Research for precision watering of fruit trees

Advanced technology can help farmers get to the root of a growing problem -- overwatering in an era of increasing drought and water scarcity. A new UC Riverside system can map soil moisture tree by tree, so growers water only where and when it's needed. 

This system, detailed in the journal Computer and Electronics in Agriculture, was led by the research group of Elia Scudiero, associate professor of precision agriculture and the Director of UCR's Center for Agriculture, Food, and the Environment (CAFE). 

Water management is one of the biggest challenges facing agriculture in California and other dry regions. Currently, some growers rely on soil moisture sensors buried in the ground to determine when to irrigate. These sensors are expensive and typically installed in only a few locations, leaving growers to guess how conditions vary across hundreds or thousands of trees.
