COMPLEXOR HUMMUS – a natural calcium carbonate derived from lacustrine chalk,
enriched with humic acids and organic carbon, improves soil pH and enhances its
fertility. Thanks to its granulated form, it ensures convenient and precise
application. Reactivity at the level of 90%. It improves soil pH in the root
zone and provides calcium.
- Variety: 07a (natural mineral without magnesium addition)
- CaO Content: 41–50% (equivalent to approx. 80–90% CaCO3)
- Reactivity: 90% – fast action in the root zone
- Contains: Humic acids, fulvic acids, organic carbon
Benefits of Use
- Immediate activity in the soil environment: thanks to the high solubility of components in soil water, the fertilizer shows a rapid agronomic effect without the need for a long incubation period.
- Effective pH correction: the preparation intensively neutralizes soil acidity, restoring the soil to its optimal pH level, which ensures proper uptake of macro- and micronutrients by plants.
- Increased efficiency of plant nutrition: raising soil pH allows better absorption of nutrients (N, P, K), which translates into intensified growth processes and the development of both biomass and root systems.
- Improvement of soil physical parameters: the presence of organic carbon and humic substances promotes soil particle aggregation, creating a stable crumb structure that results in better water retention and enhanced gas exchange.
- Detoxification of the soil profile: the product effectively binds and neutralizes toxic heavy metal ions (e.g., aluminum, cadmium), reducing their mobility and harmful effects on cultivated plants.
- Stimulation of microbiological activity: the presence of humic and fulvic acids supports the multiplication of beneficial microorganisms, enhancing processes of mineralization and humification of organic matter.
- Increase in soil organism activity: improved habitat conditions favor the development of soil mesofauna (e.g., earthworms), which physically improve soil structure by increasing porosity and aeration.
- Synergistic effect with mineral fertilizers: the application of COMPLEXOR HUMMUS increases the efficiency of NPK fertilizers by eliminating physicochemical blockages resulting from low pH and excess antagonistic ions.
- Increased crop productivity: depending on soil type and cultivation technology, product use can increase yields by 0.5–2.0 t/ha, significantly improving the profitability of agricultural production.
Instructions for Use
APPLICATION: PRE-SOWING OR TOP-DRESSING, AT DIFFERENT TIMES OF THE YEAR:- Early spring – pre-sowing applications around the root system
- Early spring – on meadows and pastures
- Spring – top-dressing (even spreading thanks to different granule sizes)
- Autumn – after harvest, mixed into the soil up to 15 cm
- Autumn – on meadows and pastures
- Autumn – after plowing, spread on the surface
Precautions
- When used as intended, the fertilizer poses no hazard.
- For prolonged contact, the use of eye and respiratory protection is recommended.
- In case of eye contact, rinse thoroughly with plenty of water.
- WARNING: DO NOT APPLY SIMULTANEOUSLY WITH MANURE, SLURRY, OR NITROGEN FERTILIZERS (OBSERVE AN INTERVAL OF AT LEAST 3–4 WEEKS).
