This document describes pilot B1.4 which takes place in Rostenice, Czech Republic. The pilot aims to develop a platform for mapping crop vigor using earth observation (EO) data to help with variable rate application of fertilizers and pesticides. Key performance indicators include the area of processed EO data, accuracy of delineated management zones, and increased fertilizer use efficiency. The pilot will use data from Landsat and Sentinel satellites to identify crop status, spatial variability, and management zones to help farmers apply inputs more precisely.
