Abstract |
Restoration of renosterveld invaded by alien grasses may be aided by the artificial reduction of soil N and P levels. This premise was tested by applying systemic and contact herbicides to reduce alien grass biomass and sugar and gypsum to reduce soil N and P contents. Sugar additions negatively affected the growth and photosynthesis of invasive grasses and also that of resident and introduced native species known to be adapted to nutrient impoverished soils. Also, no affect of sugar additions on soil total N content was observed, a possible consequence of bacterial immobilization of N in a form unavailable to plants.
