These days, plants and trees are under a lot of stress: air pollution, deforestation, drought, flooding, etc. However, what has recently caught the attention of plant scientists is another danger threatening trees: air dryness. According to a report by Agence France-Presse, a lack of moisture in the air can be even more detrimental to trees than dry soil. In a recent study published in the prestigious scientific journal Nature, botanists from Indiana University in the United States have shown that air dryness has a greater impact on trees and the health of their crops than soil dryness. In this research, scientists recreated models of hot, dry air similar to what trees experience during droughts. The lead author of this study, Kimberly Novick from the Indiana University School of Environment, states, 'There are many uncertainties regarding our ability to predict future carbon absorption patterns by plants.' According to Novick, many of these uncertainties stem from our lack of understanding of ecosystem responses to drought. She says, 'Our work shows that determining how plants respond to changes in atmospheric moisture can be one way to reduce this uncertainty.' According to Nature World News, this research demonstrates how, during droughts, dry soil is unable to provide the necessary moisture to plants. Meanwhile, dry air, or air with low humidity, absorbs moisture from the plant. Plants naturally have a defense system that resists moisture absorption by the air. Small pores in the leaves and trunks of trees can close during droughts to prevent moisture loss from the plant. However, closing these pores simultaneously reduces the amount of carbon dioxide the plant can absorb from the air. Absorbing carbon dioxide and releasing oxygen is one of the essential roles of plants in maintaining the environment. The ability to accurately predict climatic changes can lead to necessary actions for preserving trees. This research indicates that simply storing water for lands during droughts is not enough for the survival of plants, and new measures must be taken, especially as global warming increases and prolonged droughts become more widespread around the world.
Air Dryness is as Harmful to Plants as Soil Dryness
Recent research highlights that air dryness poses a significant threat to plant health, potentially more so than soil dryness. Scientists from Indiana University emphasize the need for better understanding of ecosystem responses to drought to improve predictions of carbon absorption by plants. This is crucial as global warming intensifies and droughts become more common.
