SOIL PREPARATION FOR SUSTAINABLE WINE AND TABLE GRAPE VINEYARDS
The book covers knowledge gleaned from research and practical experience that accumulated in South Africa over the past 100 years. Soil preparation, often regarded as deep tillage only, also includes many other forms of soil profile modifications such as ridging, drainage, terracing, reclamation of saline soils and even planting holes. Soil type predominantly determines what soil preparation practices and implements are required. The book aims to give practical information on these topics, but also to explain the background to such recommendations and to provide experiment evidence in support. Throughout the book, the aim of soil profile modification takes into account root distribution, which is a prerequisite for maximised and sustainable grapevine performance. The target readership is growers, students, technical advisors as well as researchers who wish to delve further into the subject in order to continue to work in this field.
FERTILISATION GUIDELINES FOR THE TABLE GRAPE INDUSTRY
In 1994, Conradie published a manual providing guidelines for grapevine fertilisation. This manual provided a solid basis for industry over the years, but after 20 years new local and international information has become available and must be made available. So, the need to review the existing guidelines and to update it by incorporating new research results or perspectives came about.
BEMESTINGSRIGLYNE VIR DIE TAFERDRUIFBEDRYF
In 1994 het Conradie ‘n bemestingsriglyne-handleiding vir wingerd gepubliseer. Dié handleiding bied ‘n stewige basis vir die dedryf maar na 20 jaar is dit so dat nuwe inligting oor bemesting van wingerd hetsy nasionaal of internasionaal beskikbaar raak. Die behoefte het gevolglik ontstaan dat die wingerdbemestingshandleiding van 1994 hersien moet word sodat nuwe navorsingsresultate wat verskyn of sienings water verander het binne die handleiding geïnkorporeer kan word.
