  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. Litterfall and Nutrient Release in Mature <em>Pinus radiata</em> in the South-western Cape

    Item type: Journal Article • Journal: South African Forestry Journal
    Fast-growing plantations of conifers have replaced areas of mediterranean shrubland in the south-western Cape. This study arises from the need to quantify the impacts of major changes in primary productivity, litterfall, and nutrient cycling in terms of the site utilisation...
  3. Productivity of <em>Eucalyptus regnans</em> Forest Regenerating after Bushfire

    Item type: Journal Article • Journal: South African Forestry Journal
    A natural forest of mountain ash was clearfelled in 1983 and burned by bushfire immediately after logging. The resulting natural regeneration has high productivity, with a mean volume increment close to 50 m3/ha per year, mean rate of biomass accumulation...
  4. Regeneration Procedures of <em>Pinus radiata</em> in the Southern Cape Province

    Item type: Journal Article • Journal: South African Forestry Journal
    Part 2 of the series of papers dealing with the regeneration ofPinus radiata in the Southern Cape discusses the effect of the experimental treatments on the distribution of nutrient elements, more particularly to estimate the impact of treatments on changes...
  5. The influence of an <em>Acacia karroo</em> tree on grass production in its vicinity

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The investigation was concerned with the impact of an Acacia karroo tree on the productivity of the surrounding herbaceous layer.
  6. A model for the evaluation of different production strategies for animal production from rangeland in developing areas: An overview

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    An interactive user‐friendly computer package is being developed to assist planners and managers with the evaluation of different livestock production strategies in semi‐arid regions. It comprises a hierarchy of simulation models that predict over time the effects of past and...
  7. Genotypic tolerance of selected dry bean (<em>Phaseolus vulgaris</em> L.) cultivar s to soluble Al and to acid, low P soil conditions

    Genotypic tolerance of selected dry bean (<em>Phaseolus vulgaris</em> L.) cultivar s to soluble Al and to acid, low P soil conditions

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Twelve dry bean cultivare were grown for seven days on filter paper soaked with nutrient solution containing a range of up to 10 mmol Al dm−3. Differential response to Al toxicity, measured as taproot elongation, occurred at Al concentrations of...
  8. Aluminium toxicity and induced nutrient disorders involving the uptake and transport of P, K, Ca and Mg in <em>Zea mays</em> L.

    Aluminium toxicity and induced nutrient disorders involving the uptake and transport of P, K, Ca and Mg in <em>Zea mays</em> L.

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Chemical analysis of plant fractions of maize cultivars TX 24 and HL 1 grown in liquid culture containing Al showed that the action of Al was directed at the uptake of Ca and Mg and the transport of P and...
  9. Seasonal uptake of phosphorus, potassium, calcium and magnesium by young peach trees

    Seasonal uptake of phosphorus, potassium, calcium and magnesium by young peach trees

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Two-year-old peach trees, grown in sand culture were destructively sampled over a period of 14 months, to determine the uptake of phosphorus, potassium, calcium and magnesium in the new growth (leaves, fruit and new shoots) and in the permanent structure...
