The Noisy Truth: Plants Cry Out for Help When Stressed

A new study from Tel Aviv University found that plants emit specific sounds when under stress, which can be detected by ultrasonic microphones. The sounds are too high for humans to hear, but can be heard by animals such as bats, mice, and insects. The study found that stressed plants emit dozens of sounds every hour, while unstressed plants emit less than one sound per hour. This discovery could prove beneficial in the agriculture industry, as more precise irrigation can save up to 50% of water expenditure and increase yield.
