An ecological study into the possible reclamation value of reedbeds in a coal mine wetland system in Kwazulu-Natal
(North-West University, 2004)
The single biggest environmental problem facing the coalmine industry today is the high acid
concentration in mine runoff water. After pollution prevention and effluent reuse, reclamation is the
most important component ...
Evaluation of selected soil properties in semi-arid communal rangelands in the Western Bophirima district, South Africa
(North-West University, 2007)
Concerns were raised over the past decades, on the degradation condition of arid and semi-arid range lands in South Africa, mainly in areas under communal land management. Baseline information on soil quality is essential ...
The assessment of soil microbial and plant physiological changes during the treatment of soil containing bromacil, tebuthiuron and ethidimuron
(North-West University, 2005)
Increased amounts of pesticide production and application of pesticides for agriculture,
plant protection and animal health has resulted in soil, water and air pollution,
consequently relating a serious risk to the ...
The assessment of topsoil degradation on rehabilitated coal discard dumps
(North-West University, 2003)
This study investigates coal discard cover soil fertility and its potential for
degradation, particularly in terms of its salinisation and acidification potential. Seven
rehabilitated coal discard dumps in the Witbank, ...
Towards the successful application of diatom-based biomonitoring in South Africa
(North-West University, 2006)
Water is a scarce and precious resource in South Africa. Not only is the quality and quantity
of water available limited by climatic conditions but these resources are often impacted by domestic
and industrial effluents, ...
Measuring rehabilitation success of coal mining disturbed areas : a spatial and temporal investigation into the use of soil microbial properties as assessment criteria
(North-West University, 2007)
The rehabilitation of degraded soils, such as those associated with post-mining sites, requires
knowledge of the soil ecosystem and its physical, chemical, and biological composition in order for
rehabilitation efforts ...
Evaluation of predictive models for pesticide behaviour in South African soils
(North-West University, 2009)
The re-evaluation of pesticide use patterns is a high priority internationally. The process has led to a reduction in the numbers of pesticides allowed for use in many countries. This withdrawal of pesticides is aimed at ...
The effect of pre-ozonation on the physical characteristics of raw water and natural organic matter (NOM) in raw water from different South African water resources
(North-West University, 2006)
Research in the use of ozone in water treatment conducted by many authors support the idea that the nature and characteristics of natural organic matter (NOM) present in raw water determines the
efficiency of ozonation ...
Quantifying the effect of different irrigation volumes on cut-rose production
(North-West University, 2004)
Rose plants in general, and especially rose plants of the Hybrid Tea cultivar, Grand Gala, are known for their demanding nature with respect to fertiliser, irradiance levels, night and day temperatures, carbon dioxide ...
The use of different ecosystem components as indicators of ecosystem development during platinum mine tailings rehabilitation
(North-West University, 2005)
Platinum mining activities contribute substantially to South Africa's economy since it exceeded gold as economical contributor in 2001. Mining activities contribute to large
amounts of waste production in the form of ...
