has anyone ever sprayed soluble urea with a permagreen, or tried to? i would be satisfied with a low rate like 10lb per 2gal (16,000 sqrft.) thats pretty concentrated, so im asking if it would burn, or simply not dissolve. i have a synergy sprayer, made by permagreen, sprays 2 gal per 16,000 sqrft im wondering about the 46-0-0 "sprayable" urea from lesco, or wherever. i know urea is very soluble, i just dont know how much. boy would it be nice not to have to carry so much granular. my gran is 75% ppscu so 1/2 or 1/4 rate of instant release liquid is fine for a small spurt to go with herbicide spraying.
