In North Dakota, a formation of this highly oxidized lignite was called leonardite after the geologist, Dr. Leonard, who discovered it. This material was more highly oxidized than other lignite’s and consists of as much as 85% humic acids. Leonardite as a source of humic acids for crop production was discovered in the 1960’s. Researchers at the US Bureaus of Mines began to experiment with applications of crushed leonardite to agricultural soils. They found that applications of the material. at rates of 100 to 2,000 per acre, increased yields of potatoes, sugar beets and other crops. Various universities and extension services began to experiment with the use of leonardite based soil amendments and fertilizers. In particular, the South Carolina Experiment Station demonstrated spectacular yield improvements from formations in New Mexico. It was apparent that this source was more biologically and chemically active than the North Dakota source. Since those early experiments in the 1960’s, university researchers throughout the world have continued to study humic acids derived from leonardite.

Why is Leonardite an Ideal Humic Acids Source?

Leonardite has the highest humic acids content of any natural source. 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. The positive response of plants and soils to humic acids derived from leonardite have been demonstrated by many researchers. There is abundant evidence from field trials with humic acids from leonardite that prove the value of leonardite as a humic acids source.

What is Leonardite?

Many thousands of years ago large bodies of water existed where huge quantities or organic matter were deposited and began to slowly decompose. Over the year, giant peat bogs were formed. Through geologic activity many of these bogs were buried. After burial, the organic material began to lose oxygen and be transformed in coal under heat and pressure. Those deposits that were never buried deep enough to undergo the complete transformation into coal, became leonardite. Today these leonardite ores exist as stratified layers of brown to black coal-like material underneath an overburden of inorganic soil or rock.

Humic Acids & Seaweed Extracts, When used together… work 50% More Effective Than Either Product Alone. Work 50% more effective than either product alone. “

Why use Leonardite in Sportsturf?

CHELATORS Greatest Value as Chelators. Humic and Fulvic are great Chelators, they have functioning groups that act as claws, holding mineral ions strongly enough to keep them from reacting with each other and becoming unavailable to the plant, but weakly enough so that they can be released to the plant on demand.
CARBON SOURCE: We must put Carbon back into our agronomy practices in an efficient & readily available manner, while reducing dependancy on synthetic fertilisers and chemicals
FIXES SALINITY ISSUES: Humic products are extremely efficient in combating salinity issues that arise from heavy use of synthetic fertilisers.
FEED SOIL MICROBES: Feeding soil microbes a massive amount of Carbon (their primary food source) along with Energy and Oxygen necessary to respire the food, stimulates massive root growth. larger root systems means more water and nutrients available for sugar production = Increased growth.
SOIL CONDITIONER: Improves soil structure. Increases Cation exchange capacity of soil.
Enhance nutrient uptake and increases the content of humus in soil
Reduces the poisoning of pesticide residues
Improves the physical and chemical quanities of soils.
Plant growth stimulant, promotes root development and stimulates seed germination.
Enhance nutrient uptake by combining nutrients and humic acids and keep a well balanced nutrition.
Fertiliser effectiveness promoter. Greatly boosts the usage rate of nitrogen fertiliser. Keeps 60% of nitrogen easily offered and as 40% slow release.
Potassium is an important element of chlorophyll, accelerates the photosynthesis
Increases water holding capacity
Increases aeration of soil
Builds organic matter
SB Foundation available in granular forms of different sizes, very low dust.
