Humic Acid is the fraction of organic matter that contains very high active carbon and contributes to a soils cation exchange capacity (CEC). CEC is the soils capacity to hold and exchange nutrients that hold a positive charge known as a cation. Humic acid is a bio stimulant and will promote improved soil microbe diversity and population leading to improved crop nutrition and resistance.

​

Many humic acids have varying quality and crop performance. ABT sources a very high quality humic acid tested to CDFA standards that ensures the product performs to optimal capacity.

​

Affinity Active Humic Acid also contains 6.25% fulvic acid for improved efficacy.
