SOIL PREPARATION

The modification of the soil profile before planting to remove impediments to root growth and provide an improved available rooting volume adequate for optimum grapevine performance is generally known as soil preparation. Various investigations in South Africa have addressed soil compaction, chemical restrictions to root penetration, root distribution, soil ameliorants such as lime, implements, soil types and many other related aspects. This body of knowledge is not only spread over many years and different generations of researchers and experts, but is also fragmented among many articles and journals. In short, a divide has developed between available knowledge and the end-users of the knowledge. Considering the determining role of soil preparation in the successful establishing of a vineyard and the huge costs involved, it is imperative that all the available information is compiled correctly in one place, hence the need for writing this book. In order to make this knowledge source as comprehensive as possible, relevant international information was integrated with the South African work. This will enable everybody to apply the best soil preparation practices for vineyard soils and eliminate confusion/pseudo-expertise around this important subject. INTRODUCTION
