This updated and expanded second edition textbook, describes all main aspects of soil management, to address the serious problems of soil erosion and the attendant environmental pollution. The global high demands for food, fiber, feed, and fuel put a constant strain on the environment, which can only be mitigated by soil conservation.This edition incorporates new concepts and provides an up-to-date review of soil management principles and practices. The authors also added new chapters on cover crops, crop residues, soil water management, nutrient management, perennials in crop rotations and organic amendments. All practices have a clear perspective on addressing soil erosion, physical and chemical problems, carbon dynamics and sequestration as well as non-point source pollution. The restorative nature of many practices, also consider water conservation as a main pillar of sustaining a healthy soil.This textbook is valuable for students and professionals in soil science, agronomy, agricultural engineering, hydrology, and management of natural resources.

Cover Crops and Soil Ecosystem ServicesA comprehensive resource on cover crops and their role in soil ecosystemsCover crops are a reemerging strategy to improve and maintain the services that soils provide. They can have an enormous affect on agricultural outcomes, preventing soil erosion, restoring vital soil nutrients, sequestering C from the atmosphere, and more. The successful management and use of cover crops is therefore critical to ensure soil ecosystem services are maintained or improved not only to meet our demands for food, fuel, fiber, and feed but also to reduce pollution and improve the soil.Cover Crops and Soil Ecosystem Services provides a heavily researched and highly readable introduction to cover crops and their role in soil ecosystems. It ranges from a detailed discussion of cover crop biomass production to a thorough treatment of soil ecosystems and their vulnerabilities. The result is an essential guide to a critical area of agricultural science.Cover Crops and Soil Ecosystem Services readers will also find:* Detailed treatment of cover crop biomass production, soil erosion, greenhouse gas fluxes, nitrate leaching, soil C sequestration, and more* Discussion of emerging issues, including extreme weather events and the economics of cover crop farming* Wide-ranging summaries of interdisciplinary soil and cover crop researchCover Crops and Soil Ecosystem Services is a useful reference for students and researchers at all levels of study relating to cover crop agriculture.
