AD, AH are more effective in reducing runoff and erosion, and increasing rainfall infiltration amount than CP. Tillage practices are more effective in decreasing erosion than runoff as the SRB (89%) higher than RRB (80%). The SRB and RRB of tillage practices are decrease with the increase of slope gradient. CP is effective in minimizing runoff and erosion, with an exception on steeper slope, which can accelerate erosion.
