Anyone with experience with humic acid?

I wanted to try humic this year either in furrow or out the back with UAN. I've had constant trouble from initial in furrow reacted with starter fertilizer zinc I think, then I tried jar test with UAN and it sludged up a little, finally just had humic and water and a biological and it seems like the humic gets trapped in a 50 mesh filter. After lots of headaches I just pulled the 50 mesh and then it ran fine, just wanting anyone's help to know rates/etc.? was going to run 1 gpa of 16 percent humic (FBN Nhabit build) with 15 gap of UAN out back, maybe my problem is literally my 50 mesh screen? I use orifice disks to regulate flow, so the initial zinc/humic settling I think would plug a disk, and now without any metals to react with I just don't even run a screen which is risky haha..

Take a look at Agzyme products for humic acid. I've used Agzyme for 8 years and Enhance gave me 16% yield increase.
