  1. The effect of various tillage methods on soil and water losses from maize lands

    The effect of various tillage methods on soil and water losses from maize lands

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Natural runoff plots on which maize was produced were laid out at Cedara on a well-drained clay loam Doveton soil and showed, over a six-year period, the benefits to be gained from adopting conservation tillage practices. The four tillage and...
  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. Factors affecting runoff and soil loss under simulated rainfall on a sandy Bainsvlei Amalia soil

    Factors affecting runoff and soil loss under simulated rainfall on a sandy Bainsvlei Amalia soil

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    This study was conducted on a long-term tillage experiment that was designed to evaluate appropriate tillage practices for sustainable dryland crop production. Measurements of runoff and soil loss were conducted on a sandy Bainsvlei Amalia soil (88.0% sand, 3.6% silt,...
  4. Tillage-crop residue management and rainfall-runoff relationships for the Alemaya catchment in Eastern Ethiopia

    Tillage-crop residue management and rainfall-runoff relationships for the Alemaya catchment in Eastern Ethiopia

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    A field study was conducted in the Alemaya catchment, Eastern Ethiopia, with the objective of determining the effect of tillage practices, crop reside cover and rainfall characteristics on runoff during two rainfall seasons on a clayey Regosol with 5% slope...
  5. Evaluation of soil conservation measures on a highly erodible soil in the Free State province, South Africa

    Evaluation of soil conservation measures on a highly erodible soil in the Free State province, South Africa

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Soil erosion is a problem in South Africa, and is exacerbated by poor land use practices and erodible soils. Several methods are available to address the problem and a runoff trial was conducted over four rainfall seasons on an erodible,...
  6. RATE OF EROSION IN THE CATCHMENT OF THE BULBERGFONTEIN DAM NEAR REDDERSBURG IN THE ORANGE FREE STATE

    RATE OF EROSION IN THE CATCHMENT OF THE BULBERGFONTEIN DAM NEAR REDDERSBURG IN THE ORANGE FREE STATE

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    The volume of sediment in the Bulbergfontein Dam was computed after mapping the area of the dam and ascertaining the depth of the sediment by digging and augering. The watershed of the impoundment had been delimited by means of aerial...
  7. Quantification of the soil-water balance under different veld condition classes in a semi-arid climate

    Quantification of the soil-water balance under different veld condition classes in a semi-arid climate

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    The monthly herbage production, water-use efficiency (WUE: above-ground phytomass production per unit of evapotranspiration), surface runoff and soil loss were determined on grassland in three different ecological conditions, viz. poor, moderate and good, over a four year (1995/1996 to 1998/1999)...
