Soils of South Africa


Book Description

Soils of South Africa is the first book in seventy years that provides a comprehensive account of South African soils. The book arranges more than seventy soil forms into fourteen groups and then provides, for each group: • maps showing their distribution and abundance throughout South Africa • descriptions of morphological, chemical and physical properties • a detailed account of classification and its correlation with international systems • a discussion of soil genesis which includes a review of relevant research papers • appraisal of soil quality from a land use perspective as well as for its ecological significance • illustrative examples of soil profiles with analytical data and accompanying interpretations. There is also a fascinating account of the special relationship that exists between South African animals and soil environments. Soils of South Africa should interest students and researchers in the earth, environmental and biological sciences, as well as environmental practitioners, farmers, foresters and civil engineers.

Understanding Vineyard Soils


Book Description

The first edition of Understanding Vineyard Soils has been praised for its comprehensive coverage of soil topics relevant to viticulture. However, the industry is dynamic--new developments are occurring, especially with respect to measuring soil variability, managing soil water, possible effects of climate change, rootstock breeding and selection, monitoring sustainability, and improving grape quality and the "typicity" of wines. All this is embodied in an increased focus on the terroir or "sense of place" of vineyard sites, with greater emphasis being placed on wine quality relative to quantity in an increasingly competitive world market. The promotion of organic and biodynamic practices has raised a general awareness of "soil health", which is often associated with a soil's biology, but which to be properly assessed must be focused on a soil's physical, chemical, and biological properties. This edition of White's influential book presents the latest updates on these and other developments in soil management in vineyards. With a minimum of scientific jargon, Understanding Vineyard Soils explains the interaction between soils on a variety of parent materials around the world and grapevine growth and wine typicity. The essential chemical and physical processes involving nutrients, water, oxygen and carbon dioxide, moderated by the activities of soil organisms, are discussed. Methods are proposed for alleviating adverse conditions such as soil acidity, sodicity, compaction, poor drainage, and salinity. The pros and cons of organic viticulture are debated, as are the possible effects of climate change. The author explains how sustainable wine production requires winegrowers to take care of the soil and minimize their impact on the environment. This book is a practical guide for winegrowers and the lay reader who is seeking general information about soils, but who may also wish to pursue in more depth the influence of different soil types on vine performance and wine character.




The Soils of Spain


Book Description

This book provides the reader with a comprehensive overview of the soils of Spain gathered by a variety of Spanish experts in the field. It presents soils in this country as particularly conditioned by the naturally diverse and drastic distribution of the Spanish landscape, characterized by mountainous ranges in the North, and arid areas in the South and the East. The first chapter sets the agricultural scenario in Spain as influenced by the Arabic culture and American agricultural products; the second chapter provides a classification and distribution of Spanish soils; the third chapter approaches the topic of soils in the characteristically humid Northern Iberia area as prone to diversity and soil evolution; the fourth focuses on the soils of the South and East of Spain as affected by lack of rainfall and abundance in calcic soil horizons; the fifth chapter deals with Mediterranean soils, having as a particular characteristic the dominance of red colors; and the last chapter discusses the challenges and future issues of Spanish soils.




Transforming Agriculture in Southern Africa


Book Description

This book provides a synthesis of the key issues and challenges facing agriculture and food production in Southern Africa. Southern Africa is facing numerous challenges from diverse issues such as agricultural transformations, growing populations, urbanization and climate change. These challenges place great pressure on food security, agriculture, water availability and other natural resources, as well as impacting biodiversity. Drawing on case studies from Lesotho, Malawi, Mozambique, Namibia, South Africa, Swaziland, Tanzania, Zambia and Zimbabwe, the chapters in this book consider these challenges from an interdisciplinary perspective, covering key areas in constraints to production, the most important building blocks of good farming practices, and established and emerging technologies. This book will be a valuable support for informing new policies and processes aimed at improving food production and security and developing sustainable agriculture in Southern Africa. This informative volume will be key reading for those interested in agricultural science, African studies, rural studies, development studies and sustainability. It will also be a valuable resource for policymakers, governmental and nongovernmental organizations, and agricultural practitioners.

Soil Classification


Book Description

Developments in soil classification have accompanied parallel progress in our understanding of the soil system. However the theories behind the classifications and the purposes for which they were created have changed over time. The editors hope that this comprehensive synthesis will help to rally soil scientists around the world to develop an acce




Imperial Gullies


Book Description

Once the grain basket for South Africa, much of Lesotho has become a scarred and treeless wasteland. The nation's spectacular gullying has concerned environmentalists and conservationists for more than half a century, In Imperial Gullies: Soil Erosion and Conservation in Lesotho, Kate B. Showers documents the truth behind this devastation. Showers reconstructs the history of the landscape, beginning with a history of the soil. She concludes that Lesotho's distinctive erosion chasms, called dongas, often cited as an example of destructive land-use practices by African farmers, actually were caused by colonial and postcolonial practices. The residents of Lesotho emerge as victims of a failed technology. Their efforts to mitigate or resist implementation of destructive soil conservation engineering works were thwarted, and they were blamed for the consequences of policies promoted by international soil conservationists since the 1930s. Imperial Gullies calls for an observational, experimental and, most importantly, a fully consultative and participatory approach to address Lesotho's serious contemporary problems of soil erosion. The first book to bring to center stage the historical practice of colonial soil science and a cautionary tale of western science in unfamiliar terrain it will interest a broad, interdisciplinary audience in African and environmental studies, social sciences, and history. "Showers shows how local people understood that colonial contour conservation methods and road building actually stimulated gully erosion, something colonial scientists failed to realize. Overall it is undoubtedly one of the most important books written to date on any part of the environmental history of Africa. Moreover it stands out in the discipline of environmental history in general as an unusually sophisticated work of great insight and explanatory power."---Richard H. Grove, author of Green Imperialism: Colonial Expansion, Tropical Island Edens and the Origins of Environmentalism, 1600-1860 Kate B. Showers is a visiting research fellow and senior research associate at the Centre for World Environmental History, University of Sussex, England. She has lived in rural Lesotho and has served as head of research, Institute of Southern African Studies, National University of Lesotho.
