A tiny chip helps farmers measure thirsty soil

Story three is about technology on the farm. A low-power sensor chip can help farmers decide when crops need water. The report calls the soil 'thirsty,' which is a friendly way to say the soil may be dry and plants might need more moisture. We do not know the exact crop, farm location, or how widely the chip is being used, so we’ll describe it carefully: this kind of tool can give farmers better information. Instead of only guessing by looking at the top of the ground, a sensor may help measure moisture where plant roots are growing. That matters because water is precious. Too little water can stress plants. Too much water can waste resources and may not help the crop. A small chip that uses very little power could be useful because farms can cover large areas, and tools may need to work for a long time. This story shows how tiny technology can help answer a very practical question: Do these plants need a drink today?
