Internet of Things is taking Precision Irrigation to the Next Level

Precision irrigation follows a methodology of taking into account spatial and temporal variability in water stress. In this way, precision farming technologies enable farmers to delineate management and actuation zones for irrigation according to variations in crop and soil characteristics, with the objective of optimizing blue water use. The concept is now being enhanced by data-enabled technologies: smart irrigation systems monitor crop and soil water needs in real time based on a network of wireless captors, storing and processing data in cloud applications. At the end of the cycle, the underlying information feeds into irrigation protocols, defining when and where to spray water, and in what amount. For example, combining soil/crop data with weather forecasts can delay irrigation if a storm is looming.
