  1. Influence of Soil Organic Matter Content on the Responsiveness of <em>Eucalyptus grandis</em> to Nitrogen Fertiliser

    Item type: Journal Article • Journal: South African Forestry Journal
    It is widely recognised that the inherent nitrogen (N) mineralisation capacity of a soil is directly related to the organic matter content. Consequently, in estimating the N requirements of Eucalyptus grandis at planting this mineralisation potential must be taken into...
  2. The Relationship between Soil Water Status, Rainfall and the Growth of <em>Eucalyptus grandis</em>

    Item type: Journal Article • Journal: South African Forestry Journal
    Available soil water is recognised as the main factor influencing the growth of commercial plantations in southern Africa. This is of strategic importance as successive rotations of demanding species such as Eucalyptus grandis may be depleting the soil water reserves...
  3. Comparison of <em>Eucalyptus grandis</em> Provenances and Seed Orchards in a Frost Frequent Environment

    Item type: Journal Article • Journal: South African Forestry Journal
    An international provenance trial of Eucalyptus grandis was established in southern Florida in 1980 and measured for growth and frost-tolerance through 8,8 years. The trial compared 20 Australian provenances 1) among themselves and 2) with seed orchard stock from Florida...
  4. Effect of Initial Spacing and Thinning on Some Wood Properties of <em>Eucalyptus grandis</em>

    Item type: Journal Article • Journal: South African Forestry Journal
    A study was made of the effect of thinning intensity on wood density and some wood anatomical properties and their within-tree variation patterns, as well as the extent to which the development of growth-stress splits in logs and sawn boards...
  5. The Use of Roots to Test N, P and K Deficiencies in <em>Eucalyptus</em> Nutrition

    Item type: Journal Article • Journal: South African Forestry Journal
    Bioassays have been developed which can provide diagnostics of the nutritional status of trees. They measure the flux of N, P or Rb for K into roots from standard solutions where the rate of influx is inversely related to nutrient...
  6. The Effects of Phosphorus and Dolomitic Lime on the Production and Volumetrical Conversion Factors of <em>Eucalyptus grandis</em> Wood

    Item type: Journal Article • Journal: South African Forestry Journal
    The effects of phosphorus and dolomitic lime applications on the stacked wood volume, dry wood weight and form, bark and stacking factors of Eucalyptus grandis Hill ex Maiden trees are presented. The rates of phosphorus (0 kg, 200 kg and...
  7. The effect of harvesting operations, slash management and fertilisation on the growth of a <em>Eucalyptus</em> clonal hybrid on a sandy soil in Zululand, South Africa

    The effect of harvesting operations, slash management and fertilisation on the growth of a <em>Eucalyptus</em> clonal hybrid on a sandy soil in Zululand, South Africa

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    Harvesting operations during clearfelling and extraction of timber from commercial plantations result in many processes that may affect long-term site productivity such as soil compaction and residue manipulation. The objective of this work was to evaluate the effects of various...
  8. Kraft Pulping Properties of <em>Acacia mearnsii</em> and <em>Eucalyptus grandis</em> Grown in Zimbabwe

    Kraft Pulping Properties of <em>Acacia mearnsii</em> and <em>Eucalyptus grandis</em> Grown in Zimbabwe

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    Pulpwood samples from 8-year old Acacia mearnsii and Eucalyptus grandis plantations grown in Zimbabwe were evaluated for kraft pulping, bleaching and papermaking properties. The possibility of co-pulping the two species was also investigated.
  9. A Site-growth Study of <em>Eucalyptus grandis</em> in the Mpumalanga Escarpment Area

    A Site-growth Study of <em>Eucalyptus grandis</em> in the Mpumalanga Escarpment Area

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    A site-growth study was conducted on Eucalyptus grandis on the granitic soils of the Mpumalanga escarpment area. The objectives were twofold, namely to identify those site factors that can be related to the growth of the species, as well as...
  10. Predicted and realized genetic gain in <em>Eucalyptus grandis</em> breeding seedling orchard in Zimbabwe

    Predicted and realized genetic gain in <em>Eucalyptus grandis</em> breeding seedling orchard in Zimbabwe

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    Results are presented of a fourth generation breeding seedling orchard of Eucalyptus grandis Hill Maiden of 30 half-sib families. Measurements at one and half and five years were available. Analysis of one and half year data showed no significant differences...
