Apart from the usual mining activities Kopalnia Węgla Brunatnego Sieniawa Sp. z o.o. [Sieniawa Mineworks Ltd.] runs constant research to expand our trade offer even further. One of our finds is the utilization of brown coal in farming through the production of humic acids to improve weak soils.
What are humic acids?
Humic acids, also known as humus acids, are a mixture of large-particle organic compounds of varying composition and acidic factor, composing the humus and ground water solutions.
Produced by the biochemical decomposition of organic compounds, they are encountered in their raw state, i.a., in therapeutic muds, soils, organic fertilizers, peat, lignites and brown coal.
How do they work?
Humic acids are used in farming owing to their unique characteristics. First and foremost, through the decomposition of organic compounds, they support the growth and development of favorable microorganisms, increasing the humus content of the soil, improving its physical properties, and thus raising its quality and productivity.
The compounds also have an impact on the chemical structure of the soil, improving permanently its qualities and neutralizing acidic and alkalic soils owing to mechanisms of pH factor regulation.
Their ability to form chelate compounds with microelements and improve the intake of nutrients by plant cells also stimulates the activity of growth-supportive microorganisms and the production of plant enzymes. Further, their presence also supports increases water and nutrients intake in the plants themselves and increases the buffering characteristics of the soil.
Concluding, humic acids are used in farming principally owing to their ability to improve the quality of soil, and thus to improve production, coupled with an increase of nutrient content in the produce.
How do humic acids affect the environment?
As a completely natural product, humic acids present no threat to the natural environment. Quite contrary, their ability to adsorb organic compounds has led to their utilization in the detoxification of waters, soils and silts from pollutants of this type.
Another important characteristic of humic acids that allows for their inclusion in the ranks of environment-friendly factors is their ability to bind and slowly release the insoluble metallic, oxide and hydroxide ions. Thus, their presence contributes to a decrease in the toxic substance content in plants.
Finally, it has to be said that well-developed root systems in humic acids-rich soils prevent the diffusion of nitrates and pesticides to ground waters, thus reducing the problem of salt factors linked with the application of water-soluble chemical fertilizers.
In summary, humic acids:
- prevent the loss of nutrients from sandy soils;
- improve the physical and chemical characteristics of soils;
- improve soil ventilation and water retention in heavy soils;
- reduce soil breakage and erosion;
- play a vital role in the decomposition and release of organic substances, and thus improve soil saturation and arability;
- work in a completely natural, environment-friendly way.
KWB Sieniawa is currently looking for Poland and all over the world humic acids production and distribution partners. Apart from high-quality raw product, our offer also includes marketing and promotion support, as well as sharing our know-how on the construction of efficient trade channels.
