  1. 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...
  2. The erodibility of some soil series In the pineapple-producing coastal area of the eastern Cape

    The erodibility of some soil series In the pineapple-producing coastal area of the eastern Cape

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    A rotating-boom rainfall simulator was used to measure soil losses from eight soil series falling within five morphologically dissimilar soil forms, i.e. Bonheim, Glenrosa, Kroonstad, Mayo and Oakleaf. The data obtained were used to calculate the soil erodibility factor (K)...
  3. Factors Affecting Soil Phosphate Distribution and Reactions in Cape Forest Soils

    Item type: Journal Article • Journal: South African Forestry Journal
    The amounts of various forms of phosphate in some Cape soils and the adsorption of phosphate by these soils were investigated. The levels were low and only 2% was in available form. The major fraction of phosphate in the soil...
  4. 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,...
  5. 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...
  6. The Influence of Site Factors on the Foliar Nutrient Content of <em>Eucalyptus grandis</em> in Natal

    Item type: Journal Article • Journal: South African Forestry Journal
    Although foliar analysis is commonly used to diagnose the nutritional status of trees and their ability to respond to fertilising, it is also a measure of site type and quality. The availability of nutrients in the soil varies with climatic...
  7. Site Evaluation in Black Wattle with Special Reference to Soil Factors

    Item type: Journal Article • Journal: South African Forestry Journal
    Together with climate, soil characteristics are the most important factors affecting tree growth. However, the attempts in many site evaluation studies to establish a direct relationship between soil factors and tree growth have not been very successful, the exception being...
  8. 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...
  9. 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...
  10. The Hydrological Effects of a Wildfire in a Eucalypt Afforested Catchment

    Item type: Journal Article • Journal: South African Forestry Journal
    A high-intensity wildfire through a humid, upland catchment which was partially afforested to Eucalyptus fastigata, markedly increased stormflows and caused high soil losses off the afforested slopes. Total streamflow yield was unchanged but baseflow was reduced after the fire. The...
