Abstract:
A study was conducted to establish the contribution of Eragrostis
superba, Enteropogon macrostachyus and Cenchrus ciliaris in
improving soil hydrological properties in semi-arid Kenya.
Kamphorst rainfall simulator was used on bare ground and at
different grass stubble heights. The experiment was set up under
sprinkler irrigation system. Sediment production as a function of
runoff and infiltration capacity was significantly different (p<0.05)
at different stubble heights. Cenchrus ciliaris had the greatest
influence on improving soil hydrological properties followed by
Enteropogon macrostachyus and Eragrostis superba respectively.
An increase in grass height increased infiltration capacity, reduced
runoff and sediment production.
