    Study on the early effects of several weed-control methods on Parthenium hysterophorus L.

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    We carried out a trial in the Hluhluwe-iMfolozi Park comparing three herbicides and two manual control techniques for controlling the annual weed Parthenium hysterophorus L. The herbicides 2,4-D amine (480 g ai l−1), metsulfuron methyl (600 g kg−1) and picloram...
  3. Rangeland degradation in semi-arid Swaziland: effects of dip-tanks on herbaceous vegetation and soil properties

    Rangeland degradation in semi-arid Swaziland: effects of dip-tanks on herbaceous vegetation and soil properties

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    This study investigated dip-tank use effects on herbaceous vegetation and soil, and relationships between environmental and species variables. Eight dip-tanks, three each in sandy (DPBS) and loamy (DYRL) soils, and two in stony (ROSG) soils were used. Data were collected...
  4. What are the long-term effects of high-density, short-duration stocking on the soils and vegetation of mesic grassland in South Africa?

    What are the long-term effects of high-density, short-duration stocking on the soils and vegetation of mesic grassland in South Africa?

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    High-density, short-duration stocking (HDG) is gaining popularity amongst farmers in the South African mesic grasslands, but little is known about its potential impact on natural resources. Using a fence-line contrast approach, this study compared the long-term effects of HDG with...
