I am reviving this post as I just recently ran across the https://johnkempf.com/how-to-reduce-herbicide-application-rates/ blog post. I have the RO water set up and now want to get the fulvic ordered and on hand. I have read that 1 part fulvic to 5 part herbicide is the appropriate amount – so for roundup that comes out to about 2.5 ounces per acre – that doesn’t seem to be enough to me. I am also struggling to find much more guidance. Also would greatly appreciate some direction on what fulvic product to use and more importantly where I can get a quality product in the US? Thanks in advance!
