Question

Quizplus · Accepted Answer

Sprinklers work best when the air is fairly humid because the water droplets will evaporate and absorb heat from the surrounding environment, preventing the temperature from dropping further. If the air is too dry, the water will evaporate too quickly and not have enough time to absorb enough heat to prevent crop damage. If the surface air temperature remains below freezing for a few hours, it may be too late to prevent crop damage through the use of sprinklers. Allowing the ice to cool to -15°C is not a factor in the effectiveness of using sprinklers for crop protection.
