  1. Effect of seeding date on the performance of grasses and broadleaf species evaluated for cover crop management in two wine grape regions of South Africa

    Effect of seeding date on the performance of grasses and broadleaf species evaluated for cover crop management in two wine grape regions of South Africa

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    A selection of species suitable for cover crop management in the different wine grape regions is required to enable more producers to apply this environment friendly practice in a sustainable manner as part of an integrated production strategy. The effect...
  2. Effects of soil surface management practices on soil and tree parameters in a ‘Cripps Pink’/M7 apple orchard 1. Mineral nutrition

    Effects of soil surface management practices on soil and tree parameters in a ‘Cripps Pink’/M7 apple orchard 1. Mineral nutrition

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Effects on soil, leaf and fruit element concentrations of organic (compost, straw mulch and hand weeding) and integrated (inorganic fertilisers and herbicide usage; IP) soil surface management practices in the tree rows, in combination with weed covers, cover crops and...
  3. Effects of soil surface management practices on soil and tree parameters in a ‘Cripps Pink’/M7 apple orchard 2. Tree performance and root distribution

    Effects of soil surface management practices on soil and tree parameters in a ‘Cripps Pink’/M7 apple orchard 2. Tree performance and root distribution

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Effects of integrated production (IP) and organic-acceptable soil surface management practices were investigated in a ‘Cripps Pink’/M7 apple orchard in the Elgin area, South Africa. Work row treatments included cover crops, weeds and straw mulch. In the IP tree rows,...
  4. Effects of oats and grazing vetch cover crops and fertilisation on microbial biomass and activity after five years of rotation with maize

    Effects of oats and grazing vetch cover crops and fertilisation on microbial biomass and activity after five years of rotation with maize

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Degraded soil quality could be improved by cover crops. This study determined effects of maize–oats and maize– vetch rotations with or without fertilisation on soil microbial biomass and activity. Winter treatments were oats, vetch and weedy fallow, in rotation with...
  5. Grond‐ en afloopverlies bepalings vanaf natuurlike veld, met behulp van ‘n reënvalnabootser

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    ‘n Oorhoofse roterende reënvalnabootser is gebruik om die sediment‐ en afloopverliese vanaf natuurlike veld in verskillende suksessiestadia en teen verskillende hellings te bepaal.
  6. Afloopstudies vanaf natuurlike veld in verskillende suksessiestadia van die sentrale oranje‐vrystaat

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Afloopbane met ‘n helling van 4,13% is gebruik om die afloopverliese, fitomassaproduksie en waterverbruiksdoel‐treffendheid (WVD: Bogrondse fitomassa geproduseer in verhouding tot die evapotranspirasieverliese), van natuurlike veld in verskillende suksessiestadia vir die periode Julie 1977 tot Junie 1983 te monitor.
  7. 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...
  8. Veld condition in the south‐eastern Transvaal and its effect on grazing capacity

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    A survey conducted on sites throughout the south‐eastern Transvaal, representing 1,4 million hectares of natural veld has confirmed the parlous state of composition, cover and vigour. The implications which these conditions hold, not only for conservation of soil and water...
  9. Effect of slope and plant cover on run‐off, soil loss and water use efficiency of natural veld

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Run‐off and soil loss were monitored from a climax, subclimax and pioneer veld, each on a 5,9%, 4,1% and 2,1% slope, by means of a rainfall simulator on a Valsrivier soil form. With rainfall intensity, soil moisture content at the...
  10. 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...
