Salinity and Sodicity
Description
Explore the growing problem of soil salinity and sodicity and its impact on the environment, profitability, the human population, and soil resilience
In Salinity and Sodicity: A Global Challenge to Food Security, Environmental Quality, and Soil Resilience, a team of distinguished educators delivers an expert discussion of salinity and sodicity management. This book is designed to improve the problem-solving capabilities of students, soil health professionals, certified crop advisors, and other practicing professionals in this area.
In addition to an introduction to the causes of a rapidly growing problem, Salinity and Sodicity explores different measurement techniques, provides answers to common questions, provides potential solutions in a way that's appropriate for introductory classes on soil salinity and sodicity management. It's an ideal reference manual for professionals, as well as an effective tool for classrooms and crop advisor workshops.
Readers will also find:
- A thorough introduction to the use of supplemental irrigation and the impact of salts on the environment
- Comprehensive explorations of the economic considerations for farming problematic soils
- Practical discussions of the effects of salinity and sodicity on erosion and greenhouse gas emissions
- Practical case studies, problem sets, and an instructor answer key
Perfect for undergraduate, graduate, and doctoral students and certified and practicing soil professionals and advisors, Salinity and Sodicity will also benefit industry and academic researchers with an interest in soil salinity and sodicity in dryland regions.
