leonardite is used to condition soils either by applying it directly to the land, or by providing a source of humic acid or potassium humate for application thanks to having the highest humic acids content of any natural source. . it adds the organic matter to soil, hence sodic and calcareous soils are benefited from it highly. it also supplies ideal conditions for “good” bacteria to grow. leonardite adds organic matter to marginal soils improving texture, moisture holding capacity and ph stability. as a fertilizer enhancement, leonardite improves a crop’s ability to absorb nutrients, resulting in faster growth, healthier and higher yields. although humic acids can be extracted from peat, composts or soils; none of these sources are so concentrated and abundant as leonardite. it is plentiful and inexpensive compared to other possible humic acid sources.
oil field
leonardite is called as lignite and is widely used in water – based drilling mud when it is used in the oil field. the properties of it makes it easy in fluid loss control, serve as clay deflocculants and improve filter cake quality. lignite can be blended with caustic soda, and because of its unique organophilic properties leonardite, or “lignite”, can also be modified for use in oil based drilling fluids.
foundry
leonardite is used as an additive in green sand molding in foundries. it reduces clay viscosity, increases mold permeability, absorbs and retains water and improves mold shakeout. it helps to improve the foundry environment for employees working in the plant.
soil remediation
leonardite can be added directly to soils to reduce the take up of metals by plants in contaminated ground, particularly when combined with compost.
