Nutrient management is the science of optimizing the use of nutrients, such as fertilizers, in agricultural production in order to maximize crop yield and quality while minimizing environmental impact. This research area focuses on understanding the role of different nutrients in plant growth, determining the most effective ways to apply nutrients to crops, and developing sustainable practices to ensure long-term soil and water health. Nutrient management aims to strike a balance between providing plants with the necessary nutrients for growth and minimizing excess nutrients that can contribute to pollution and harm ecosystems.
