Crop-Analyzer is a tool for rapid land cover measurements for different crops including wheat, barley, rapeseed, beet, flax and grassland. All measurements are calculated from photos taken in a plot with the app. These measurements group together, depending on the crop, various physiological criteria such as the coverage rate, green biomass, LAI, nitrogen absorbed, tillers per m2, or even eNDVI. The user can, if he wishes, record these measurements on the Crop-Analyser.com portal in order to be able to use them over time at each stage of crop development.
