Plants are grown in soil which has been intimately contacted with water containing a catalytically effective amount of a novel catalyst to improve the fertility thereof. In a preferred variant, the water which is intimately contacted with the soil may also contain catalyst treated lignite. Plants grown in the treated soil are more vigorous and resistant to disease or adverse environmental conditions. The yields are higher in instances where the plants are grown commercially for food or fiber, and the plants have a more pleasing appearance in instances where they are grown for decorative purposes. The catalyst is prepared by a process including the steps of admixing a water soluble alkali metal silicate with an aqueous medium containing carefully controlled amounts of water soluble substances which are sources of calcium ion and magnesium ion, reacting the same to produce an aqueous colloidal suspension of the reaction product, admixing a micelle forming surfactant with the aqueous medium, and agitating the aqueous medium containing the colloidal particles and surfactant to form catalyst containing micelles. The catalyst treated lignite is prepared by a process including intimately contacting lignite with an aqueous medium containing the novel catalyst until it is soluble. Presently preferred processes for preparing the novel catalyst and the water soluble catalyst treated lignite are described.
