Agronomy is a science that looks at agriculture from an integrated, holistic perspective, informing practical decisions pertaining to food and fiber production. Agronomy requires integration of many sciences, and collaborations among many diverse fields, including soil, plant, and weed sciences, as well as the disciplines such as ecology, entomology, climatology, and economics. Effective crop production methods are grounded in scientific research and thus are by nature continually evolving and improving.
