Florahumus humic acid biostimulant for improved nutrient uptake and reduced fertilizer use in row crops
Florahumus is a humic acid-based biostimulant extracted from lignite sourced directly from our own mine. Field trials on winter oilseed rape show that applying Florahumus alongside NPK fertilization reduced by 40% maintained comparable crop yields to standard full fertilization, while also improving soil structure and crop resilience. Certified for organic farming, the product offers growers a path to lower input costs and more sustainable production.
Overview
Florahumus is a humic acid-based plant biostimulant developed by Kopalnia Węgla Brunatnego Sieniawa Sp. z o.o. The product is derived from high-quality leonardite extracted from the company's own lignite mine in the Lubuskie region of Poland, giving full control over raw material quality and supply.
The core value proposition is improved nutrient uptake efficiency in row crops. In field validation on winter oilseed rape grown on leached light clay soil, Florahumus applied as a foliar spray alongside NPK fertilization reduced by 40% produced yields of 3.52 tonnes per hectare, comparable to the reference plot receiving 100% NPK fertilization at 3.67 tonnes per hectare. The full NPK plus Florahumus treatment reached 4.07 tonnes per hectare, indicating an additional yield benefit when the biostimulant is layered on top of standard fertilization.
Beyond yield, Florahumus is positioned to improve soil structure, support root development, and help crops tolerate environmental stressors such as drought and intense sunlight. The product is certified for use in organic farming, making it relevant to both conventional growers seeking input efficiency and organic producers seeking approved biostimulants.
Technical specifications
- Active ingredient: humic acid derived from leonardite (lignite) sourced from the Sieniawa mine
- Form: sprayable biostimulant applied as a foliar treatment
- Validated application protocol on winter oilseed rape: three foliar sprays of 200 g per 1000 litres of water, timed at the 6-leaf rosette stage, after spring onset of vegetation, and at the flower bud stage
- Fertilizer interaction: demonstrated compatibility with both full and reduced NPK programs; maintained yields with 40% less NPK in trial conditions
- Soil and crop fit: tested on leached light clay soil in the rye agricultural usefulness class; intended for row crops with potential extension to other crops and organic livestock farming systems
- Organic certification: approved for use in organic farming
- Distribution support: regional advisor network plus marketing and logistics support for distribution partners
Technology readiness level
Florahumus is a commercially available product with completed field validation on winter oilseed rape. Trial plots of 120 m² demonstrated that the biostimulant can maintain yields when NPK fertilization is reduced by 40%, and can increase yields above the standard fertilization reference when used as an additive.
Planned next-stage validation includes broader testing across additional crops, soil types, and climatic conditions, as well as evaluation of Florahumus in organic livestock farming for its potential to neutralize toxic substances in manure. These expanded studies will further characterize the product's effectiveness and open additional application areas for partners and growers.
