Abstract Three aspects of soil nutrient ecology in an Acacia sieberana savanna were studied. First, information was collected about the effects of the savanna tree species Acacia sieberana on soil fertility, in terms of isolated tree effects and in terms of tree density effects. Second, the...
Abstract Reproductive and aerial tillering dynamics in Lolium perenne L. (perennial ryegrass) was monitored for two years under grazing. Reproductive tillers were observed from winter (June) to midsummer (February) with the main period of initiation occurring in spring to early summer (August to...
Abstract Dietary preference of bushbuck (Tragelaphus scriptus) and boer goats (Capra hircus) was determined for sixteen Subtropical Thicket plant species using cafeteria style selection trials. Principal components analysis was used to identify major axes of variation in the chemical contents of...
Abstract The effect of maturity stage on the total yield (all harvests throughout the season) of some forage components and on the chemical composition and in vitro dry matter digestibility (IVDMD) (first harvest) of babala, was investigated. The effects of various preservation methods on the...
Abstract Determination of carrying capacity for mixed‐ or multi‐species grazing systems is complex. Commonly, each species is compared to the standard large stock unit (LSU) used in conventional agriculture. However, this approach does not allow for ecological separation, and thus overlooks the...
Abstract Degradation of natural rangeland is a serious problem throughout southern Africa. It has been suggested that incorrect grazing management practices have resulted in a decrease in the production potential of rangelands. In order to explore the nature and extent of degradation at the...
