Soils in Our Environment contains the most current information available and addresses perplexing issues and problems associated with preserving our soils.

Based on the most current scientific developments in all areas, this time-honored, broad introduction to soil sciences covers the complete spectrum of traditional and state-of-the-art soil topics—e.g., taxonomy, soil formation, properties of soils, common soil problems and their solutions, evaluation of soils, pollution from use of soils, precision agriculture, GIS, and GPS, wetlands, and use issues.

New to this Edition:

• Updated with recent advances in science, policy, and practices—e.g., global dust movements, tillage erosion, the phosphorus index, organic farming, P index, manure management, specific remedies for soil problems, and other aspects of landscape features, soil chemistry and environmental remediation.
• Revised end-of-chapter questions
• More soil-related human-interest stories—e.g., the effects of green rooftops on urban environments and the soil connection to anthrax

Soils in Our Environment provides a complete foundation for anyone interested or involved in soil science.
