What is LEONARDITE?

WHAT IS LEONARDITE?
 

What is Leonardite

Leonardite is a low rank coal derived from prehistoric plant matter. It is found as outcropping of lignite deposits, usually very close to the surface. It differs from lignite by its high oxidation degree and the higher carboxy groups. Due to the large amount of living bacteria, Leonardite was formed instead of coal in certain sedimentation layers. Being a highly decomposed compressed natural organic humus that has been further processed by microbial activity, Leonardite has a high humic acid content which is one of the most bio-chemically active elements.

The composition of Leonardite will show on average organic matter 75-90%, aluminum, nitrogen, phosphorus, potassium, sulfur, iron and calcium less than 1%. Since Leonardite is a naturally mined material, the composition of Leonardite differs slightly throughout the deposit and from deposit to deposit.

 

Leonardite is a natural form of humates, completely organic in nature and beneficial in a wide variety of applications. Numerous tests have been conducted which substantiate the fact that our Leonardite consistently shows higher levels of carbon content, resulting in a higher humic content.

Leonardite is a soft waxy, black or brown, shiny, vitreous mineraloid  that is easily soluble in alkaline solutions. It is an oxidation  product of lignite, associated with near-surface mining . It is a rich source of humic acid  (up to 90%)and is used as a soil conditioner , as a stabilizer for ion-exchange resins in water treatment,in the remediation of polluted  environments and as a drilling  additive.

Why Humic Acid from Leonardite

 

The maximum saturation we have been able to achieve with highly active humic acid is 15%. Humic acid salts begin to precipitate if we increase the solids content above this figure. Any humic acid product that claims to contain more than 15% humic acid solids actually contains a smaller percentage of active acids plus inactive and often times insoluble particles. The inactive and insoluble portions add nothing to the solution but instead plug irrigation and spray distribution equipment.

Humic acid extracted from manure or peat is usually not as effective in absorbing micronutrients as humic acid originating in leonardite. Similarly, lignite-based humic acid performs poorly as a growth stimulator unless it is partially oxidized. This usually adds considerably to the product's cost. Leonardite has been oxidized by nature, resulting in a highly active humic acid at reasonable cost. Humic acid extracted from leonardite is an excellent balance of effectiveness and low cost.
