is the practice of watering plants less frequently but in targeted manner, and it can force the plant to dig their root systems deeper and be less dependent on watering.Over the years, agricultural research has developed many technological solutions against drought. Giving the increasing risks, however, we need to get better at choosing what works best for each farmer.
Breakthroughs in the past few years have enabled researchers to use low-cost sensors to measure in real-time soil humidity, the hydrological status of the plant, and other parameters. Using drones and other tools, plants can also be scanned directly in the field, harvesting dozens of parameters such as leaf temperatures and leaf-area indexes, which allow researchers to model how plants respond to drought at the leaf or root level.
