Gizmodo: Soil Sensors Can Cut Farms’ Water Use By a Quarter During Drought

First, the farmer sticks three wireless, cloud-based sensors in the ground. From there, the sensors analyze soil conditions and suggests an amount of water those crops need. (TechCrunch says the sensors pull from publicly available data of the various soil types that can be found on a field.) Using a mobile app, the farmer views the readings, and the irrigation system is automatically adjusted to distribute just the right amount of water in that particular region of the field.
