I was curious, what do you base your N requirements on when you put melted urea on, do you do a sap test or just go with what you always have. Second, when you melt urea, how do you do it? I have seen different guys do it with cone bottom tanks and keep the pump cycling for a half hour. I was looking at putting together a setup for my farm. I am looking at applying some urea this way and liquid urea is unbelievably priced.
