Antagonist? If that is your opinion then that is fine. As I recall I first responded to the OP with Q&A about the product.
I have been spraying liquid fert for over 20 years so when someone says one app of UAN keeps a lawn green all year catches my eye. I wanted to learn more how I could save money and do a better job but all I keep getting is a changing story on every response. I am always looking at new ideas and products that might help turf health.
There is a jerk in every crowd.
