This year I am going to start spraying my first app. of fert. instead of using granular. I know there is a lot of personal opinions on this but-im gunnna do it. I am only spraying 1.5 gal/1000sq.ft. Has anyone had any problems using such a small amount of carrier for liquid fert? Urea is what I will be squirting. UFLEXX something around 80-90 #'s an acre melted. All Bermuda grass.
