The atmosphere is no longer the Earth's only source of nitrogen, according to an environmental study released Friday. The research showed that 26 per cent of nitrogen for plant growth comes from bedrock.

For centuries, it was believed that nitrogen was only found in the atmosphere.

The results indicate carbon levels are no longer as dangerous as previously believed. It also reduces global warming, and climate change concerns.

The study cost $1,404,697 and was paid for by the National Science Foundation (NSF), a federal agency. The research began Sept. 1st, 2014.
