Soil erosion control in Kenyan coffee: a review
Soil erosion is a serious problem associated with tropical agriculture. It is responsible for the degradation of soil physical characteristics such as infiltration rate, soil structure and crusting resulting in reduced soil productivity. Erosion also decreases fertilizer use efficiency by increasing nutrient losses due to runoff. The goal of erosion control is to increase infiltration rate and reduce runoff on the soil surface. Erosion control measures are divided into three categories namely agronomic, mechanical and soil management methods. Agronomic measures rely on the protective cover provided by vegetation. They include intercropping, cover cropping, strip cropping, mulching and high-density plantings, etc. Mechanical measures involve some modification to the land surface, and include terracing, contour bunds and contour planting. Soil management measures involve the maintenance and improvement of soil fertility through proper land use and fertilization.
