Increase crop yields
Plants perform poorly under stress (too much or too little water), so optimizing irrigation schedules can not only lead to bigger yields but a cost savings in less water waste and a lower water bill.
In order to irrigate a particular crop at the optimum level, a farmer would install several probes in one location. One probe would be placed just below the surface of the soil, one in the root zone, and one below the root zone. When water is applied to this soil, these sensors reveal data about how quickly the water penetrates down through the soil. The farmer can adjust his irrigation schedule accordingly. Furthermore, by seeing if any of the water is making it down below the root zone, the farmer can water less, saving money.
