  1. Grass composition and rangeland condition of the major grazing areas in the mid Rift Valley, Ethiopia

    Grass composition and rangeland condition of the major grazing areas in the mid Rift Valley, Ethiopia

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    A range inventory and condition study was conducted in three altitude zones: lowland (1500-1700m), medium altitude (1700-2000m), and highland (2000-2500m). Each altitude zone was stratified into four or five important grazing areas. One area represented lightly grazed government ranches or...
  2. Longer rest periods for intensive rotational grazing limit diet quality of sheep without enhancing environmental benefits

    Longer rest periods for intensive rotational grazing limit diet quality of sheep without enhancing environmental benefits

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Intensive rotational grazing systems (also called cell grazing, holistic grazing or time-controlled grazing) are often implemented to improve production and environmental outcomes. Over recent years there has been considerable interpretation and adaption of the holistic principles that guide the management...
  3. Analysis of Stable Isotopes of Xylem Water from Plantation Trees in E. Transvaal and Zululand Indicate they Utilised Ground water During Drought of 1992

    Item type: Journal Article • Journal: South African Forestry Journal
    We investigated the stable isotopic signature of xylem sap of mature plantation trees and the associated ground water at sites in Zululand and E. Transvaal. The survey took place mainly during the drought of 1992. Results indicated a range of...
  4. Influence of stocking rate and grazing systems on available grazing in the northern cape<sup>1</sup>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The influence of rotational and continuous grazing systems, each applied with four stocking rates, on the above‐ground phytomass of veld was determined over four years.
  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...
