  1. 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,...
  2. Are Pine Plantations “Inhospitable Seas” around Remnant Native Habitat within South-western Cape Forestry Areas?

    Item type: Journal Article • Journal: South African Forestry Journal
    Some areas of forestry estates, including unplantable ones, may be zoned and managed for nature conservation. This paper is an analysis of the results of studies of plants, birds and small mammals at Jonkershoek, Stellenbosch, to determine whether pine plantations...
  3. Pine litter as substrate for propagation of vegetable transplants in trays

    Pine litter as substrate for propagation of vegetable transplants in trays

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The study evaluates the potential of pine litter for use as a substrate in the propagation of vegetable transplants in trays. Sub-optimum pH and electrical conductivity of pine litter were addressed by incorporating 10% feedlot manure by volume. The water...
  4. Effect of pine bark goat manure medium on seedling growth and N, P, K concentration of various vegetables

    Effect of pine bark goat manure medium on seedling growth and N, P, K concentration of various vegetables

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Pine bark compost is the medium of choice for seedling growers in South Africa due to its availability, low cost and good physical properties. However, it is acidic, has low electrical conductivity (EC) and nutrient content such that fortification and...
  5. Post establishment survival of <em>Pinus patula</em> in Mpumalanga, one year after planting

    Post establishment survival of <em>Pinus patula</em> in Mpumalanga, one year after planting

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    Recent evidence indicated that the pathogen Fusarium circinatum might be contributing significantly to post-planting mortality. Consequently, sixteen experimental sample plots, widely distributed over many localities in Mpumalanga, were established over two growing seasons to quantify the extent of pest and...
  6. Clonal propagation and storage of subtropical pines in Queensland, Australia

    Clonal propagation and storage of subtropical pines in Queensland, Australia

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    Clonal forestry is the approach used for deployment of Pinus elliottii × P. caribaea hybrids in Queensland, Australia. Clonal forestry relies on the ability to maintain juvenility of stock plants while selections are made in field tests, so that genetic...
  7. CCA—treated Laminated Railway Sleepers and Telephone Cross-arms

    Item type: Journal Article • Journal: South African Forestry Journal
    A non-conventional process for the manufacturing of laminated pine railway sleepers and telephone cross-arms, involving the treatment of laminations with copper-chrome-arsenic (CCA) preservatives before gluing and assembly, was investigated.
  8. “New” pine species and hybrids: Is there still potential?

    “New” pine species and hybrids: Is there still potential?

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    Many tree breeding programs are moving into advanced generation breeding, and breeders need to ensure continued gains from these programs. The potential of infusing genetic material into existing breeding programs, the introduction of “new” species, and hybridisation are discussed as...
  9. Stand stability in pines : An important silvicultural criterion for the evaluation of thinnings and the development of thinning regimes

    Stand stability in pines : An important silvicultural criterion for the evaluation of thinnings and the development of thinning regimes

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    This article deals with the role played by the stability factor (SF) in the evaluation ofthinnings in fastgrowing, even-aged pine stands. It also illustrates how the stability factor is influenced by thinnings and site over time. The SF is expressed...
  10. Grade verification of SA pine — bending, modulus of rupture, modulus of elasticity, tension and compression

    Grade verification of SA pine — bending, modulus of rupture, modulus of elasticity, tension and compression

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    The last verification of SA pine timber strengths was done in the early 1980s. Uses of the pine logs and the rotation periods have changed. This investigation was undertaken to verify the visual grade 5 grading rules of SANS 1783-2...
