Radiation frost occurs on clear, windless nights when the earth's heat radiates upward through an open sky, causing temperatures to drop dramatically in low-lying areas where cold air pools. Effective frost protection requires strategically placing heat sources (such as smudge pots, oil burners, or straw heaps) in the lowest areas where cold air naturally settles, creating a protective thermal layer that prevents temperatures from dropping below critical thresholds for crops and livestock.
