  1. 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...
  2. The Relationship between Soil Water Status, Rainfall and the Growth of <em>Eucalyptus grandis</em>

    Item type: Journal Article • Journal: South African Forestry Journal
    Available soil water is recognised as the main factor influencing the growth of commercial plantations in southern Africa. This is of strategic importance as successive rotations of demanding species such as Eucalyptus grandis may be depleting the soil water reserves...
  3. Veldtoestand en neiging in Kalahari‐duineveld onder ‘n ekstensiewe veeboerderystelsel

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Plantopnames is gedurende 1970 tot 1985 in die Kalahari‐duineveld (Acocks, 1975; Veldtipe no. 16a4) op die proefboerdery‐eenheid Massakloutjie in Noordwes‐Kaapland onderneem. Reënval het gedurende die proefperiode gewissel tussen 111 mm (1982–83) en 593 mm (1973–74). Die totale basale plantebedekking het...
  4. The influence of an <em>Acacia karroo</em> tree on grass production in its vicinity

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The investigation was concerned with the impact of an Acacia karroo tree on the productivity of the surrounding herbaceous layer.
  5. Die produksie van smutsvingergras in die wes‐transvaal<sup>1</sup>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Die produksie van Smutsvingergras (Digitaria eriantha) is in yerskeie proewe in die Hoëveldstreek, op Potchefstroom, in die verlede bepaal. Hierdie proewe is oor ‘n lang periode op verskillende grondsoorte en met verskillende bemestingspeile uitge‐voer. Alle resultate is saamgevoeg en met...
  6. Determinants of herbaceous plant species composition on a number of ranches in the north‐western Transvaal

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Herbaceous plant species composition was measured on ranches in the Thabazimbi district, Transvaal, to obtain veld composition scores and to quantify the relations between such scores and certain determinants considered important in influencing species composition. Determinants investigated were mean annual...
  7. A model for the evaluation of different production strategies for animal production from rangeland in developing areas: An overview

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    An interactive user‐friendly computer package is being developed to assist planners and managers with the evaluation of different livestock production strategies in semi‐arid regions. It comprises a hierarchy of simulation models that predict over time the effects of past and...
  8. Importance of rainfall oscillations in agricultural planning

    Importance of rainfall oscillations in agricultural planning

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Evidence seems to indicate that the rainfall in the summer rainfall area of the RSA exhibits an oscillatory nature with a period of 16–20 years. To help maize farmers in planning for a dry or wet cycle the most recent...
  9. The effect of simulated rain on the efficiency of herbicides in the presence of maize stubble

    The effect of simulated rain on the efficiency of herbicides in the presence of maize stubble

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The effect of the amount of simulated rain and stubble on the efficiency of herbicides was examined in a glasshouse study. Four different amounts of maize stubble (0–3 500 kg ha-1) and nine different amounts of simulated rain (0–20 mm)...
  10. Effect of soil surface amendments on runoff and erosion from simulated rain applied to a sesquioxidic soil

    Effect of soil surface amendments on runoff and erosion from simulated rain applied to a sesquioxidic soil

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Simulated rainfall, using low conductivity water, was applied at an intensity of 63 mm h−1 to a field soil of the Doveton series (a kaolinitic, sesquioxidic clay soil at Cedara in Natal, recently cultivated out of pasture) after pre-treatment of...
