Long regarded as the leading book in the field, this volume provides a basic introduction to the biological, chemical, and physical properties affecting soil fertility and plant nutrition. It covers all aspects of nutrient management for profitable crop production, with particular attention to minimizing the environmental impact of soil and fertilizer management. The Seventh Edition has been substantially revised to reflect rapidly advancing knowledge and technologies in both plant nutrition and nutrient management. Crop specific data to estimate nutrient status and needs for many diverse products are provided, as well as example calculations that are routinely used in the market make this a comprehensive resource tool. Nutrient management, water use, and economics are all fully covered. Comprehensive discussions of the development and use of nutrient recommendation systems make this an excellent reference and must-read for soil professionals, technical service providers, extension agents, and crop consultants.
