Program Profile
Nitrogen — Plants cannot survive without nitrogen (N). Healthy plants contain up to 5% of this vital nutrient and the Earth’s atmosphere is about 78% N…it is all around us. There are approximately 75 million lb of N in the atmosphere above each acre. Huge amounts of N are also present in soils, water bodies, and fossil fuels. But although N is in abundant supply, it must be converted to a different form before plants can use it.
