Potential of Sentinel-2 Satellite Images for Monitoring Green Waste Compost and Manure Amendments in Temperate Cropland

Increasing attention has been placed on the agroecological impact of applying exogenous organic matter (EOM) amendments, such as green waste compost (GWC) and livestock manure, to agricultural landscapes. However, monitoring frequency locality this practice poses a major challenge, these events are typically unreported. The purpose study is evaluate utility Sentinel-2 imagery for detection EOM amendments. Specifically, we investigated spectral shift resulting from GWC manure application at two spatial scales, satellite proximal. At scale, multispectral image pairs were analyzed before after six cultivated fields in Versailles Plain, France. proximal multi-temporal field measurements taken experimental plots consisting 14 total treatments: variety, amendment quantity (15, 30 60 t.ha−1) tillage. images showed significant differences application. Exogenous Organic Matter Indices (EOMI) developed separative performance. best performing index was EOMI2, using B4 B12 bands. simulated reflectance spectra, which created measurements, successfully monitored all treatments three days, except buried rate 15 t.ha−1.
