Identifying, interpreting, and managing soil constraints are major challenges, especially when multiple constraints occur in the same soil at various depth zones. Although amelioration tools and strategies are available to manage some of these constraints, field adoption of these technologies is a major challenge to the farming community. Soil Constraints and Productivity helps in identifying and understanding soil constraints, focusing on management practices to alleviate problems associated with these restrictions, and their impacts on crop productivity. Soil Constraints and Productivity aims to: Describe various strategies suitable for mitigating soil constraints Provide data on cost-benefit analysis of managing soil constraints Provide case studies of managing soil constraints to increase productivity Soil is essential for the doubling of major grain production proposed to be necessary to avoid major food security collapses in the future. This book will be a key resource for soil and environmental scientists, farmers, students majoring in agricultural and environmental sciences, and crop consultants.

Globally, over two thirds of soils are affected by physical, chemical, or biological soil constraints. These constraints cause significant yield loss, and, as such, identifying appropriate management strategies is crucial to ensure future world food production. In order to help agricultural researchers and practitioners better understand soil constraint management, this book comprehensively outlines the occurrence of the major soil constraints and the most appropriate strategies to manage these for sustainable food production. Importantly, it brings together experts from major agricultural regions globally to highlight approaches with the most success in different environmental and socioeconomic regions worldwide.

Precision farming involves soil fertility and crop growth monitoring, electronic equipment, remote sensing, global information and positioning systems, computer models, decision support systems, variable-rate technology, and accurate recordkeeping. This book on precision techniques provides valuable information on instrumentation and methodology. I

This book--the first to apply the combined approaches of anthropology, geography, ecology, economics, and sociology to the analysis of the Amazon River region and its imminent development--explores the impact of development on Amazonian populations and the results of rural and urban growth strategies. The authors use the methodologies of environmen

Abstract: Food, water and energy form some of the basic elements of sustainability considerations. This ground-breaking book examines and decodes these elements, exploring how a range of countries make decisions regarding their energy and bio-resource consumption and procurement. The authors consider how these choices impact not only the societies and environments of those countries, but the world in general. 1. Sustainability - Clues for Positive Societal and Ecosystem Change2. Learning From the Past: Why Societies Collapsed or Survived3. Today: Decoding Country Resource Stories4.

Climate and Soils: Unavoidable Constraints To Solar CapitalPART 5. Societies Adapt To a Quagmire of Resource ChoicesReferencesTo achieve this, the authors review the merits of various sustainability and environmental metrics, and then apply these to 34 countries that are ranked low, medium or high on the human development index. The book assesses their resource capacities and the environmental impacts, both within and outside their country boundaries, from consuming food, water, and energy. The final section uses the lessons derived from the earlier analyses of resource consumption to explore the importance of geography, climates and sustainable management of forests and other natural resources for building resilient societies in the future
