Abstract
The invention includes an apparatus for protecting plants from frost. A jet urbine engine has an input into which a first liquid and a second liquid are injected into the exhaust stream of the engine. The jet engine also has an exhaust nozzle supplying an aerosol of the first liquid microencapsulated in the second liquid. The aerosol is dispersed about the plants to be protected from frost thereby to form a mist which acts as a protective radiation barrier for the plants. The invention also includes a method for protecting plants from frost.
