Like all living things, plants are composed mainly of carbon, hydrogen and oxygen. But without nitrogen (N), a plant ceases to be a plant and, in effect, life as we know it does not exist.

Nitrogen is a key ingredient in amino acids that make up proteins. It’s also a component of chlorophyll – the biomolecule plants use to absorb energy from sunlight through the process of photosynthesis. Nitrogen is a structural component of enzymes that enable genetic and metabolic reactions that stimulate cell division.

Nitrogen deficiency limits crop growth: less nitrogen = smaller leaves = less chlorophyll = less photosynthesis = lower yield and lower protein levels = less food for our world.
