After my first year of using it, here are my thoughts.

Fall banding 100% of N needs for the next year worked great.  Yields on my flax are showing it.

Using it in a blend and seed applied in the spring time, not so great.  I did notice a bit of plant stand damage to the high rate of N put down with the seed.  Probably not a big concern in the end as our wheat yields are higher than most of our neighbors.

My winter wheat trial last fall, showed that I had the same yield as our top dressed fields, but it was lower in protein by .7%.

I am going to use it again for fall banding this year, but my fertilizer blend next year won't have as much ESN in the mix, and I will be having to top dress as well.
