摘要：
A foaming granule is provided that includes an acid, a gas-evolving acid neutralizing agent, a surfactant foaming agent, and an active agent that is a plant growth enhancer, pest control agent, de-icer or anti-icer. Upon wetting a granule, the acid and neutralizing agent are brought into contact releasing gas that is trapped in the surfactant to form a foam that disperses the active agent to a greater area and more uniformly than a conventional nonfoaming granule containing a like amount of active agent. Dispersal of granules followed by sufficient time for foaming to occur represents a typical use methodology.
