Colby, Kansas | I was a young, young pup the last time we used Anhy, so long ago that it was being put on with a tri-flex (an implement with three 5' sweeps for those not familiar).
Frame of Reference: Were in 80 bu corn country so the concentration impact of anhy vs. liquid or dry isn't a huge deal for us a given volume goes a lot farther for us than someone in the cornbelt. On irrigated ground fertigation is the way to go in terms of efficiency, timing, and eliminating involving a field operation. All of our N is applied at planting as 32% surface dribble approx 2.5 in from the seed slot.
Why we don't use Anhy (on the family farm)
1. Logistics: Many of the country elevator locations have quit their storage and nurse tanks, from our furthers field to NH3 supplier could be 30+ miles. We are spread out about 20 miles from furtherest point to furtherest point (which is fairly tightly grouped compared to our larger neighbors). The miles and labor it would take to pull tanks around and the associated liability of going up and down the road make it prohibitive. Even if we built our own bulk storage, it would still be an issue.
2. Safety:
3. No-Till: We've been no-till corn and sorghum since the late 70's and completely no-till since the mid 90's, not convienced there is a real good way to get anhy on in a no-till situation.
4. Convenience of liquid, its just easier to store, transport, and handle.
Why we don't use Anhy (on the experiment station)
1. Safety
2. Almost impossible to accurately meter at the plot scale
3. Convenience of liquid and dry

Why do you choose to or not to use anhydrous?
