Boosting yield at harvest is the goal of Ceres Imaging’s Cumulative Stress Index. Remote sensing scientist and crop consultant Kirk Stueve explains the company flies planes over farms and takes photos, using custom built-sensors and special analytics to determine stress points in the field. That data is reported to customers throughout the growing season. At the end of the season, the company combines results for a Cumulative Stress Index. The technology could be useful for managing nitrogen in corn. “We’re looking at using this technology to detect when you still have a chance to respond,” says Stueve. “If you don’t see any of that early signal, it can help you save on input costs.” The Cumulative Stress Index will be available for the upcoming growing season.
