Results and discussion
Table 3 presents runoff, soil loss and dry matter yield results for all four treatments over
the three years 1989-1991. All results are the mean of three replicate plots.
As expected, runoff and soil loss was highest from the bare plot. Runoff during the
growing season from treatment plots varied from 9 to 20% of rainfall during the same
period, being highest for up and downslope cultivation (treatment 1). Total soil loss was
