Compositions and methods for dust control

A method of dust control, comprising:

• determining a temperature of use;
• selecting an amount of nitrogen and calcium sources and an amount of enzyme to solidify a slurry within a particular time frame based on the temperature of use, the nitrogen source comprises urea;
• creating a composition that includes the amount of nitrogen and calcium sources and spores for producing the amount of enzyme, the spores comprise spores of a urease-producing microorganism;
• distributing the composition over a surface, the distributing the composition includes distributing the nitrogen and calcium sources in a timed-release form with a pre-determined rate of dissolution;
• germinating the spores on the surface to produce calcite to form a self-renewable crust at the surface;
• and
• generating the slurry to recreate the self-renewable crust at the surface by applying water to the surface without the reapplication of the composition to the surface.
