From nature — for soil, plants and animals.

Humic acids are natural organic compounds that form the foundation of soil fertility. They are complex mixtures formed during the decomposition of biological matter (humification), obtained from the most calorific sources such as leonardites — young brown coals.

Their main biologically active fractions are humic, fulvic, hymatomelanic and ulmic acids. These compounds work on many levels: they improve soil structure, increase its water retention capacity and support the uptake of micro- and macroelements by plants.

They are a response to the progressive degradation of soils caused by excessive use of synthetic chemicals, in the direction of sustainable, profitable agriculture. Effectiveness rests on three measurable pillars:

• Detoxification and safety: they act as powerful natural filters, binding toxins, heavy metals, pesticide residues and radionuclides into stable complexes unavailable to plants.
• A leap in efficiency: humic acids can increase crop yields from 10% up to 50%, significantly raising farm profitability.
• Reduction of operating costs: they allow optimizing and reducing the use of traditional mineral fertilizers and agricultural chemicals by up to 30%, while maintaining or increasing yields.

The technology is under international patent protection (WIPO: WO2015/163785), covering both the mechanochemical extraction process and the dedicated production equipment. What is documented:

• Ultra-high laboratory-tested purity: an extract free of harmful ballast impurities and heavy metals, confirmed by certificates — the European CE mark as an Inorganic soil improver (No CE-B/5/26/BS) and as a Plant biostimulant (No CE-B/17/25/BS).
• Biological activity: the concentration of free, 100% water-soluble active acid fractions corresponds to the total extract concentration — there is no ballast fraction diluting the effect.
• Usability and safety: the dedicated purification method eliminates the risk of clogging sprayer nozzles and irrigation (fertigation) systems — a common problem with traditional humates.
• How this differs from potassium humate: potassium humate is the potassium salt of humic acids, usually traded as a powder or granulate. ProtoHumiX® supplies the free acid form as a liquid — the same class of active substances, but without the added potassium and without the loss of solubility that salts show in alkaline soil. If you are comparing potassium humate, you are comparing a different chemical form of the same substance class.

The optimal schedule depends on the specific crop, but we most often recommend 2 to 4 treatments per growing season to maximize effects.

Humic acids are applied using three main agrotechnical methods that can be adapted to the specifics of the crop:

• Pre-sowing application (seed and tuber dressing): seeds can be soaked in a 0.1% aqueous solution (6–12 hours depending on species) or ProtoHumiX® can be added directly to standard liquid seed dressings.
• Foliar spraying (during vegetation): the most common and cost-effective method in broad-acre farming. Standard operational dose: 1 l of product dissolved in 300–400 litres of water per 1 hectare. Can be combined in tank mixes with fertilizers, insecticides and fungicides.
• Fertigation (soil and drip irrigation): full water solubility allows precise delivery directly to the root zone. Recommended in intensive vegetable growing and orchards.

Overdosing pure ProtoHumiX® humic acids in agricultural and breeding practice is practically impossible.

• Toxicological safety: these products are highly safe substances, completely devoid of carcinogenic, embryotoxic, allergenic and anaphylactogenic properties.
• Huge margin of safety: animal studies showed the clinical poisoning dose for 50% of subjects is as high as 7.5 g per 1 kg of body weight, while the recommended dose is only 10–20 mg.
• No negative impact on the agroecosystem: humic acids are not xenobiotics. Even in doses exceeding recommendations, they do not cause phytotoxicity or damage the natural environment.

Two CE certificates issued by PCBC (under European Regulation 2019/1009) document officially verified effectiveness and purity, as well as the product's dual functionality, based on patent EP3135655.

• Certificate CE-B/5/26/BS (PFC 3B: inorganic soil improver): confirms ProtoHumiX®'s technological capabilities to increase water capacity, improve structure, chemically buffer pH and reduce heavy metal mobility in soil.
• Certificate CE-B/17/25/BS (PFC 6B: non-microbial plant biostimulant): formally confirms the product's impact on stimulating and accelerating plant growth.

The high quality of our extraction technology (patent WO 2015/163785 A1) is proven by hard data. We have documented field results from different climate zones and continents:

• Maize (Austria): application of only 1.25 l/ha saved the crop and yielded 4.63 t/ha in extreme drought conditions on clay-stony Alpine upland soil — the control trial yielded nothing.
• Potatoes (Kuras variety): a 44% efficiency increase, generating a surplus of 11 tonnes per hectare.
• Sugarcane (Barbados): a 28.89% jump in yield mass (from 45 to 58 t/ha), translating into a 28.57% increase in total pure sugar yield.
• Winter wheat (Russia, Yuka variety): 32% higher yields (from 49.8 to 66.0 dt/ha) plus significantly higher grain quality (protein, gluten).
• Spring wheat (Canada, Alberta): a solid 25.5% yield increase (from 47 to 59 bushels per acre) on chernozem soils.
