Using Humic Acid for Cannabis Production

Using Humic Acid for Cannabis Production Professor DeBacco What is Humic Acid? Humic and Fulvic acids are the final break-down components decaying plants and animals and found in pre-historic deposits. The one source of humic acids are the sedimentation layers referred to as Leonardite. Leonardite is organic matter, which has not reached the state of coal and differs from soft brown coal by its high oxidation degree, a result of the process of coal formation, and has no value as fuel.

Frontiers in plant science, 10, 736. https://www.frontiersin.org/articles/... Humic Acid and THC Levels For example, following HA application THC levels at the top of the plant was reduced from 11.8 to 7.4%, and consequently concentrations throughout the plant height did not differ significantly Humic Acids Impact The nutrition treatments were supplemented with HA, enhanced P fertilization, or enhanced NPK. HA was found to reduce the natural spatial variability of all of the cannabinoids studied. The results demonstrate sensitivity of cannabinoids metabolism to mineral nutrition. Nutrients Impact on Cannabinoids P enhancement treatment did not affect THC, CBD, CBN, and CBG concentrations in the flowers from the top of the plants, a 16% reduction of THC concentration was observed in the inflorescence leaves. NPK supplementation increased CBG levels in flowers by 71%, and lowered CBN levels in both flowers and inflorescence leaves by 38 and 36%, respectively.
