Soil Fertility and Plant Nutrition is an applied science that integrates knowledge across all disciplines of soil and plant sciences to effectively and efficiently provide nutrients to plants. Efficient use of nutrients is required not only to maximize agricultural production but also to protect air, soil, and water quality as well as the natural resources involved in providing fertilizers to support agricultural production.
