Abstract:

Infiltration rate, bulk density, saturated hydraulic conductivity, organic carbon content, particle size distribution and water content, for bush cover, grass cover and bare ground sites within four representative soil types of the overgrazed Mukogodo rangelands were assessed. All properties, except particle size distribution, differed significantly among soil cover types consistently, but rarely among soil types. Surface soil properties differed more often than those of the sub-surface layers. The infiltration rates of grass and bush cover sites were three to four times higher than bare ground. Consistently, bare-ground surface soils retained significantly less water than vegetated sites and also held the least amount of plant-available water. The results indicate that depletion of soil cover due to overgrazing has adversely affected the soil physical properties important for soil water intake, storage and availability to plants
