I would questions the use of humates based on what you have written above.
If someone wants you to use them or suggests you use humates I would ask why
and what info they have to supports such a recommendation. When I was at
Rodale we developed a pub on alternative ag products and I remember that
humates are not all the same and some seemed to tie up soil P. If you could
provide more soil test info it would be helpful.
I am suspicious of solving all or most farming problems with something out

do the job as well as just good farming practices such as good soil organic
