| Description: |
Microbiologists are discovering the potential of naturally-occurring bacteria called rhizobia to stem the tide of oversaturation with nitrogen-based fertilizers. If they can find better ways of getting nitrogen to plants, then they can improve the environmental impact of farming. They want to improve this process so we don't have to add as much fertilizer to fields. With active rhizobia, we can have productive crops while still protecting the environment and keeping our waterways safer. [Source: EurekaAlert!]
