Several chapters emphasize ecology and the environment: conservation tillage with emphasis on ecological approaches to soil management, especially its effects on the environment, soil physical and chemical properties, and surface mulch, nutrient, and pest management; a complete and contemporary review on integrated pest management, ecological and environmental considerations, and future directions; a comprehensive review of cadmium accumulation in plants and its effects on human health.
