Introduction: In arid regions, soil losses are caused by torrential rainfall events and by the erosive
energy of runoff.
Objectives: To quantify the impact of the use of different types of vegetation cover on soil erosion
and soil deposition caused by overland flow.
Methodology: The experiment was carried out from July to September 2017 under a randomized
block experimental design with three replications. The treatments evaluated were maize harvest
residues and buffel grass (Cenchrus ciliaris L.) sowing (MHR + G), maize harvest residues (MHR), buffel
grass sowing (G), and the control (C).
Results: The MHR + G treatment reduced erosion by 44 % (26.3 t·ha-1) compared to the control
(58.6 t·ha-1). Soil deposition was 47.6 and 51.7 t·ha-1 with MHR + G and G, respectively, while in C
was 26.1 t·ha-1
Limitations of the study: The results found are valid for the soil and water conditions of this study
Originality: There are few technical and scientific reports on the behavior of soil particle removal
and deposition processes under runoff conditions.
Conclusions: The layer thickness of soil removed and deposited, under overland flow conditions,
depends on the type of soil cover. The MHR + G treatment significantly reduced soil erosion, making
it a viable alternative.
