  1. 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)...
  2. An inexpensive, portable rain simulator: construction and test data

    An inexpensive, portable rain simulator: construction and test data

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Construction details of an inexpensive, portable rain simulator are given. The dismountable components are easily transported on a light truck. The flat spray nozzles used produced rain with a >90% coefficient of uniformity over a 1-m2 test plot. Drop sizes...
  3. Effect of the amount of surface maize residue on infiltration and soil loss from a clay loam soil

    Effect of the amount of surface maize residue on infiltration and soil loss from a clay loam soil

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Six levels of maize stover, expressed as percentage ground cover (0–75%) were compared under a rainfall simulator to assess the effect of surface residues on infiltration and soil loss on a clay loam soil with a 3,5% slope. Increasing the...
  4. Effect of simulated acid rain and sulphur nutrition on the growth, sulphate and cation content of <em>Bromus diandrus</em> Roth.

    Effect of simulated acid rain and sulphur nutrition on the growth, sulphate and cation content of <em>Bromus diandrus</em> Roth.

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Bromus diandrus seedlings were grown in sand culture under greenhouse conditions, using a two factor randomized block design. Two levels of sulphur nutrition (with and without) and three acid rain treatments were applied. The plants were harvested 45 days after...
  5. Modelling the potential distribution of Karnal bunt of wheat in South Africa

    Modelling the potential distribution of Karnal bunt of wheat in South Africa

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The objective of this paper was to use established meteorological modelling methods to determine wheat growing regions in South Africa that would be favourable to infection by Tilletia indica, and to determine whether irrigation schedules influence climatic suitability for the...
  6. Physiological traits associated with drought tolerance in bread wheat (<em>Triticum aestivum</em> L.) under tropical conditions

    Physiological traits associated with drought tolerance in bread wheat (<em>Triticum aestivum</em> L.) under tropical conditions

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Although it is generally accepted that drought tolerance is a critical agronomic trait, efficient and predictable improvement in drought tolerance in bread wheat (Triticum aestivum L.), in varying drought stress conditions, has not been fully achieved. This study aimed at...
  7. Using rain-use efficiency to explore livestock production trends in rangelands in the Transkei, South Africa

    Using rain-use efficiency to explore livestock production trends in rangelands in the Transkei, South Africa

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    We qualitatively describe the condition of communally managed rangelands in the Transkei, South Africa, using GIS and high resolution near-infrared imagery. Using livestock census data from 28 magisterial districts in the Transkei, we explored the trends in livestock biomass from...
  8. Variation in seed rain from <em>Widdringtonia whytei</em> growing in different conditions on Mulanje Mountain in Malawi

    Variation in seed rain from <em>Widdringtonia whytei</em> growing in different conditions on Mulanje Mountain in Malawi

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Mulanje Mountain is one of the examples of tropical montane landscapes with plant populations varying in size from small fragments of less than 1 ha to riverine strips and stands of more than 100 ha. Seed availability is a potential...
  9. Airway skills training using a human patient simulator

    Airway skills training using a human patient simulator

    Item type: Journal Article • Journal: Southern African Journal of Anaesthesia and Analgesia
    Background: Airway skills education is important for the safe and effective care of patients. Interns often encounter critical airway situations. Their ability to cope derives from the recall of formal lectures and tutorials, as well as accumulated experience. We tested...
  10. The development of a scoring tool for the measurement of performance in managing hypotension and intra-operative cardiac arrest during spinal anaesthesia for caesarean section

    The development of a scoring tool for the measurement of performance in managing hypotension and intra-operative cardiac arrest during spinal anaesthesia for caesarean section

    Item type: Journal Article • Journal: Southern African Journal of Anaesthesia and Analgesia
    Background: At level one hospitals in South Africa a high annual number of maternal deaths occur due to the unrecognised/untreated complications of spinal anaesthesia. The authors developed a clinical scenario and scoring system to measure intern performance in managing hypotension...
