| We will begin applying preplant herbicide later this week, and we still have at least 4 weeks to go when low temps can dip into the mid 20's or lower. I would like to avoid draining the pump, also we can't drain the SS boom plumbing. I thought that adding about 10% of 28% UAN with 90% water would lower the freezing point enough that we would not have to worry about the sprayer freezing. Does anyone have a chart or formula that shows how different concentrations of 28 UAN affect the freezing point of water? | |
