Book Description
Volume 72 contains four outstanding reviews detailing advances in the plant and environmental soil sciences. Chapter 1 deals with a timely and significant topic in North America and indeed in the world. This review provides background information, data sources and analyses, and implications for research and policy. Chapter 2 is a treatise on cutting-edge developments in bioremediation of petroleum-contaminated soils. Chapter 3 deals with the genetics of flowering time in the chickpea and its effect on productivity in semi-arid environments. Chapter 4 covers environment-sensitive genetic male sterility (EGMS) in crops.
Principles of Sustainable Soil Management in Agroecosystems
Author: Rattan LalPublisher: CRC Press
ISBN: 1466513462
Category : Nature
Languages : en
Pages : 571
Book Description
With the use of high-level soil management technology, Africa could feed several billion people, yet food production has generally stagnated since the 1960s. No matter how powerful the seed technology, the seedling emerging from it can flourish only in a healthy soil. Accordingly, crop yields in Africa, South Asia, and the Caribbean could be doubled or tripled through adoption of technologies based on laws of sustainable soil management. Principles of Sustainable Soil Management in Agroecosystems describes the application of these laws to enhance ecosystem services while restoring degraded soils and promoting sustainable use. With chapters contributed by world-class soil scientists, ecologists, and social scientists, this book outlines critical changes in management of agricultural soils necessary to achieve food security and meet the food demands of the present and projected future population. These changes include conversion to no-till and conservation agriculture; adoption of strategies of integrated nutrient management, water harvesting, and use of drip sub-irrigation; complex cropping/farming systems such as cover cropping and agroforestry; and use of nano-enhanced fertilizers. The book is based on the premise that it is not possible to extract more from a soil than what is put into it without degrading its quality. The strategy is to replace what is removed, respond wisely to what is changed, and be pro-active to what may happen because of natural and anthropogenic perturbations. The chapters, which exemplify these ideas, cover a range of topics including organic farming, soil fertility, crop-symbiotic soil microbiota, human-driven soil degradation, soil degradation and restoration, carbon sink capacity of soils, soil renewal and sustainability, and the marginality principle.

Management of Carbon Sequestration in Soil
Author: Rattan LalPublisher: CRC Press
ISBN: 1351091158
Category : Science
Languages : en
Pages : 843
Book Description
This book addresses the importance of soil processes in the global carbon cycle.Agricultural activities considered responsible for an increase in CO2 levels in our atmosphere include: deforestation, biomass burning, tillage and intensive cultivation, and drainage of wetlands.However, agriculture can also be a solution to the problem in which carbon can be removed from the atmosphere and permanently sequestered into the soil. Management of Carbon Sequestration in Soil highlights the importance of world soils as a sink for atmospheric carbon and discusses the impact of tillage, conservation reserve programs (CRP), management of grasslands and woodlands, and other soil and crop management and land use practices that lead to carbon sequestration.
The Economics of Agri-Environmental Policy, Volume II
Author: Richard D. HoranPublisher: Routledge
ISBN: 1351146955
Category : Business & Economics
Languages : en
Pages : 430
Book Description
This two-volume set collects key essays examining economic theory, methods, and issues salient to agri-environmental policy in the US and in Europe, as well as in other countries. The topics under discussion are arranged thematically and include theoretical, numerical and empirical works; all are grounded in policy and economics. The introduction to these volumes reviews the evolution of agri-environmental policies, with an important focus on the history of US policy and European agri-environmental policy. A key feature within this is the importance of the Environmental Protection Agency (EPA) in the US, particularly its move towards more 'market-based incentives' from the 1980s onwards. Within the European context, the effects of the CAP (Common Agricultural Policy) on agri-environmental programmes and schemes within the member states, are discussed. Significantly, the essays republished here have provided the knowledge base that has influenced further applied work, creating an influential impact on policy development.
