Fulvic acid is a bi-product of humic acid. Humic acid is extracted from any material containing well-decomposed organic matter. As humic material is decomposed by living microbes, these microbes create fulvic acid.
Humic and fulvic acids are intermediate chelators. "Chela" means claw, so chelates are organic molecules that attach to mineral ions like a claw, holding them tightly enough so they don't get locked up in the soil, but loosely enough so they are available to the plant on demand.
Fulvic acid is humic material that is light yellow to yellow-brown in color but it is soluble at all pH levels.
Ful-Proof is ideal for use on all soils and plants under all conditions. Fulvic acid may be administered via foliar applications. It has a very low molecular weight which facilitates penetration into plants. Because of this characteristic of fulvic acid, it is very efficient when applied as root drench or foliar spray. Nutrients can be quickly delivered to all sites within the plant, correcting deficiencies and restoring natural balance. This same ability to penetrate plants can be a useful aid with defoliant and contact herbicides.
