It is the substance composed by organic products, colloidal in nature which comes from the decomposition of organic remains (fungi and bacteria). The fibrous mass was transformed into coal on which the thin layer of Leonardito was formed.

It is an intermediate material between peat * and lignite **, it comes from the transformations (diagenesis) produced due to the burial of plant remains at depths close to 10m., Where together with the precolation of rainwater and the presence of atmospheric oxygen, gave rise to a progressive enrichment in humic substances.

Se carIt is characterized by its blackish color due to the large amount of carbon it contains.

Throughout the millions of years of its formation, the Leonardito has been subjected to all kinds of physical and chemical, as well as microbiological, actions to reach its current form.

It is mainly found in the upper parts of soils with organic activity.

The organic elements that make up the Leonardite are very stable, that is, their degree of decomposition is so high that they no longer decompose and do not undergo considerable transformation.


Humic acids are a black substance with a high degree of humification and complex structure, which mainly act on the physical and chemical properties of the soil, and which have the following characteristics:

  • They disintegrate clays in very heavy soils with little aeration and give coherence in sandy soils.
  • Increases the permeability and porosity of the soil
  • They precipitate in an acidic medium.
  • Great water holding capacity.
  • Great colloidal action (cation retention), forming part of the CAH. This means that a large number of elements blocked by the ground can be released and made available to plants.
  • Chelating effect with Fe, Mn, Cu and Zn.
  • Maximum cation exchange capacity.
  • Great difficulty concentrating in liquids, 15% maximum because then they begin to leave a lot of lees.
  • They are obtained from leonardites or black mobs.

  • IncreIncreases the cation exchange capacity of the soil
  • Gives consistency to light and compact floors; in compact sandy soils while in clayey soils it has a dispersing effect.
  • Makes it easier to till the land, by improving the physical properties of the soil.
  • Prevents crusting, and compaction
  • Helps to retain water and drain it
  • Increases the porosity of the soil


  • Regulates plant nutrition
  • Improves ion exchange
  • Improves the assimilation of mineral fertilizers
  • Helps with the process of potassium and phosphorous in the soil
  • Produces carbon dioxide gas that improves the solubility of minerals


  • Contributes useful microorganisms to the soil
  • It also serves as a support and food for microorganisms.
  • It does not have harmful seeds (eg weeds) due to the temperature it reaches during fermentation
  • Improves the resistance of plants
  • Improves sexual reproduction.

of use

Always calibrate application equipment

It must be used at a radical level since it presents gradual release and great residual value. It is normally mixed with the fertilizer and incorporated directly into the soil. The humic acids contained in Leonardite improve the properties of the soil due to its high capacity to retain and exchange nutrients.

They form a unique complex with the nutrients of the soil (added or natural), similar to that of chelates, this new complex is very active and easily absorbed by the roots.

Facilitates the incorporation of organic material in the soil, accelerating its decomposition and taking advantage of nutrients.

The high carbon content stimulates beneficial organisms found in the soil, its continued use improves the structure and content of organic matter in it.


In case of poisoning, take the patient to the doctor and show him the package label.

If swallowed : May cause an upset stomach; it is recommended to drink several glasses of water and induce vomiting.

Never drink or induce vomiting to unconscious people.

In case of skin contact : Remove contaminated clothing and wash the affected part thoroughly with plenty of soap and water.

In case of contact with the eyes : wash them with plenty of fresh, clean water for 15 minutes.

In case of inhalation : Remove the person from the contaminated area to a cool place, keeping them at rest. Try to blow your nose.

Always fill the application equipment containers upwind, avoiding spills.

Use the appropriate and complete protective equipment necessary to safely carry out product handling, preparation and application operations such as:

  • gloves
  • mask
  • gogles
  • cotton overalls
  • neoprene boots.

Do not eat, drink, or smoke during applications.

After your work, take a shower and put on clean clothes.

Leonardite is a slightly toxic product, so you should avoid its ingestion and contact with the skin and eyes.
