  1. Population fluctuations of <em>Cerithidea decollata</em> (Gastropoda: Potamididae) in mangrove habitats of the St Lucia Estuary, South Africa

    Population fluctuations of <em>Cerithidea decollata</em> (Gastropoda: Potamididae) in mangrove habitats of the St Lucia Estuary, South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    Mangrove macrobenthos species are used as ecological indicators as they are sensitive to changes in sediment properties. In this study, the population density of the common mangrove whelk Cerithidea decollata was assessed during different environmental conditions in the St Lucia...
  2. Die invloed van drie tussenrybewerkingsmetodes op opbrengs en chemiese samestelling van droëlandlusern op die oos‐transvaalse hoëveld.

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Drie tussenrybewerkingsmetodes, skeurploeg (40 — 50 cm diep) skoffel (5 — H) cm diep) en kontrole (geen bewerking) is gedurende die 1982/83 en 1983/84 groeiseisoene in ‘n bestaande lusernstand uitgevoer. Hierdie lusern was in 0,9 m rye gevestig. Tye van...
  3. A comparison of three methods of soil water content determination

    A comparison of three methods of soil water content determination

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    In forestry the need to manage plantations on a sustainable site-specific basis requires the understanding and management of any growth limiting factors. Soil water regime is a factor considered to be of prime importance with respect to explaining differences in...
  4. Die invloed van die voginhoud op die dopbaarheid van sonneblomsaad

    Die invloed van die voginhoud op die dopbaarheid van sonneblomsaad

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Die voginhoud van sonneblomsaad (Helianthus annuns L.) wat vir persing gebruik word, wissel tussen 5.5% (ongeveer die laagste inhoud waartoe saad natuurlik droog) en 10% (die hoogste toelaatbare inhoud vir berging). Die doel van die ondersoek was om vas te...
  5. Germination strategies of Strandveld Succulent Karoo plant species for revegetation purposes: III Effect of relative humidity and storage site on seed viability

    Germination strategies of Strandveld Succulent Karoo plant species for revegetation purposes: III Effect of relative humidity and storage site on seed viability

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Changes in seed viability owing to fluctuations in environmental conditions (temperature and relative humidity) are crucial factors to consider during post-mining revegetation efforts in the Strandveld Succulent Karoo. The effect of relative humidity and storage site on seed viability was...
  6. Significance of kernel moisture content in determination of Hagberg Falling Number in wheat

    Significance of kernel moisture content in determination of Hagberg Falling Number in wheat

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The effect of early termination of kernel filling (early harvest) on the Hagberg Falling Number (HFN) was investigated over a four-year period. Selected South African wheat cultivars were harvested at different stages of kernel development, determined by kernel moisture content...
  7. Variation in Wood Properties of <em>Eucalyptus nitens</em> in a Provenance Trial on the Eastern Transvaal Highveld in South Africa

    Item type: Journal Article • Journal: South African Forestry Journal
    Eucalyptus nitens is one of the four important cold-tolerant eucalypts grown for mining timber and pulpwood on the eastern Transvaal highveld in South Africa. In 1983 an active genetic improvement programme was initiated to improve growth rate, stem form and...
  8. Equilibrium sorption isotherms of <em>Moringa oleifera</em> leaves at different temperatures

    Equilibrium sorption isotherms of <em>Moringa oleifera</em> leaves at different temperatures

    Adsorption and desorption isotherms for Moringa oleifera leaves were investigated using concentrated H2SO4 solutions to vary the micro-climate over different temperatures (27, 32, 37°C) and water activity (aw) (0.1–0.8). Plots of equilibrium moisture content (EMC) against aw were used to...
  9. Development of a charcoal-fuelled dryer for the production of organic fertilizer from hog waste

    Development of a charcoal-fuelled dryer for the production of organic fertilizer from hog waste

    The negligence of livestock farmers regarding waste disposal and inadequate waste control facilities are becoming a serious health and environmental hazard. In this study, a charcoal-fuelled dryer was developed to eliminate the moisture content in hog waste for easy conversion...
  10. The impact of log surface damage caused by harvester <em>Eucalyptus</em> debarking on pulp value recovery

    The impact of log surface damage caused by harvester <em>Eucalyptus</em> debarking on pulp value recovery

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Mechanised harvesting operations are growing in popularity in South Africa, as motor-manual and manual harvesting operations pose significant health and safety risks to workers. Potential damage inflicted by single-grip harvester feed rollers and delimbing knives on the log surface during...
