    • Evaluation of crop cover and residue management C factors for cropping systems and management techniquesin the semi-arid region of Kenya 

      A.M, Kilewe; J.P, Mbuvi (Kenya Agricultural Research InstituteDepartment Of Land Resource Management and Agricultural Technology, University of Nairobi, 1989)
      The mean crop cover and residue management C factor for maize with conventional tillage, maize with minimum tillage, maize intercropped with beans on alternate rows, beans alone, and maize with 3 t ha -1 of maize residue ...

    • Field assessment of the effect of cumulative soil loss on soil productivity 

      C.K.K, Gachene; H, Linner; J.N, Jarvis; J.P, Mbuvi (Department of Soil Sciences, Swedish University of Agricultural SciencesDepartment of Soil Science. University of Nairobi, 2001)
      Soil erosion affects physical and chemical soil properties by reducing water infiltration rates, soil water holding capacity, soil fertility and Ieading to deterioration of soil structure. Research on the relationship ...

    • Hydraulic properties of andosols following deforestation in the northern slopes of Mt. Kenya 

      G, Kironchi; J.P, Mbuvi; FN, Gichuki (Department of Soil Science, University of Nairobi, 1999)
      Deterioration in soil hydraulic properties due to deforestation adversely affects the hydrology of catchments, especially those on mountain slopes. The effects of clearing natural forest (NF) for potato cultivation (PC) ...

    • Maize yield reduction due to erosion in a high potential area of Central Kenya highlands 

      C.K.K, Gachene; J.P, Mbuvi; N.J, Jarvis; H, Linner (Department of Soil Science, University of NairobiDepartment of Soil Sciences, Swedish University of Agricultural Sciences, 1998)
      The effect of cumulative soil loss on maize (Zea mays L.) growth and yield were investigated on a humicnitisol in Kenya during the 1993 long-rains (LR) and short-rains (SR). The runoff plots had been subjected to different ...

    • Soil Erosion Effects on Soil Properties in a Highland Area of Central Kenya 

      C. K. K, Gachene; N. J, Jarvis; H, Linner; J.P, Mbuvi (Department of Soil Science, College of Agriculture and Veterinary Medicine, University of NairobiDepartment of Soil Science, Swedish Univ. of Agricuitural Sciences,, 1997)
      One of the most important features that is neglected in many soil erosion studies in Africa is the monitoring of changes to the soil during the progress of the experiment. Objectives of this study were therefore to monitor ...

    • Soil organic carbon, nitrogen and phosphorus losses in eroded sediments from run-off plots on a clay soil in Kenya 

      C.K.K, Gachene; H, Linner; N.J, Jarvis; J.P, Mbuvi (Depanmentofsoil Science. University of NairobiDepanment of soil sciences, Swedish universiry of Agriculrural sciences, 1998)
      Poor crop growth in many parts of Kenya may be due to unfavourable soil chemical characteristics brought about by unchecked accelerated soil erosion. However information on the effects of erosion on soil fertility is ...
