  1. Timber Harvesting in South Africa—Past, Present, Future

    Item type: Journal Article • Journal: South African Forestry Journal
    After a short description of South African timber harvesting practices in the past, the present situation in terms of machine population and the current harvesting and extraction methods is discussed in more detail.
  2. Cable Yarding in Southern Africa: An Analysis of its Productivity and Possible Procedure for its Improvement

    Item type: Journal Article • Journal: South African Forestry Journal
    The demand for timber in southern Africa is increasing and this is resulting in the afforestation of areas which require cable yarding when harvested. The demand for cable yarders, essentially fixed skylines, is therefore increasing rapidly. Stress is being placed...
  3. The Impact of Harvesting Operations on Timber Quality: Causes and Remedies

    Item type: Journal Article • Journal: South African Forestry Journal
    Forests are devastated daily to satisfy the world's timber demands. Tropical forests throughout the world are exploited and endangered. An obligation therefore exists to avoid damage to timber and minimise waste wherever possible.
  4. Patterns of selection of <em>Acacia karroo</em> by goats and changes in tannin levels and <em>in vitro</em> digestibility following defoliation

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Patterns of browse selection by Boer goats in a representative Acacia karroo community in the eastern Cape were studied. The rate of intake of browse was positively related to the leaf mass per unit length of the shoot. The ease...
  5. Some observations on rodent and antelope damage in commercial forest plantations

    Some observations on rodent and antelope damage in commercial forest plantations

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The impact of various weeding and site-preparation treatments on Acacia mearnsii and Pinus patula damage by mammalian pests was assessed. Browsing by small antelope on Acacia mearnsii was significantly less in areas where harvesting residues had been retained rather than...
  6. The development of harvesting schedules and post-harvesting management practices relative to oil yield of <em>Eriocephalus punctulatus</em>

    The development of harvesting schedules and post-harvesting management practices relative to oil yield of <em>Eriocephalus punctulatus</em>

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The first phase in the domestication programme of Eriocephalus punctulatus involved establishing how this crop could be harvested without adversely affecting plant vigour and longevity. The second phase of the domestication programme was the development of harvesting schedules that would...
  7. Effect of planting and harvesting dates on fungus-growing termite infestations in maize

    Effect of planting and harvesting dates on fungus-growing termite infestations in maize

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Fungus-growing termites (Microtermes spp. and Allodontermes spp.) damage maize roots and cause lodging. The pattern of attack, incidence of lodging, and the effect of planting and harvesting dates on damage and yield were studied in field trials over five seasons...
  8. <em>Amaranthus tricolor</em> L. leaf yields affected by salinity, harvesting stage and harvesting methods

    <em>Amaranthus tricolor</em> L. leaf yields affected by salinity, harvesting stage and harvesting methods

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Single Amaranthus tricolor seedlings were transplanted into containers filled with 5 I river sand and were fertigated with a ‘drain to waste’ system. Plants were grown in the open under warm summer conditions. Four to six daily applications of nutrient...
  9. Evaluating the maize production potential of a semi-arid ecotope with four production techniques

    Evaluating the maize production potential of a semi-arid ecotope with four production techniques

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Water conservation production techniques are needed to boost crop production in semi-arid areas. The in-field rainwater harvesting (IRWH) technique has been developed for this purpose, and found to be successful on clay and duplex soils, but has not yet been...
  10. Soil compaction under sugar cane (<em>Saccharum hybrid</em> sp.) cropping and mechanization in Mauritius

    Soil compaction under sugar cane (<em>Saccharum hybrid</em> sp.) cropping and mechanization in Mauritius

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Farm machinery is increasingly used in sugar cane production in Mauritius and is expected to cause soil compaction. A study was undertaken to ascertain whether the five major cane-growing soil groups of Mauritius were being compacted as a result of...
