Environmental factors influencing the distribution hookworm infection in KwaZulu-Natal, South Africa [sic].
(1998)The aim of this study was to investigate the occurrence of the soil transmitted parasitic nematode Necator americanus ("Old World" hookworm) in soils of different texture in KwaZulu-Natal. The key questions being asked ... -
An evaluation of the use of organic amendments to ameliorate aluminium toxicity and phosphorus deficiency in an acid soil.
(2000)The effects of the additions of some commonly-available organic residues to an acid, P-deficient soil (typical of those used by small-scale farmers in KwaZulu-Natal) on soil pH, exchangeable and soil solution AI, P ... -
The effects of surface-applied poultry manure on top- and subsoil acidity and selected soil fertility characteristics.
(2001)The effects of surface applications of poultry manure on pH, exchangeable AI, exchangeable Al saturation and levels of available macronutrients in the surface and subsurface layers were investigated in some acid soils ... -
Effects of irrigation-induced salinity and sodicity on soil chemical and microbial properties and sugarcane yield.
(2001)The effects of irrigation-induced salinity and/or sodicity on sugarcane yield, and two growth parameters, namely stalk height and number of nodes per stalk , were investigated on a sugarcane estate in the Zimbabwean lowveld. ... -
Sorption and desorption of pyridine by Pahokee peat from hexadecane in the presence of organic co-solvents.
(2002)A study of the interactions of the specifically interacting organic compound pyridine with a model soil organic matter sorbent (Pahokee peat) was carried out from different nonaqueous organic liquid media, including neat ... -
An investigation of factors contributing to soil degradation under dairy farming in the Tsitsikamma.
(2002)Pasture-based dairy farming is the major land use in the Tsitsikamma region of the Eastern Cape. Permanent kikuyu grass (Pennisetum clandestinum) dominates pastures in the region. Kikuyu pastures do not, however, provide ... -
An evaluation of conventional and no-tillage systems on soil physical conditions.
(2002)The use of no-tillage (NT) system has increased in the past few years in South Africa, but its effects on soil physical conditions have not been adequately documented. This study was undertaken to ascertain these effects, ... -
Comparative effects of sugarcane monoculture on soil organic matter status and soil biological activity.
(2002)The effects of increasing periods under sugarcane monoculture (managed by preharvest burning) on soil organic matter content and related soil properties were investigated in the 0 to 10 cm layer of a sandy coastal Ochric ... -
Influence of land use on soil organic matter status, microbial biomass C and size and composition of earthworm communities in northern KwaZulu-Natal.
(2002)The effect of land management including undisturbed native forest, native grassland, sugarcane (preharvest burnt or green cane harvested), exotic forest (gum, pine or wattle), orchard crops (banana, orange and avocado) ... -
The characterisation of some South African water treatment residues and glasshouse pot experiments to investigate the potential of two residues for land disposal.
(2003)Water treatment residues (WTRs) are the by-product from the production of potable water. They consist mainly of the precipitated hydrous oxides of the treatment chemicals, and materials removed from the raw water. This ... -
In vitro polyploidization of selected indigenous plant species.
(2005)Many plant species indigenous to South Africa have ornamental, medicinal and horticultural value. Polyploidization is one technique that has been used to artificially produce superior genotypes, particularly in horticultural ... -
The potential for groundwater contamination arising from a lead/zinc mine tailings impoundment.
(2006)The mining industry produces vast quantities of overburden and mill tailings. In many instances the disposal of these wastes on the Earth's surface have caused local, and occasionally even regional, water resources to ... -
Phosphorous dynamics in soils under contrasting long-term agricultural management practices in the KwaZulu-Natal midlands.
(2006)Little is known regarding the effects of land use on soil organic matter and P status of South African soils. For that reason, the effects of the main agricultural land uses in the midlands region of KwaZulu-Natal [maize ... -
A comparison of soil and foliar-applied silicon on nutrient availability and plant growth and soil-applied silicon on phosphorus availability.
(2006)A greenhouse study was carried out to investigate the effectiveness of soil-applied silicon (Si) with that of foliar applications for sorghum growth. Silicon sources were soil-applied as calmasil (calcium silicate) at ... -
A comparison of soil extraction methods for predicting the silicon requirements for sugarcane.
(2007)Although silicon (Si) has not yet been recognized as an essential nutrient element, its application to sugarcane (Saccharum officinarum L.) has proved to be beneficial. Since optimum crop production depends on the maintenance ... -
A laboratory and glasshouse investigation on the effect of liming with fly ash and processed stainless steel slag on two contrasting South African soils.
(2008)Soil acidity is a major land degradation problem that limits crop production globally. The high cost of traditional liming materials (calcitic limestone, dolomite etc.) and the vast areas of land that require liming have ... -
Phosphorus sorption behaviour of some South African water treatment residues.
(2009)Water treatment residues (WTRs), which are by-products from the production of potable water, are chemically benign, inorganic materials which are suitable for disposal by land application. Their high phosphorus (P) sorption ... -
The influence of soil properties on the vegetation dynamics of Hluhluwe iMfolozi Park, KwaZulu-Natal.
(2009)The physical and chemical properties of soils can greatly influence the vegetation patterns in a landscape. This is especially so through the effect that particular characteristics of soils have on the water balance and ... -
A comparison of the effects of tillage on soil physical properties and microbial acitivity at different levels of nitrogen fertilizer at Gourton Farm, Loskop, KwaZulu-Natal.
(2010)Long-term food security and environmental quality are closely linked to maintaining soil quality. Therefore, the assessment of the effect of agricultural management practices on soil chemical, physical and biological ... -
A comparative study of the BCR sequential and batch extractions for wastes and waste-amended soil.
(2010)The use of standard soil tests to assess waste materials has become a common practice in waste management. However, the suitability of using standard soil tests on waste materials is questionable. Therefore, this investigation ...
