Fulvic acid is not named for it's PH, but for other qualities. The fulvic acid molecule has both a positive and negative electron in the outer shell allowing it to either accept or give up an electron. That makes it an excellent antioxidant. It has two main purposes in nature, it binds non beneficial elements so they are not available for plant uptake, and it makes beneficial nutrients soluble for ready plant uptake.

Fulvic acid is produced by microbes in the soil, but as we have over applied chemical fertilizers, pesticides, herbicides and fungicides, we have reduced the microbes' ability to replicate. Low levels of microbes reduces available nutrients for plants to uptake resulting in less than healthy plants and produce.

GroTerra™ is sourced from CDFA certified organic spent mushroom compost. It is extracted using no chemicals, so the nutrients are water soluble and immediately available to plants when applied as a foliar spray, or applied to soil to improve the environment for microbial replication in order to heal soil.

GroTerra™ also has naturally occurring Humic acid, another humate with soil amendment properties.
