Table 4 Monthly and annual soil loss (SL) of treatments and the relative effect (RE) of graded soil bund treated as compared to the non-treated plots

From: Runoff and soil loss responses of cultivated land managed with graded soil bunds of different ages in the Upper Blue Nile basin, Ethiopia

Treatment Monthly Annual (four months)
Month SL (t ha−1) REc (%) SL (t ha−1) REc (%)
New soil bund (Pnew) Jun 5.75 − 63.69a (− 52.6b) 23.50 − 59.59a (− 48.3b)
July 11.53 − 54.51a (− 44.2b)
Aug. 5.74 − 61.27a (− 49.3b)
Sep. 0.48 − 77.75a (− 67.1b)
Old soil bund (Pold) Jun 12.13 − 23.44 45.56 − 21.66
July 20.66 − 18.47
Aug. 11.31 − 23.65
Sep. 1.45 − 32.38
Non-treated (Pnon) Jun 15.85 - 58.15 -
July 25.34 -
Aug. 14.81 -
Sep. 2.14 -
  1. SL is monthly and annual soil loss (in t ha−1), RE is the relative effect of treatments on runoff (in percent), and “a” and “b” are the relative effects of Pnew compared to Pnon and Pold, respectively
  2. cThe relative effect is calculated by considering the runoff from non-treated plot 100%
