Nitrogen fertilizer costs are going up, and will continue to rise. Dr. Judy Grossman of North Carolina State University is concerned about the impact that will have on our future, so she's doing the research now to help us better understand how legumes and microbes work together to fix nitrogen in the soil. Her goal is to be able to give information to farmers that they can use to calculate how much nitrogen is being added to fields and pastures. Spend 2 minutes and 30 seconds with her to learn about how your future might be improved by the work she's doing. You tablet readers can click here to see the video.
