Permalink Variable Rate Irrigation Improves Efficiency

In a quest to improve the sustainability of fresh water use in agriculture while optimizing crop production, University of Georgia researchers have been working with Variable Rate Irrigation, reports The Red & Black. The team maps crop fields to determine how much water each part of the field needs. Drones with thermal imaging combine with soil moisture sensors to provide data that helps the team develop a prescription for each part of the field. Variable Rate Irrigation can be used on a center pivot or on a lateral-move irrigation system to deliver just the right amount of water in each section of the field. The system will be field-tested in a commercial setting next year.
