BioLiNE® Gold Fulvic Acid
An effective and affordable tool for helping growers manage their crops.
A purified and concentrated liquid fulvic acid that is recommended for use with all fertility programs to boost crop yield and vigour. BioLiNE® Gold can be used on any crop grown either in soil or hydroponically. It can also be used as an ingredient in seed treatments to enhance germination and early plant development. For field crop usage, it can be applied to the soil in-furrow, banded, or side-dressed; it can also be applied by fertigation or as a foliar spray.
Product Benefits
- Rapid and Even Emergence – Improves water penetration through the seed coat and helps moisture move evenly through the seedbed, leading to more synchronized imbibition (water uptake), so seeds begin the germination process at the same time.
- Abiotic Stress Resistance – Improves water-use efficiency by reducing cuticular transpiration and stomatal conductance, and dramatically enhances antioxidant enzyme activity necessary to control the buildup of reactive oxygen species (ROS), thereby lowering lipid peroxidation.
- Nutrient Assimilation and Transport – Forms stable complexes with nutrients, making them more soluble and readily available for plant uptake. Increasing the permeability of plant cell membranes and improving the uptake of nutrients by plant roots.
- Soil Microbial Population – Enhance soil biology around the seed by acting as a carbon source for beneficial microbes, supporting a more active microbiome in the rhizosphere and improving overall soil structure.





Recognition of Excellence
Not all labels are alike and varied claims regarding content can be confusing to consumers.
The only biostimulant product to have both EU and US certifications.

The Certified Biostimulant program is a U.S.-based certification program (administered by The Fertilizer Institute) that is used to certify products that meet industry standards for efficacy, safety, and composition. BLG was certified in October 2024 for biostimulant claims of:
- Improving abiotic stress tolerance
- Increasing nutrient use efficiency
- Improving crop yield
- Increasing root development

For certification, plant biostimulants have to meet not only the EU safety, health, and environmental protection requirements, but also prove the effectiveness of the biostimulant claims on the label. BLG was certified in October 2023 for PFC 6.B (Non-Microbial Plant Biostimulant) with claims of:
- Improving tolerance to abiotic stress on all 42 broadacre and 83 vegetable, ornamental and AMP crops
- Improving nutrient use efficiency for nitrogen, phosphorus and potassium for broadacre crops
- Increasing number of seeds/plant, pods/plant, ear size, plant weight, root growth and crop yield on all broadacre crops
- Increasing marketable yield, average fruit weight, plant weight, root weight, and chlorophyll

The HPTA Test Method Certified® Seal demonstrates that the products bearing the seal meet a high-quality standard. The HPTA Test Method Certified® Seal puts everyone on notice, including consumers and governmental officials, that the advertising claims related to the content of humic and fulvic acid have been verified employing scientific standardized procedures.
