Water- en soutbalanse van geselekteerde besproeide gronde van die benede Bergrivier opvanggebied
(Stellenbosch : Stellenbosch University, 2004-04)
ENGLISH ABSTRACT: A study was conducted between 2000 and 2002 in the lower Berg River catchment of the semi-arid Western Cape Province to investigate the effect of irrigation developments (wheat fields to table grapes) ...
Experiments to modify grape juice potassium content and wine quality on granite derived soils near Paardenberg
(Stellenbosch : University of Stellenbosch, 2006-12)
High potassium content in grape juice and wine are associated with low quality red wine in warm wine producing countries. In an attempt to reduce the potassium content of juice, must and wine, a field experiment was laid ...
Die effek van verskillende oppervlakbewerkingspraktyke op die wortelverspreiding van wingerd
(Stellenbosch : University of Stellenbosch, 2007-03)
This study forms part of an ARC Nietvoorbij research project on the long-term effect of different groundcover management practices in vineyards. This study concentrated on the root distribution of the vines after different ...
An evaluation of the effectiveness of coal ash as an amendment for acid soils
(Stellenbosch : Stellenbosch University, 2008-12)
Soil acidity is one of the greatest limitations to crop production in most soils of the world. The increasing high costs of conventional liming materials have made it necessary to explore the possibilities of using cheaper ...
Soil Formation on the Namaqualand Coastal Plain
(Stellenbosch : University of Stellenbosch, 2008-03)
The (semi-)arid Namaqualand region on the west coast of South Africa is wellknown for its spring flower displays. Due to the aridity of the region, soils research has lagged behind that of the more agriculturally productive ...
Soil fertility constraints to small-scale agriculture in North-west Zambia
(Stellenbosch : Stellenbosch University, 2008-03)
The soils of north-west Zambia are largely unexplored and are regarded by local residents as problematic in providing sufficient nutrients for the staple crop of maize in the area. The area is semi-tropical, with an average ...
Geology, particle size distribution and clay fraction mineralogy of selected vineyard soils in South Africa and the possible relationship with grapevine performance
(Stellenbosch : Stellenbosch University, 2001-03)
ENGLISH ABSTRACT: This study is an integral part of a multidisciplinary research project concerning the effects of soil and climate on wine quality. The motive, which led to the setting up of this project, was that ...
Comparison of different methods by means of which water holding capacity of soil is determined and the prediction of water holding capacity from soil texture in coarse-textured soil
(Stellenbosch : Stellenbosch University, 2004-12)
ENGLISH ABSTRACT: Irrigation scheduling is one of the most important cultural practices in irrigated vineyards. Water holding capacity of soil is arguably therefore one of the most important characteristics of a soil as ...
Synthesis and characterisation of sesquioxidic precipitates formed by the reaction of acid mine drainage with fly ash leachate
(Stellenbosch : University of Stellenbosch, 2003-04)
ENGLISH ABSTRACT: Coal mining in South Africa is estimated to produce 200 Ml of acid mine drainage (AMD) per day in the Pretoria-Witwatersrand-Vereeniging (PWV) area alone, while electricity production resulted in ...
