Integrated approach to nutrient cycling monitoring
(Academy of Science for South Africa, 2007)There are two issues of social importance in relation to nutrient cycling. The first is the depletion of nutrients in croplands and rangelands. The second is the overabundance of nutrients through the enhancement of inputs, ... -
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 ... -
Petroduric and "petrosepiolitic" horizons in soils of Namaqualand, South Africa
(Universia, 2012)Indurated, light-coloured 'sepiocrete' horizons have been found in Namaqualand Calcisols and Durisols. These horizons resembled calcrete but were non- to only mildly calcareous, resisted slaking in acid and alkali, and ... -
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, ... -
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 ... -
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 ... -
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 ... -
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.). ... -
The role of wild vegetable species in household food security in maize based subsistence cropping systems
(SpringerLink, 2013-02)Wild vegetables (WV) are an important source of food in the maize based subsistence farming sector of rural South Africa. Their main role is as relish as they are used as an accompaniment for staple cereal based diets. ... -
Searching for David within the Goliath of alien woody plant invasions in the Western Cape Province
(Academy of Science of South Africa, 2018)No abstract available. -
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 ... -
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 ... -
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 ... -
Survivorship of spekboom (Portulacaria afra) planted within the Subtropical Thicket Restoration Programme (with Corrigendum)
(Academy of Science of South Africa, 2017)No abstract available. -
Trace element composition of two wild vegetables in response to soil-applied micronutrients
(Academy of Science of South Africa, 2014)Wild vegetables are an important commodity in the subsistence farming sector. They are considered to be rich in micronutrients and can therefore be used to overcome inadequate nutrition. However, research on micronutrients ...
