Liquid humus

CARBOHUMIC is a dense humus extract obtained from lignite. The organic substance contained in the preparation exists in liquid form (humic acids, humins) and solid form (active carbon, biochar). Being an active component of humus, Carbohumic exerts a positive influence on the structure of soil and substrate, stimulates the growth of root system, improves soil fertility and supports plant growth and yield. Applied regularly, it contributes to improvement of soil fertility and increase of humus level in soil. The product is designated for use in cultivation of all species of plants.


Where will you use Carbohumic?

The preparation can be used successfully in horticulture, agriculture, nurseries, amateur gardening in home and allotment gardens as well as for planting in particularly adverse climate or terrain conditions. It is designated for soil application prior to setting up cultivation in order to improve and fertilize substrates and soils, especially degenerated and organically exploited ones, and as top-dressing – through foliar application during plant growth and development. It is recommended for soaking (incrustation during seed, tuber and bulb treatment) of root system of seedlings and roots of various plants. It proves effective for hydroponics container cultures or in organic and ground substrates.

CARBOHUMIC, as the only product originated in Poland, has been qualified on the list of inputs approved for use in organic farming by one of the most renowned institutes in the world, conducting researches in the field of organic farming - the Swiss FiBL


CARBOHUMIC is registered in the list of fertilizers and soil conditioners qualified by IUNG - National Research Institute in Puławy for use in organic farming under the number NE/495/2019

What will you find
in our preparation?


A soft mineraloid of vitreous gloss and black or dark brown colour, whose deposits often accompany those of soft brown coal – lignite – its oxidized form. It is the most concentrated source of humic substances (fulvic acids, humic acids) and humins available in nature, where the content of those substances amounts to as high as 95%. Its properties differs depending on the place of extraction.



The content of carbon in organic matter is the chief determinant of soil fertility. It is an indicator of its quality and of human impact on agricultural and natural ecosystems. Contained in soil, it significantly contributes to the global balance of that element. The most frequent source of organic carbon in soil is the above ground and underground biomass of plants introduced thereinto as well as organic mass introduced as various kinds of organic fertilizers (cow dung and liquid manure) in the form of compost, sewage sludge etc. Organic carbon contained in soil is a highly reactive component, which remains in dynamic balance with the environment.


Active carbon

Often referred to as medicinal charcoal, it designates carbon material of highly developed specific surface area and porosity and thus high capacity for adsorption of chemical compounds from gases and liquids. Main applications of active carbons include removal of fragrances (Carbohumic in connection with natural fertilizers such as cow dung or liquid manure), discoloration, removal of harmful substances from solutions, and even sequestration of CO2 from soil and air. Due to its porous structure, active carbon is capable of adsorption of both organic and inorganic pollutants at a single go.


Micro- and microelements

Lignite is a balanced source of numerous mineral components, so precious for plants, including the most important of the biogenic elements forming organic compounds – carbon (C), but also magnesium, calcium, iron, sulphur, boron, zinc, copper, manganese, molybdenum etc.) of organic origin, and thus much more easily assimilable for plants. Regular supply of nutrients to soils is a key aspect in the context of the proper functioning of plants and the entire soil environment

Product filtration rate and exemplary
range of application

1000 μm / 20 mesh

This is the basic, i.e. the least filtered one – with very high content of organic substance and organic carbon originating from lignite.
This is the base, i.e. the least filtered version of CARBOHUMIC – in the form of the so-called pulp – with a very high content of organic matter, originated directly from brown coal. It is designated to be used in watering cans, water carts (all kinds of field crops; with option of combining with UAN and liquid manure), watering hose (for direct spraying from Mauser container) etc. In other words, all irrigation tools not equipped with filtering systems (or having such systems disassembled).

200 μm / 80 mesh

The intermediate version, offering full application range of the basic version, additionally designated for less precise filters of maximum range 80 mesh (200 µm). Using this version with filters operating above the 80 mesh range may result in their clogging.

100 μm / 140 mesh

Version with the scope of application of the two previous filtration stages, additionally with the possibility of using, for example, in tractors with sprayers with filters up to the 140 mesh / 100 µm. Using this version with filters operating above the 140 mesh range may result in their clogging.

