  1. Microbial community function and structure on coal mine discard under rehabilitation

    Microbial community function and structure on coal mine discard under rehabilitation

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The rehabilitation of coal mine discard is problematic, especially since the lack of measures to evaluate the success of rehabilitation in terms of the self-sustainability of soil ecosystems established on these sites. In this study, the potential for using microbial...
  2. The effect of canola (<em>Brassica napus</em>) as a biofumigant on soil microbial communities and plant vitality: a pot study

    The effect of canola (<em>Brassica napus</em>) as a biofumigant on soil microbial communities and plant vitality: a pot study

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Canola (Brassica napus) may be incorporated into soil as a biofumigant for control of pathogens such as Sclerotinia sclerotiorum. Yet, the effect of biofumigants on natural microbial communities required to maintain soil functions is still unclear. A pot experiment with...
  3. Evaluering van die effek van industriële uitvloeisels op grondbiodegradasie en ontkieming met behulp van mikrobiologiese aktiwiteitsbepalings en ontkiemingstudies

    Evaluering van die effek van industriële uitvloeisels op grondbiodegradasie en ontkieming met behulp van mikrobiologiese aktiwiteitsbepalings en ontkiemingstudies

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Die bydrae van grondmikro-organismes tot biologiese aktiwiteite in die grand is baie belangrik, veral met betrekking tot hul metaboliese aktiwiteite, asook hul rol in energievloei en voedingsiklusse van, bv. C, N, P, S, Fe, Mn, en Si. 'n Versteuring van...
  4. DECOMPOSITION IN FRESHWATER ECOSYSTEMS

    DECOMPOSITION IN FRESHWATER ECOSYSTEMS

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    This review examines the sources and composition of organic matter and the decomposition of particulate and dissolved organic matter (POM and DOM) in freshwater ecosystems. The main points to emerge from the review are listed below.
  5. DECOMPOSITION IN PELAGIC MARINE ECOSYSTEMS

    DECOMPOSITION IN PELAGIC MARINE ECOSYSTEMS

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    During the decomposition of plant detritus, complex microbial successions develop which are dominated in the early stages by a number of distinct bacterial morphotypes. The microheterotrophic community rapidly becomes heterogenous and may include cyanobacteria, fungi, yeasts and bactivorous protozoans.
  6. Influence of residual manure on selected nutrient elements and microbial composition of soil under long-term crop rotation

    Influence of residual manure on selected nutrient elements and microbial composition of soil under long-term crop rotation

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    A study was conducted on a long-term field experiment at the University of Pretoria, South Africa, that was established in 1939. The aim was to investigate the effects of residual manure on the characteristics of the total and microbial biomass...
  7. Soil nutrient contents, microbial properties and maize yield under long-term legume-based crop rotation and fertilization: a comparison of residual effect of manure and NPK fertilizers

    Soil nutrient contents, microbial properties and maize yield under long-term legume-based crop rotation and fertilization: a comparison of residual effect of manure and NPK fertilizers

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    A study was conducted in a field experiment that has been ongoing for over 60 years at the University of Pretoria, South Africa. The aim was to compare the residual effects of manure and NPK fertilizers on selected soil nutrients,...
  8. Soil properties changes after short-term livestock exclusion in “degraded” communally managed rangelands in the western Bophirima District, South Africa

    Soil properties changes after short-term livestock exclusion in “degraded” communally managed rangelands in the western Bophirima District, South Africa

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Livestock grazing and detrimental overgrazing are commonly associated with severe rangeland degradation particularly in communally managed pastoral systems in South Africa. Effects of grazing exclusion on vegetation are well documented, but there is a dearth of quantitative research conducted in...
  9. AIDS communications through social networks: catalyst for behaviour changes in Uganda

    AIDS communications through social networks: catalyst for behaviour changes in Uganda

    Item type: Journal Article • Journal: African Journal of AIDS Research
    Objective: To investigate distinctive communications through social networks which may be associated with population behaviour changes and HIV prevalence declines in Uganda compared to other countries.
  10. On the dynamics of demersal fish assemblages off Namibia in the 1990s

    On the dynamics of demersal fish assemblages off Namibia in the 1990s

    Item type: Journal Article • Journal: South African Journal of Marine Science
    Demersal fish surveys carried out off Namibia from 1990 to 2000 were used to study the dynamics of demersal fish assemblages on the shelf and upper slope. The study was performed on each major assemblage, i.e. over the shelf (100–300...
