Comparative characteristics of biochar types from human faecal wastes and pine-bark and sorption of selected heavy metals from effluent and their mobility in an amended loam soil.
(2018)Heavy metals from industrial effluents poses risks to the environment and human health. Pyrolysis of locally available organic wastes could address solid organic waste management and produce a biochar that could immobilise ... -
Application of soil indigenous knowledge in rural communities of eastern South Africa.
(2018)This study investigated ethnopedological knowledge related to classification, fertility and non-agricultural uses of soil in four villages in KwaZulu-Natal and the Eastern Cape, South Africa. Ethnographic methods elicited ... -

Evaluation of extraction based fertilizer recommendations.
(2015)There is a need to improve methods by which nitrogen, phosphorus and potassium are currently recommended. There is a considerable lack of mechanistical justifications for the methods used to recommend these nutrients. Lack ... -
Grassland degradation and rehabilitation of soil organic carbon and nitrogen stocks.
(2014)Land degradation is widely considered to adversely affect soil fertility, soil quality, constrain productivity, subsequently leading to a decline in soil organic carbon (SOC) and nutrients in soils, yet little is known ... -
Characteristics of sesquioxidic soils.
(1974)Sesquioxidic soil clays from Oxisols in South Africa, Australia and Brazil, and two clays from Andosols in Japan and New Zealand, were investigated by XRD, OTA, IR, EM and quantitative mineralogical analysis. The ... -
Soil acidity and liming in Natal.
(1970)1. Effects of Aluminium Toxicity and Phosphorus Fixation on Crop Growth on Oxisols in Natal Simple, routine methods for estimating exchangeable Al and P fixing capacity of acid soils are described. A glass-house study ... -
Factors affecting nitrogen utilization by sugarcane in South Africa.
(1972)TIhe response of sugarcane to applied N in South Africa varies considerably from one soil to another, particularly in the plant crop. Responses to fertilizer N by ratoon cane are generally much greater than those given ... -
Soil physical factors affecting root growth and maize yield in four Rhodesian soils.
(1976)The platinum microelectrode technique for measuring oxygen flux in soils has been reviewed. Shortcomings in the existing technique and instrumentation have been discussed. The new instrumentation, electrode standardization ... -
Occurrence and properties of iron and titanium oxides in soils along the eastern seaboard of South Africa.
(1978)Abstract available on PDF file. -
Estimation of hydrological properties of South African soils.
(1983)A computer simulation model of the soil water regime can be a useful research, planning and management tool, providing that the data required by the model are available. Finite difference solutions of the general flow ...
