Agricultural Scientists get their hands dirty by studying plants and soil. The research they do helps to find new ways to grow the delicious fruits, vegetables, and grains that we eat everyday. They use the principles of biology, chemistry, and other fields to solve problems related to agriculture. If insects are ruining a crop or if the soil in a certain area isn’t fertile, an agricultural scientist can help. Federal and state governments, as well as farmers and food companies, employ these “green thumb” scientists.
