From ground to air to space: Tillage estimates get tech boost

December 26, 2023

Agri-View: According to national U.S. Department of Agriculture statistics, no-till and conservation tillage are increasing, with more than three-quarters of corn and soybean farmers opting for the practices to reduce soil erosion, maintain soil structure and save on fuel. However those estimates are based primarily on farmer self-reporting and are only compiled once every five years, potentially limiting accuracy.

In a new study funded in part by DTI, University of Illinois Urbana-Champaign scientists led by Kaiyu Guan demonstrate a way to accurately map tilled land in real time by integrating ground, airborne and satellite imagery.
