A comparative study of the BCR sequential and batch extractions for wastes and waste-amended soil.
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 ...
A comparison of soil and foliar-applied silicon on nutrient availability and plant growth and soil-applied silicon on phosphorus availability.
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 ...
Phosphorous dynamics in soils under contrasting long-term agricultural management practices in the KwaZulu-Natal midlands.
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 extraction methods for predicting the silicon requirements for sugarcane.
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.
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 ...
The influence of soil properties on the vegetation dynamics of Hluhluwe iMfolozi Park, KwaZulu-Natal.
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 ...
