Cargill has teamed with the Nature Conservancy and Nestlé Purina to launch a three-year water project to improve the sustainability of the beef supply chain, the company and the organization said in a joint news release. The project is aimed at reducing the environmental impact of row crop irrigation in Nebraska, as more than 50 percent of water used in U.S. beef production is dedicated to irrigating the row crops that become feed.The Nebraska project enables farmers to install smart weather sensors in crop fields and use Internet of Things (IoT) technology on sprinklers connected to a smart phone app to better manage their water use.
