dc.description.abstract | A study was conducted to establish the conhibution of reseeding using
indigenous perennial grass (Bush rye) and Cenchrus ciliaris (African foxtail
grass) in improving soil hydrological properties and thus controlling soil erosion
in the degraded areas of Kibwezi district, Kenya. The experiment was carried out
using simulated rainfall, Kamphorst simulator, on bare ground and at different grass
stubble heights. The experimental plots were set up under sprinkler irrigation
controlled conditions to ensure availability of sufficient moisture for seed
germination and subsequent establishment. Results showed that sediment
production as a function of runoff and infiltration capacity was significantly
different (p<0.05) at different grass stubble heights. Cenchrus ciliaris had the
greatest influence on improving soil hydrological properties. Enteropogon
macrostachyus and Eragrostis superba were ranked second and third, respectively.
This was attributed to the growth characteristics of the perennial grasses. Generally,
an increase in grass height increased infiltration capacity, reduced runoff and
sediment production. | en |
