AGT-50 is one product uniquely designed for all growing mediums. Particularly for soil, AGT-50 encourages healthy diversity. It stimulates plant growth and strong root development to increase yield, reduce waste, and maintain high nutrient levels. 



AGT-50™ delivers more benefits than humic products. Yes, humic acids contain fulvic acids to a small degree; however,  AGT-50™ is fulvic dominant, including 13 additional organic acids that co-reside in the raw material and provide tremendous benefits to growing plants from drought resistance to better photosynthesis with earlier blooms and fruit. 


For vegetative growth, one gallon of AGT-50™ makes 3,840 gallons of feed solution. In liters that's 3.8 L to 14,536 L!  Far less is applied than other brands to achieve the same or better results. It is versatile, potent, stable in liquids, and easy to add to your protocol.


Use AGT-50™ is as a soil amendment and foliar spray that accelerates your nutrient regimen. Due to the potency of our source product, it is very economical to use.


Foliar Spray Note: Fulvic molecules are smaller than humic acid molecules. Thus fulvic acid is a better choice for a foliar spray and delivers nutrients and protection to the leaves and stalk. It is not recommended to spray during peak sunshine.




We use filtered water and proprietary methods to extract 33 organic acids and over seventy trace elements and minerals. Our raw material is such that no chemicals are needed in the extraction process. Water is the only substance that contacts our deposit material. Good for you, your workers, the environment and compliant with USDA Organic certification.


AgTonik, an affiliate of Mineral Logic, employs independent lab testing, since 1994, for pH, total dissolved solids, electrical conductivity, fulvic mineral content, amino acid profile, organic acids, hydrogen, nitrogen, carbon, heavy metals, mineral and trace elements, as well as mold, microbes, harmful chemicals, and other contaminants.


USDA Organic Note: The FDA does not provide organic certification of fulvic acid products, minerals, or trace minerals, because minerals and organic acids are not grown, like a crop, which must follow a stringent protocol of acceptable practices to ensure its purity. OMRI, the Organic Materials Review Institute, has reviewed AGT-50™ its constituents, and our extraction methods, and lists AGT-50™ as compliant with the USDA Organic criteria to use in growing organic crops.


AGT-50 is of organic origin from millions of years of plant and animal matter composting. These nutrients are being depleted in our soils by poor farming practices and synthetic fertilizers that do not consider the importance of biodiverse soil, plentiful microbes, and trace elements.


Our products have fulvic acid potencies from 80H to 10H on a hydrometer scale. We can customize formulations anywhere from 1.5 to 12.3 pH.


All of our liquid fulvic products will remain suspended in solution. Plus the naturally acidic pH maintains the product’s antiviral, antibiotic and antifungal properties.


Past performance data indicates 1 quart per acre per season provides optimal results.
