A rotating?boom rainfall simulator is being used to measure soil losses and run?off from natural veld in different successional stages and different slopes.
Run?off as much as 94,34% of the applied volume of water and soil loss of 5,74 t|ha were recorded from a pioneer grass cover with a 2,42% slope. Of all the variables under consideration, basal cover had the greatest influence on run?off, while slope had statistically no significant influence. Both basal cover and slope had statistically a significant (P < 0,05) effect on the amount of soil loss from natural veld.
Basal cover was highly significantly related to soil loss (r2 = 0,69), but slope had no significant relationship to soil loss and run?off.
