Fulvic has its uses as a chelator for micro nutrition, and also some other chemicals. I have tested the Fulvic/Citric acid theory with glyphosate and it really does work. we got a faster and more complete kill using 2l of Azural plus Fulvic/Citric acid compared to farm standard 3l on OSR volunteers. Modest 50p/ha saving though. However, if the theory is sound, then potentially huge saving in N can be made by using foliar N products properly in order to get decent uptake.
