Nitrogen pools: Our experts talk timing, testing and uptake

In this episode of the Advancing Nitrogen Smart series, our two experts discuss nitrogen pools. What are nitrogen pools, and where do we find them? How is N actually consumed by the plant, and what forms of N will plants take up more readily? What are some potential signs of N deficiency in the plant? How do nitrogen pools relate back to the 4R's, like timing?

Guests:

• Brad Carlson, Extension educator (Mankato)
• Daniel Kaiser, Extension nutrient management specialist (St. Paul)

Additional resources:

• Will soil microbes deliver nitrogen to my crop? Yes, but not in a predictable way
