Premium quality fertilizer for commercial cultivators
A fully solubilized liquid fertilizer with humic and amino acids, compatible with root, foliar, and hydroponic application. One formulation covers every stage, nothing else to buy or switch.
Twenty-five years of proven technology.
25+ years of proven industry leadership
Over two decades of rigorous field trials and laboratory refinement.
U.S. patented technology
Advanced technological processing of poultry feathers into a premium quality fertilizer, protected and verified.
Advanced technology
Harnessing the power of science to support nutrient uptake. Thanks to ROKOSAN’s unique formulation, Rokosan products perform comparably to conventional fertilizers in Rokosan field trials.
Patents & certifications
Patented in the United States, China, Russia and Ukraine. Certified for agricultural use in 18+ countries, including U.S. registration.
The premium 4-in-1 technological superiority
One homogeneous liquid, four components. Enzymatic hydrolysis of poultry feathers yields a complete plant-nutrition matrix: no blending, no separate additives, no residue.
NPK balanced nutrition
3.9-2.5-3.9: essential macro-nutrients for steady, non-burning uptake.
18 amino acids
Amino acids that support plant nutrition and tolerance to environmental stress.
Humic acid complex
Improves cation exchange capacity (CEC) and mineral chelation in the root zone.
Ready-to-use, system-safe
Designed for drip, pivot and foliar sprayers, a homogenized liquid built for standard nozzles and filters.
Built for how your operation actually runs
One product, every stage
Root drench, foliar spray, or hydroponic feed: no separate SKU per growth stage, and nothing to juggle across your team.
Less time, less training
One tank-mix protocol and one reorder point, instead of coordinating storage and staff training across multiple inputs.
Ready-to-use convenience
A stable concentrate built for standard dosing equipment: no custom blending or on-site formulation required.
Tank-mix compatibility (zero extra labor)
Engineered to tank-mix seamlessly with standard fungicide, herbicide, or insecticide passes. Growers incur zero additional labor or tractor fuel costs when applying Rokosan during scheduled passes. As with any liquid input, avoid mixing with calcium-based products and use caution with magnesium-based products; see the Tank-Mix & Pesticide Compatibility guide for details.

A patented technology, now serving U.S. growers
Rokosan has spent more than two decades developing amino-acid and humic-acid based plant nutrition, growing into one of Europe’s leading producers of natural-mineral liquid fertilizers and serving commercial farmers, greenhouse growers, and agricultural distributors across more than a dozen countries. The company, founded in 1999, is based in Sečovce, Slovakia.
At the center of Rokosan’s technology is a patented enzymatic hydrolysis process that converts poultry feathers, wool, hooves, and horns (byproducts of the livestock industry) into a fully solubilized liquid fertilizer rich in amino acids, humic acids, and balanced NPK nutrition. The process is patented in the United States, China, Russia, and Ukraine, and the resulting product line (marketed under the Rokohumin, Rokolan, and Rokoaktiv trademarks) is certified for agricultural use in 18+ countries across Europe, Africa, and the Americas, including Canada, Colombia, Cuba, and Panama.
Rokosan’s approach to converting animal byproducts into liquid crop nutrition has been recognized internationally: the company was selected among the EU Gateway Program’s Top 30 waste-recycling technologies (2011 and 2017), invited to present at the U.S. Select Summit as the only animal-waste processing technology from the V4 region (2013), named to Life Science Review Journal’s Top 10 Agribiotech Companies in Europe (2023), and awarded Slovakia’s Energy Globe National Award (2022) for its environmental impact. Rokosan is also a founding member of the Association of Organic Fertilizer Producers of Slovakia (AVOH). View all patents & certificates →
