Humic Acid Fertilizers

Humic acid improves soil cation exchange capacity (CEC) and buffers pH, which indirectly increases the availability of nutrients already in the soil — it's a soil-conditioning mechanism, not a direct-feed nutrient. Effects build over repeated applications rather than appearing after a single dose.

Part of the Biostimulants & Organics range. Biostimulants (amino acids, humic/fulvic acids, seaweed extracts) work by amplifying the plant's natural nutrient uptake efficiency, boosting stress tolerance, and enriching the root zone. Their values build over time to promote long-term plant vitality and soil productivity.
