in southern Mali. Contour ridge tillage (CRT), a water conservation
technique had been locally applied since 1990. The objective of this study was
to determine the effects of CRT compared with farmer conventional agriculture
practice (NoCRT) on runoff, soil loss, nutrient loss, moisture conservation
and cereals yields under rainfed conditions in two Southern Mali sites, in
2016 and 2017 in farmer fields. Measurements were performed on erosion
plots composed of CRT and NoCRT plots from which water samples were
collected to determine sedimentation levels, concentration and nutrients
losses using pairwise comparison. Average runoff coefficient in NoCRT plots
was 35.62% compared to 19.25% for the CRT plots explaining a runoff reduction
of 46%. Mean soil losses of 12,095 t·ha−1 and 4970 t·ha−1 were respectively
measured in NoCRT and CRT plots. Losses in calcium, magnesium and potassium
nutrients in the NoCRT plots were 80%, 66%, 75% higher compared
to CRT ones, respectively. Sorghum grain yield was at least two folds higher
in CRT plots compared to the NoCRT plots. Maize average grain yield was
87% higher in CRT plots than in the NoCRT. For sustained soil productivity,
CRT is advocated as a better soil and water management technique than the
NoCRT one.","2019-10","published",,"Journal of Environmental Protection (TSI)","10","10","Scientific Research Publishing",,"1333-1360",,,,,,"doi:10.4236/jep.2019.1010079",,,,,"TRUE",,"2152-2197",,,,,,"","https://doi.org/10.4236/jep.2019.1010079","https://scholar.google.com/scholar?q=Soil+Erosion+Control+and+Moisture+Conservation+Using+Contour+Ridge+Tillage+in+Bougouni+and+Koutiala,+Southern+Mali&hl=en&as_sdt=0,5","pub",,"Africa RISING Project","",,,,,,"",,,,,,,"",,,,,"",,,,,"","",,,,,"","",,,,,