80 μm / 187 mesh

The most filtered version, encompassing full application range of basic and two intermediate versions, dedicated primarily for specialists who use professional irrigation systems (such as drip irrigation lines, sprayers etc.) equipped with finer filters. Product sifting entirely marginalizes the risk of clogging for majority of precision filters available on the market (187 mesh).


Bioactivity of lignite is a few times higher than bioactivity of most common carriers of humic substances such as compost or cow dung

  • Plant vegetation progresses dynamically and harvesting begins even ca. 10 days earlier.
  • It provides an effective method of fertilizing the soil and enriching it in natural humic substances and mineral components.
  • Humic acids enhance the effectiveness of pesticides, herbicides, fungicides and limit their detrimental impact on the environment.
  • The dark colour of the preparation attracts sunlight and thus accelerates soil warming in spring and autumn, which extends vegetation period.
  • Despite the fact that the concentrate itself does not contain any living organisms (it is not a bacterial preparation), it decidedly contributes to the creation of such organisms. The preparation allows the ecosystem to regenerate naturally in a fairly short time – without any addition of chemicals and in manner which is entirely harmless to biological life. The product can be used with bacteria strains for decomposition of post-harvest waste or UAN.
  • The active carbon contained in the preparation features antiseptic properties: it not only captures pollutants from the air but also protects plants against diseases, fungi, pests and harmful microorganisms.
  • Humic acids aerate the soil and improve its structure. Water, nutrients and the root can penetrate the soil freely.
  • Application of humic acid stimulates cell walls of seeds and accelerates metabolism thus extending the germination period.
  • Humic acids contained in the preparation chelate nutrients available in the soil, especially iron, into forms easily assimilable by plants. Chelated components optimize plant nutrition, which leads to a possibility of economizing up to 30% of the outlays on plant pretection products and chemical fertilizers.
  • Accumulation of organic matter in the form of supplied humic acids prevents rapid permeation of water to deeper soil layers, particularly in the event of light soils. Through their swelling the humic colloids bind water and thus water consumption can be reduced by as much as 50%, which is important particularly in the regions threatened by drought.
  • Regular application of humic acids successively influences the quality and volume of crops (increase as high as 20 %), which translates directly to cost efficiency of cultivation.
  • Higher content of organic matter enhances the taste of harvested crops as well as boosts their content of vitamins and mineral salts and thickens cell walls in fruit, which facilitates better storage, resistance to damage and trade durability.
  • CARBOHUMIC is a certified preparation approved for use in organic farming, which expands the potential and sales attractiveness of harvested crops.
  • Higher soil fertility, which depends on the properties of organic matter contained therein, means higher production capacity.
  • Increased content of organic carbon favours binding nitrogen and phosphorus in upper soil sections and leads to decreased solubility of their mineral forms.
  • Humic acids are a natural adsorption buffer that prevents excessive salinity of soil (e.g. ammoniated form of nitrogen NH4+) which is unfavourable to the growth and physiological functioning of root system.
  • Humic colloids countervail soil erosion (water and air) and at the same time stimulate the growth of root system, particularly the root hairs.
  • In contrast to mineral fertilizers, liquid humus does not entail the risk of overfertilization as it is a natural organic substance and does not require any preharvest interval.
  • Humic acids support plants’ immune system thanks to which plants are less susceptible to unfavourable weather conditions (such as frost or water shortages), pests, fungi and diseases.
  • CARBOHUMIC contributes to increased activity of useful soil microorganisms and beneficial biological balance in the root system zone; it also contributes to greater biodiversity.
  • The preparation allows the soil ecosystem to regenerate within a short time in a natural manner – without chemicals – and in a manner that is totally harmless to biological life.
  • Elements harmful to plants, animals and humans such as: aluminum and a range of heavy metals are not absorbed by plants as they are bound by carbon (C) and neutralized by microorganisms.
  • The preparation facilitates climate protection through CO2 sequestration: it is estimated that a dose of 13.5 t/ha of organic carbon directly into soil (which corresponds to 3% of top layer of 30 cm in depth) ensures carbon storage for at least two centuries and, what is more, carbon stored in soil remains chemically stable for millenia.
  • As little as 1 g Corg contained in the preparation is sufficient to cover an area of an acre (4000 m2).
