  1. Impact of Wood Quality Assessments on Future Fibre Resources in the Pulp and Paper-making Industry

    Item type: Journal Article • Journal: South African Forestry Journal
    Recent evidence from research in Europe has indicated that individual trees can be sampled for their pulping properties by the removal of small quantities (5–50 g) of wood at about breast height (1,3 m above ground). Work began at Sappi's...
  2. A Comparison of the kraft pulp properties of P. <em>elliottii</em> and the <em>P. elliottii</em> x <em>P. caribaea</em> var. <em>hondurensis</em> hybrid grown in Queensland, Australia

    A Comparison of the kraft pulp properties of P. <em>elliottii</em> and the <em>P. elliottii</em> x <em>P. caribaea</em> var. <em>hondurensis</em> hybrid grown in Queensland, Australia

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    The interspecific hybrid between P. elliottii var. elliottii and P. caribaea var. hondurensis has recently been accepted for planting operationally as an alternative to P. elliottii by Sappi in South Africa. Some concerns have been expressed as to the suitability...
  3. Rapid estimation of kraft pulp yield and lignin in <em>Eucalyptus camaldulensis</em> and <em>Leucaena leucocephala</em> by diffuse reflectance near-infrared spectroscopy (NIRS)

    Rapid estimation of kraft pulp yield and lignin in <em>Eucalyptus camaldulensis</em> and <em>Leucaena leucocephala</em> by diffuse reflectance near-infrared spectroscopy (NIRS)

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Near-infrared spectroscopy has been used to develop calibration models for the rapid determination of kraft pulp yield (KPY) and lignin in Eucalyptus camaldulensis and Leucaena leucocephala. The correlation coefficient for cross-validation is 0.90 for KPY and 0.95 for lignin prediction,...
  4. The use of near-infrared scanning for the prediction of pulp yield and chemical properties of <em>Pinus patula</em> in the Mpumalanga escarpment area of South Africa

    The use of near-infrared scanning for the prediction of pulp yield and chemical properties of <em>Pinus patula</em> in the Mpumalanga escarpment area of South Africa

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Near-infrared (NIR) scanning technology is regarded as a potential tool for rapid determination of wood properties, which can substitute time-consuming and costly traditional methods. Pinus patula is the most important softwood species in South Africa, and this study is aimed...
  5. Measurement of cellulose content, Kraft pulp yield and basic density in eucalypt woodmeal using multisite and multispecies near infra-red spectroscopic calibrations

    Measurement of cellulose content, Kraft pulp yield and basic density in eucalypt woodmeal using multisite and multispecies near infra-red spectroscopic calibrations

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Previous descriptions of multisite and multispecies near infra-red (NIR) spectroscopic calibrations for predicting cellulose content (CC) and Kraft pulp yield (KPY) in eucalypt woodmeal demonstrated that large, single calibrations provide precise predictions for a wide range of sites and species...
  6. Developing and evaluating a multisite and multispecies NIR calibration for the prediction of Kraft pulp yield in eucalypts

    Developing and evaluating a multisite and multispecies NIR calibration for the prediction of Kraft pulp yield in eucalypts

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Over recent years the application of near infra-red (NIR) spectroscopy to the prediction of wood properties has been demonstrated in many proof-of-concept studies. Previous work has demonstrated that NIR measurements can be used to predict basic density from woodmeal, chainsaw...
  7. Effect of phosphorus and potassium fertiliser on tree growth and dry timber production of <em>Pinus patula</em> on gabbro-derived soils in Swaziland

    Effect of phosphorus and potassium fertiliser on tree growth and dry timber production of <em>Pinus patula</em> on gabbro-derived soils in Swaziland

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    A trial designed to determine the optimum timing and rate of application of phosphorus (P) and potassium (K) fertiliser, to mitigate a growth decline observed in P. patula stands located on the gabbro-derived soils (underlying 13% of the plantation area)...
  8. Wood anatomical and chemical properties related to the pulpability of <em>Eucalyptus globulus</em>: a review

    Wood anatomical and chemical properties related to the pulpability of <em>Eucalyptus globulus</em>: a review

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Eucalyptus globulus is one of the most important hardwood species used by the pulp and paper industry due to its high pulp yield, high wood density, excellent fibre quality and good handsheet properties. However, the wood is a highly variable...
  9. Sawn-timber and kraft pulp properties of <em>Pinus elliottii</em> × <em>Pinus caribaea</em> var. <em>hondurensis</em> and <em>Pinus patula</em> × <em>Pinus tecunumanii</em> hybrids and their parental species

    Sawn-timber and kraft pulp properties of <em>Pinus elliottii</em> × <em>Pinus caribaea</em> var. <em>hondurensis</em> and <em>Pinus patula</em> × <em>Pinus tecunumanii</em> hybrids and their parental species

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    A study was undertaken to evaluate the quality of the timber produced by Pinus elliottii × Pinus caribaea var. hondurensis (PECH) and the Pinus patula × Pinus tecunumanii low elevation (PPTL) and high elevation (PPTH) hybrids and their parent species...
  10. Modelling Diameter and Height Distributions through Dispersion Statistics in Even-aged Pine Plantations

    Item type: Journal Article • Journal: South African Forestry Journal
    Diameter and height distribution recovery, in combination with standlevel projection modelling, is generally used in Southern Africa for predicting growth and yield in even-aged pine plantations. A different approach for modelling diameter and height distributions for five pine species commercially...
