Science and Environment and Sustainability

Agricultural science is not just for the lab. Experts known as agronomists must head into the fields to see how their theories and studies play out in real life.

scientists tested threemain types of nitrogen fertilizers: synthetic, or man-made, fertilizers; animal manure; and crops like lentils and soybeans that can harness nitrogen directly from the air. The study showed that nitrogen is essential for old plant matter to break down completely into soil. In this the manure-based fertilizers were most effective.
