The following data were used for a watershed experiencing soil erosion problem:
Rainfall Erosivity Index = 280 MJ mm ha-1 h-1 year-1, Soil Erodibility Index = 0.38 ton ha h MJ-1 mm-1, Slope length = 200 m, Average slope of the land = 8%, Slope steepness factor = 0.85, Cropping management factor = 0.35, and Conservation practice factor = 0.60
If the slope length is reduced to half, percentage reduction in soil loss (round off to 2 decimal places) is _______.
