Multi-phase material-containing compositions and related methods of preparation and use

A method, comprising:

• heating at a temperature of at least 90° C. for a time of at least 10 minutes and a pressure of at least one atmosphere:
• 1) a potassic framework silicate ore;
• 2) at least one material selected from the group consisting of an oxide, a hydroxide, and a carbonate of at least one of an alkaline earth metal and an alkali metal;
• and 3) water, thereby producing a first product;
• drying the first product to provide a second product;
• and
• combining the second product with a source of a component to provide a composition comprising the MPM and the component,
• wherein the source of the component comprises at least one member selected from the group consisting of KCl, a macronutrient source, a micronutrient source and a source of a beneficial element.
