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 ... -

(Academy of Science of South Africa, 2018)No abstract available. -
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.). ... -
Response of soil chemical properties to irrigation with winery wastewater on a well-drained sandy soil
(South African Society for Enology and Viticulture, 2019)Most wineries in South Africa dispose of their wastewater through land application. This is carried out by irrigating small areas of cultivated pasture with the wastewater or ponding, with the former being the more general ... -
Design of a pot experiment to study the effect of irrigation with diluted winery wastewater on four differently textured soils
(South African Water Research Commission, 2016-01)Due to the intensification of environmental legislation, the wine industry is expected to find solutions for the treatment or re-use of winery wastewater. The objective of the study was to design and evaluate a pot experiment ... -
Prescribing innovation within a large-scale restoration programme in degraded subtropical thicket in South Africa
(MDPI, 2015)Commonly cited requirements for bridging the “science‑practice divide” between practitioners and scientists include: political support, communication and experimentation. The Subtropical Thicket Restoration Programme was ... -
Soil moisture conservation in dryland viticulture as affected by conventional and minimum tillage practices
(South African Society for Enology and Viticulture, 1980)The effect of conventional clean cultivation, a straw mulch, chemical weed control and a grass sward on the soil moisture regime in a dryland vineyard was investigated. The results demonstrate that both a straw mulch and ... -
The effect of conventional and minimum tillage practices on some soil properties in a dryland vineyard
(South African Society for Enology and Viticulture, 1980)Preliminary results of a long-term viticultural tillage experiment comprising two groups of treatments, are reported. These groups are (i) a group of "minimum" tillage practices having received no mechanical soil tillage ... -
The effect of various supplementary irrigation treatments on plant and soil moisture relationships in a vineyard (vitis vinif era var. chenin blanc)
(South African Society for Enology and Viticulture, 1981)In a field plot trial with grape vines planted on a high potential soil, the soil moisture status on different irrigation treatment plots was compared with that of a dryland control. Soil moisture budgeting was based on ... -
The possible cause of red leaf disease and its effect on barlinka table grapes
(South African Society for Enology and Viticulture, 1993)The so-called red leaf (RL) phenomenon of Barlinka table grapes was investigated in the Hex River Valley, De Doorns. The symptoms of RL were found to resemble those of grapevine leafroll (GLR) disease to a certain extent, ... -
Nitrogen mineralisation in vineyard soils of the Western Cape as affected by soil management practices
(South African Society for Enology and Viticulture, 1995)Soil management practices like ridging, liming and irrigation are expected to affect the ability of microorganisms to mineralise plant residues in the soil through their effects on water regime, temperature, pH, organic C ... -
The effect of fertilisation on the performance of Barlinka table grapes on sandy soil, Hex River Valley
(South African Society for Enology and Viticulture, 1995)The response of Barlinka table grapes on grayish, sandy soil to irrigation-applied N fertilisation levels, patterns of N application, crop load and stock P and K fertilisation, were evaluated over a 12-year period in the ... -
The effect of irrigation system and crop load on the vigour of Barlinka table grapes on a sandy soil, Hex River Valley
(South African Society for Enology and Viticulture, 1995)The effect of drip and micro-sprinkler irrigation, as well as crop load, on the vigour of Barlinka table grapes was studied in a field trial in the Hex River Valley over a 12-year period. Regulating soil water by means of ... -
An assessment of winery wastewater diluted for irrigation of grapevines in the Breede River Valley with respect to water quality and nutrient load
(South African Society for Enology and Viticulture, 2015)Possible 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 ... -
Effect of irrigation using diluted winery wastewater on vitis vinifera l. cv. cabernet sauvignon in a sandy alluvial soil in the Breede River Valley – vegetative growth, yield and wine quality
(South African Society for Enology and Viticulture, 2016-09)The re-use of winery wastewater for irrigation was investigated in a field trial with micro-sprinklerirrigated Cabernet Sauvignon/99Richter in the Breede River Valley region of South Africa. Irrigation with winery ... -
Spatial soil information in South Africa : situational analysis, limitations and challenges
(Academy of Science of South Africa, 2015)Soil information is vital for a range of purposes; however, soils vary greatly over short distances, making accurate soil data difficult to obtain. Soil surveys were first carried out in the 1920s, and the first national ... -
Effect of irrigation with diluted winery wastewater on phosphorus in four differently textured soils
(South African Society for Enology and Viticulture, 2016-04)The wine industry needs solutions for wastewater treatment, as environmental legislation for its disposal is increasingly being enforced due to non-compliance. The feasibility of re-using diluted winery wastewater was ... -
Seasonal variation in composition of winery wastewater in the Breede River Valley with respect to classical water quality parameters
(South African Society for Enology and Viticulture, 2016-10)The annual wastewater quality dynamics of a winery from which wastewater was sourced for a field experiment investigating the dilution of winery wastewater for vineyard irrigation were determined. Annual mean monthly pH ... -
Quantifying the catchment salt balance : an important component of salinity assessments
(Academy of Science of South Africa, 2015)Soil and stream salinisation is a major environmental problem because it reduces the productivity of landscapes and degrades water quality. The Berg River (South Africa) has been exhibiting a trend of increasing salinity ...
