St. Charles, MO & Piper City, IL | You had the same formula/chart I did 15 years ago. Come to find out they varied it by tank test I found out after using it. I’ve seen UAN test as high as 33.5 off barges in the past. I caught this loading at GCT when they had driver take load ticket from scale to loader. They were adding water to 32% loads because it tested hot. |
