltration in both areas, but soil cracking and swelling in Sirima during the dry and the wet season respectively, partially obscured the influence of the physical parameters on infiltration rate
