title: Row crop and cover crop residue spectra from lab spectrometer and spaceborne PRISMA imagery, Maryland, USA.,2006; 2021-2022. U.S. Geological Survey Data Release.

description: This data release contains reflectance spectra of residue (senesced vegetation) for common row crops (corn, soybean, winter wheat) as well as diverse cover crops (cereals, legumes, brassicas) collected in the laboratory using Analytical Spectral Devices (ASD) spectrophotometers (n = 296) and collected in the field using the Itialian Space Agency's spaceborne PRecursore IperSpettrale della Missione Applicativa (PRISMA) imaging spectrometer (n = 65). The data release also contains biochemical trait concentrations (nitrogen, nonstructural carbohydrates, holocellulose, and lignin) from physical samples used to evaluate biochemical trait mapping of cash crop and cover crop residue. Data collection occurred at the USDA-ARS Beltsville Agricultural Research Center in Beltsville, MD, USA, and on the Eastern Shore of MD, USA, between 2006 and 2022.

The data, as well as the processes used to prepare and analyze them, are discussed in detail in a related interpretive summary:
