Abstract
A heated spray system for frost protection and prevention is described. Heated water, such as groundwater, is delivered through a spray system to the area surrounding the irrigated crops, thus increasing the temperature near the crops and preventing frost damage. Surface water is provided, by a drip irrigation line. The crops are protected from excessive irrigation with the addition of protective covers, a protective curtain, and a drainage system. When spraying groundwater for temperature control, the covers, curtain, and drainage system prevent the water from reaching the roots of the crops, and thus prevent the groundwater from damaging the roots due to contaminants and pollutants in the groundwater.
