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.
