Technology

ProtoHumiX® is produced under licence of European Patent EP3135655.

Patented production

• European Patent EP3135655
• Patents and patent protection in the USA, Japan, Canada, Australia / New Zealand, Israel, South Korea, India, Indonesia, Vietnam, and other countries

Unique equipment

The equipment is specifically designed for producing humic and fulvic acids under the conditions described in the patent. This supports consistent quality and high purity, suitable for modern and precise application.

What distinguishes ProtoHumiX® technology

The patented technology enables the production of humic and fulvic acids with very high purity and full bioavailability of the active water-soluble fractions.

Through a precise and controlled process, unwanted impurities are minimized. In standard extracts, these impurities can:

• affect product safety
• make fine application more difficult (nozzles, drip systems, drones)
• limit the range of applications

The result is a stable product suitable for modern and precise agricultural technologies.

For sustainable agriculture

ProtoHumiX® technology is aimed at long-term solutions in agriculture and enables:

• restoration of depleted and degraded soils
• support for production in low-fertility regions
• improvement of soil structure and water regime
  (within good agronomic practice)
• significant yield increase

Technical specification

Composition

• Total organic matter: 31.9 %
• Humic substances – total: > 11.5 %
• Humic acid (active fraction): > 10.1 %
• Fulvic acid (active fraction): > 1.4 %
• Hymatomelanic and ulmic acids: 2.0 %
• pH (0.5% solution): 8.5–9.2
• K₂O: 1.7 %
• P₂O₅: 1.1 %
• Organic carbon content: 17.9 %
• Total nitrogen content: 0.74 %

Organic matter and organic carbon are stated on a dry matter basis, according to laboratory report PL/685/2025/AP. The humic-substance, humic-acid and fulvic-acid contents are on a dry matter basis; these three contents and the pH of a 0.5% solution follow the safety data sheet, section 3.3 (page 6). Laboratory results are separate measurements and must be read on their stated basis. Follow the label and accompanying documentation for each batch.
