Agronomy looks at agriculture from an integrated, holistic perspective. Agronomists are specialists in crop and soil science, as well as ecology. Some things they look at are:

  1. The properties of the soil;
  2. How the soil interacts with the growing crop;
  3. What nutrients (fertilizers) the crop needs;
  4. When and how to apply these nutrients;
  5. The ways that crops grow and develop;
  6. How climate and other environmental factors affect the crop at all stages;
  7. How best to control weeds, insects, fungi, and other crop pests; and,
  8. How to grow crops effectively and profitably while conserving and protecting the environment.
