about us

Leonardite Products mines and processes leonardite, oxidized lignite, found east of Williston. Processed leonardite is used as an additive to oil drilling fluids and fertilizers. It is used for soil amendments and is being tested for soil and water remediation applications. The agricultural line of products is generally sold to fertilizer blenders and available in several dry forms under the trade name Source. The liquid products are called Humi-Source and Humi-Source Plus. Both products are organic in nature and certifiable. The oil field line of products is called Len-Ox and is also available in several grades. Both lines are sold domestically and internationally.
