  1. 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...
  2. Effect of exchangeable sodium and phosphogypsum on the hydraulic properties of several South African soils

    Effect of exchangeable sodium and phosphogypsum on the hydraulic properties of several South African soils

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The susceptibility of soils to the deleterious effects of sodicity was assessed for samples which varied with respect to physical, mineralogical and other properties. For this purpose soil samples were collected from different locations in South Africa. The effect of...
  3. Characterizing the hydraulic properties of a semi-arid catchment by means of sorptivity measurements and scaling theory

    Characterizing the hydraulic properties of a semi-arid catchment by means of sorptivity measurements and scaling theory

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The variability of soil sorptivity within a semi-arid catchment was investigated on a macro- (28 ha) and microscale (16 m2). In the macroscale study, sorptivity was measured at 176 sites using a falling hydraulic head technique. The mean sorptivity of...
  4. Rate of dissolution of gypsum from different sources and its effect on water infiltration of soil

    Rate of dissolution of gypsum from different sources and its effect on water infiltration of soil

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Five sources of gypsum (pure, mined and three industrial) were pressed into pellets and their dissolution rate when suspended in water compared by measuring electrical conductivity of the stirred solution. Pellets of industrial phosphogypsum from Phalaborwa, Potchefstroom and Richards Bay...
  5. 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...
  6. Soil compaction under sugar cane (<em>Saccharum hybrid</em> sp.) cropping and mechanization in Mauritius

    Soil compaction under sugar cane (<em>Saccharum hybrid</em> sp.) cropping and mechanization in Mauritius

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Farm machinery is increasingly used in sugar cane production in Mauritius and is expected to cause soil compaction. A study was undertaken to ascertain whether the five major cane-growing soil groups of Mauritius were being compacted as a result of...
  7. Winter cover crops effects on soil strength, infiltration and water retention in a sandy loam Oakleaf soil in Eastern Cape, South Africa

    Winter cover crops effects on soil strength, infiltration and water retention in a sandy loam Oakleaf soil in Eastern Cape, South Africa

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    There is substantial evidence that cover crops increase soil fertility and plant nutrition but the few studies concerning soil physical properties are conflicting. This study determined the effects of monocultures of vetch (Vicia dasycarpa L.), lupin (Lupinus angustifolius L.), oats...
  8. Effect of three grazing intensities on selected soil properties in semi‐arid west Texas

    Effect of three grazing intensities on selected soil properties in semi‐arid west Texas

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Soils in the study, carried out in the Texas Trans‐Pecos region, were fine‐loamy, mixed, thermic Aridic Calciustolls; fine‐loamy, mixed, thermic Aridic Ustochrepts; and fine, mixed, thermic Typic Chromusterts. Our primary objective was to determine the effect of three grazing intensities...
  9. Characteristics and management options of crusting soils in a smallholder farming area of the Zambezi metamorphic belt in northern Zimbabwe

    Characteristics and management options of crusting soils in a smallholder farming area of the Zambezi metamorphic belt in northern Zimbabwe

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Crusting and surface-sealing soils present productivity challenges to smallholder farmers despite their high inherent fertility. Crop production on crusting soils is costly due to unfavourable conditions such as surface capping and compaction, which hinder crop emergence. A study was conducted...
  10. Endometrial cancer with bone marrow metastases: a management dilemma

    Endometrial cancer with bone marrow metastases: a management dilemma

    Item type: Journal Article • Journal: Southern African Journal of Gynaecological Oncology
    A case is presented of a 67-year-old woman referred to the authors’ institution with endometrioid endometrial cancer with a leucoerythroblastic blood film and marked thrombocytopenia. On further evaluation, it was confirmed that she had grade 3 endometrial cancer with bone...
