Using remote sensing and geographical information systems to classify local landforms using a pattern recognition approach for improved soil mapping
(Stellenbosch : Stellenbosch University, 2022-05)ENGLISH ABSTRACT: Presently, a major focus of digital soil mapping (DSM) in South Africa is unlocking the soil-landscape relationships of legacy soil data by disaggregating the only source of contiguous soil information ... -
Quantifying water movement in soils irrigated by continuous drip irrigation with citrus in the Western Cape
(Stellenbosch : Stellenbosch University, 2022-04)ENGLISH ABSTRACT: The development of low discharge rate emitters by Netafim opened new possibilities to approach irrigation and fertilization and introduced continuous low flow drip irrigation, allowing for intensive ... -
Structure and chemistry of two heuweltjies in areas with contrasting aridity in the Olifants/Doorn catchment: evidence for downward salt movement
(Stellenbosch : Stellenbosch University, 2022-04)ENGLISH ABSTRACT: The Olifants/Doorn catchment in the West Coast region of South Africa is variably affected by saline groundwater. Other areas along the coast of southern Africa experience similar mean annual precipitation ... -
The effects of long-term tillage and crop rotation practices on nutrient stratification in the Western Cape
(Stellenbosch : Stellenbosch University, 2022-04)ENGLISH ABSTRACT: The Western Cape is one of the most successful provinces in South Africa in converting to Conservation Agriculture (CA), with an adoption rate of around 80%. CA is a production system that promotes ... -
Conversion of soil pH values and exchangeable base cation quantities determined by different methods
(Stellenbosch : Stellenbosch University, 2021-12)ENGLISH ABSTRACT: Soil management recommendations based on chemical test results rely on comparisons with norm values developed using specific analytical methods and soil taxonomic classes. Conversions of soil pH and ... -
Evaluation of old store-and-release covers on discard dumps and backfilled pits to improve and predict their performance for rehabilitated mines at Mpumalanga Highveld, South Africa
(Stellenbosch : Stellenbosch University, 2021-12)ENGLISH ABSTRACT: Store-and-release covers (SRCs) are an important mitigation method to protect the environment at rehabilitated mines in the Mpumalanga Highveld, South Africa. The long-term performance of SRCs can be ... -
Effect of lime source, form and placement on soil pH neutralisation and permeation
(Stellenbosch : Stellenbosch University, 2021-03)ENGLISH ABSTRACT: Currently, agricultural producers in South Africa are uncertain about the relative effectiveness of locally available class A and granulated micro-fine lime sources, especially in terms of soil permeation and ... -
Quantifying a sponge : the additional water in restored thicket

Water treatment residual: potential amendment to a sandy soil
(Stellenbosch : Stellenbosch University, 2021-03)ENGLISH ABSTRACT: Water treatment residual (WTR) is a waste product generated during the water treatment process. This study assesses the potential of using WTR as a potential amendment or co- amendment ... -
The effects of selected soil physical properties on the soil water balance, soil water redistribution and pyrrolizidine alkaloids loads in two diferent textured soils in the nieuwoudtville rooibos tea production area
(Stellenbosch : Stellenbosch University, 2021-03)ENGLISH ABSTRACT: Rooibos (Aspalathus linearis) is an endemic crop of South Africa produced only in the south western parts of the country. This includes the Northern Cape where the production was reported to have declined ... -
Assessing the influence of DEM source on derived streamline and catchment boundary accuracy
(South African Water Research Commission, 2019)Accurate DEM-derived streamlines and catchment boundaries are essential for hydrological modelling. Due to the popularity of hydrological parameters derived mainly from free DEMs, it is essential to investigate the accuracy ... -
Assessing the potential of using microcomputerized tomography to determine the physical properties of different textured soils
(Stellenbosch : Stellenbosch University, 2020-12)ENGLISH ABSTRACT: The physical properties of soil, particularly the structure, texture, and pore geometry affect hydraulic conductivity in soils. The hydraulic conductivity is an important parameter for understanding the ... -
Effects of anabolic and catabolic nutrients on woody plant encroachment after long-term experimental fertilization in a South African savanna
(Public Library of Science, 2017-06-29)The causes of the worldwide problem of encroachment of woody plants into grassy vegetation are elusive. The effects of soil nutrients on competition between herbaceous and woody plants in various landscapes are particularly ... -
Effect of irrigation using diluted winery wastewater on the chemical status of a sandy alluvial soil, with particular reference to potassium and sodium
(South African Society for Enology and Viticulture, 2018)The re-use of winery wastewater for irrigation was investigated in a field trial with micro-sprinklerirrigated Cabernet Sauvignon/99 Richter in the Breede River Valley region of South Africa. Irrigation with winery ... -
The effect of domestic greywater on soil quality of urban soils from the Cape Town and Stellenbosch areas
(Stellenbosch : Stellenbosch University, 2020-03)ENGLISH ABSTRACT: During a recent drought and water scarcity in the Western Cape, the reuse of greywater for garden irrigation was encouraged. Greywater, although considered less polluted than same other wastewaters, can ... -
Survivorship of spekboom (Portulacaria afra) planted within the Subtropical Thicket Restoration Programme (with Corrigendum)
(Academy of Science of South Africa, 2017)No abstract available. -
Annual dynamics of winery wastewater volumes and quality and the impact of disposal on poorly drained duplex soils
(South African Society for Enology and Viticulture, 2018)The composition and volume of winery wastewater change throughout the year. Quality is usually at its worst when vintage operations are dominated by the production of red wines. The objective of this study was to investigate ... -

Restoration of wetlands on the Agulhas Plain is unlikely to generate peat
(Academy of Science of South Africa, 2018-02)Wetlands in the Nuwejaars Special Management Area (NSMA) on the Agulhas Plain of South Africa are classified as Western Cape Floodplain Wetlands1 and are characterised by dense stands of palmiet (Prionium serratum L.f.). ... -
Soil spectral characteristics and their predictive value in relation to spatial and temporal variability in wheat yield and soil quality within a long-term field trial
(Stellenbosch : Stellenbosch University, 2019-12)ENGLISH ABSTRACT: Soil is a heterogeneous growing medium, with complex processes and mechanisms that are not easy to be fully understood. Soil spatial variations may be encountered within short distances, and these variations, ...
