Description Fallowing and conservation agriculture are sustainable farming practices that can be used for soil and water conservation.
The objectives of the study were to evaluate the effects of different conservation agriculture practices on rainfall infiltration
and soil and water losses across 4 sites, using simulated rainfall. The study was carried out at Domboshawa and the Institute
of Agricultural Engineering and Chikwaka smallholder farming areas, 4 sites with different soil types. Conservation agriculture practices evaluated were mulch reaping (MR) and clean reaping (CR) at Domboshawa with 5% clay and the Institute
of Agricultural Engineering (IAE) with 50% clay. The study also evaluated runoff losses from fallow plots subjected to no
tillage (NT) and conventional tillage (CT) at ICRAF Domboshawa site (20% clay) and fallows subjected to CT in Chikwaka
smallholder farming areas (4% clay). Infiltration rates were greater under conservation agriculture practices (>35 mm∙h
-1
)
when compared to CT (
