Humic substances have a high anion exchange capacity which allows them to hold nutrients such as nitrogen and phosphorus in the soil and prevent them from leaching. There are three different fractions of humic substances generally referred to as humic acid, fulvic acid, and humin.
In this webinar, John describes the roles of these three fractions, how manufactured humic acids and fulvic acids are produced, and where and how to use them for the greatest crop response. John also describes HumaCarb, AEA’s humic acid product, why it is more effective than other humic acids, and how to use it.

• Prevent nitrogen leaching
• Provide fungal food source
• Stabilize phosphorous
• Increase absorption of nutrients
• Tie up chemicals such as
cadmium and sodium
• Increase plant biomass
• Enhance root growth

Humic substances have
tremendous untapped potential
to positively impact biology
Using chemical extraction substantially reduces
the effectiveness of humic substances.
Many humic acid products are
chemically extracted which
denatures the components.
Naturally processed products deliver
greater performance and results.
AEA products are not chemically

comply with the USDA National Organic Program (NOP) rules for certified organic crop
production. Verify with your organic certiﬁer before using.
CONTAINS NONPLANT FOOD INGREDIENTS
Soil Amending Ingredients:
10% Humic acid (derived from humalite)
90% Total Other Ingredients
Purpose: HumaCarbTM is a soil conditioner and may aid in micronutrient uptake.
APPLICATION RATES AND TIMING Thisproductisintendedforsoilapplicationsandshouldonlybeusedin
accordancewith the manufacturer’s directions.
Side dress: Mix with liquid nitrogen fertilizer at 3% of solution.
Small Grains: Apply up to 2 quarts per acre at late tilling or as needed.
Vegetables and Fruits: Apply up to 1 quart per acre per week, starting at transplant or greening.
Handling: Store in a cool dry area out of direct sunlight. This product has been tested to store safely down to
35°F. Crystallization or sedimentation may occur below 35°F or above 95°F. Shake or stir before use to
dissolve any residue on the bottom of the container. Do not pre-mix or store in diluted form. Always use
product within 8 hours of diluting.
When tank mixing: A jar test is recommended: Prepare a small amount of the proposed mix and allow it to
stand in a glass jar overnight observing for signs of incompatibility. Ideally, a sample of the test mix should
then be sprayed on a small area of the target crop and observed for 3 to 4 days for any phytotoxic effects.
Agitation is the key to usability of this product. AEA products involve tiny particles which are far too small to
clog ﬁlters; however, if they are inadequately diluted or agitated before and during application there is a
possibility of problems with spray equipment. Consider using an eductor nozzle to agitate prior to use.
Compatibility and/or performance cannot be guaranteed when combined with other products.Density: 9.20 lbs. per gallon at 68oF

1. Depending on the form of fertilizer applied, nitrogen may become a structural component of humic substances as a stable organic material, preventing it from leaching
through the soil. (Haworth, 1971; Stevenson, 1982; Haynes and Swift, 1990; Kelly and Stevenson, 1996) In their natural state, humic substances contain anywhere from 1%
to 5% nitrogen. Reduction of nitrogen application (Day, et al, 2000, Fataltah, et al, 2001)

nutritional supplement makeup
HumaCarb™ is derived from a complete humalite ore
which contains the humic acid, fulvic acid, and humin
compounds found in these deposits.
Humic acids are usually extracted from leonardite
ore in a strong alkali solution generally using
sodium or potassium hydroxides. Compared to
leonardite products, humalite contains less ash, fewer
heavy metals and much more humic and fulvic acids.
Unlike other humic acids available on the market,
HumaCarb™ is produced using a process that
preserves all the natural properties of the humic

application rates and timing
Usual application rates are 2-3 quarts per acre.
HumaCarb™ should be tank mixed with liquid
fertilizers at a 3% solution.
