Abstract

An activated-release, water-insoluble or slowly-soluble coating is utilized on fertilizers, pesticides, seeds, medicine, and other granules to precisely time the release of the active ingredient of the granules, for purposes such as fertilizer and pesticide release as well as to initiate seed germination. An external stimulus, or activating agent, including, but not limited to, microwaves, ultrasonic waves, X-rays, radio waves, electromagnetic waves, radar waves, sonar waves, magnetic induction, (or pulses of any of the foregoing), specific chemical, bacteria, or fungus organism (such as ionic or non ionic surfactants, organic solvents, specifically cultured bacteria, fungi or catalytic agents) is used to break the coating, thus allowing for the release or germination. An activating device may be mounted on or in a tool bar, cart, or other apparatus pulled by a tractor, all-terrain vehicle (ATV), airplane, helicopter, or other implement and passed over a field, sprayed onto or injected into the soil, when the granule content is actually needed or germination is sought. The present disclosure also relates to liquid fertilizers of complex chemistry that are not readily available to plants; activation will degrade the nutrient compounds to readily-available forms.
