  1. Toepassíng van ‘n gronderosievergelyking op natuurlike veld van die sentrale oranje‐vrystaat

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    ‘n Oorhoofse roterende rcënvalnabootscr is gebruik orn numericse waardes vir sekere faktore van die universele gronderosi‐evcrgelyking vas te stel. Alhocwei dit tydens hierdie Studie nodig was om sekere belangrike aannames te maak, het die afgeleide data betekenisvol ooreengestem met die...
  2. Die invloed van brand en maai op onbeweide langgrasveld in Natal

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The effect of burning and mowing on ungrazed tall grassveld of Natal. The trial was conducted on the Estcourt Research Station to show the effect of 14 burning and mowing treatments without grazing in the tall grassveld of Natal. The...
  3. The influence of different land‐use practices on soil erosion, herbage production and on grass species richness and diversity

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    A fence‐line contrast study compared erosion levels, herbage production and grass species diversity in Umfolozi Game Reserve (UGR) and adjacent KwaZulu (KWZ). There was no significant difference in soil loss or A‐horizon depths measured in KWZ and UGR, but there...
  4. Effect of the amount of surface maize residue on infiltration and soil loss from a clay loam soil

    Effect of the amount of surface maize residue on infiltration and soil loss from a clay loam soil

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Six levels of maize stover, expressed as percentage ground cover (0–75%) were compared under a rainfall simulator to assess the effect of surface residues on infiltration and soil loss on a clay loam soil with a 3,5% slope. Increasing the...
  5. The erodibility of some soil series In the pineapple-producing coastal area of the eastern Cape

    The erodibility of some soil series In the pineapple-producing coastal area of the eastern Cape

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    A rotating-boom rainfall simulator was used to measure soil losses from eight soil series falling within five morphologically dissimilar soil forms, i.e. Bonheim, Glenrosa, Kroonstad, Mayo and Oakleaf. The data obtained were used to calculate the soil erodibility factor (K)...
  6. Application of Empirical Soil Loss Models in southern Africa: a review

    Application of Empirical Soil Loss Models in southern Africa: a review

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Empirical soil loss models are relatively simple and have been applied in many parts of the world. The application of the Soil Loss Estimation Model for Southern Africa (SLEMSA), the Universal Soil Loss Equation (USLE) and the Revised Universal Soil...
  7. Factors affecting runoff and soil loss under simulated rainfall on a sandy Bainsvlei Amalia soil

    Factors affecting runoff and soil loss under simulated rainfall on a sandy Bainsvlei Amalia soil

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    This study was conducted on a long-term tillage experiment that was designed to evaluate appropriate tillage practices for sustainable dryland crop production. Measurements of runoff and soil loss were conducted on a sandy Bainsvlei Amalia soil (88.0% sand, 3.6% silt,...
  8. Evaluation of soil conservation measures on a highly erodible soil in the Free State province, South Africa

    Evaluation of soil conservation measures on a highly erodible soil in the Free State province, South Africa

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Soil erosion is a problem in South Africa, and is exacerbated by poor land use practices and erodible soils. Several methods are available to address the problem and a runoff trial was conducted over four rainfall seasons on an erodible,...
  9. Factors Affecting Soil Phosphate Distribution and Reactions in Cape Forest Soils

    Item type: Journal Article • Journal: South African Forestry Journal
    The amounts of various forms of phosphate in some Cape soils and the adsorption of phosphate by these soils were investigated. The levels were low and only 2% was in available form. The major fraction of phosphate in the soil...
  10. Fertilising Commercial Forest Species in Southern Africa: Research Progress and Problems (Part 1)

    Item type: Journal Article • Journal: South African Forestry Journal
    Since the inception of forest fertiliser research in Southern Africa in 1926, eight eucalypt, six pine and four acacia species have been tested, encompassing a wide range of sites in summer, winter and uniform rainfall areas. Marked deficiencies of P,...
