Crop performance is estimated by multispectral satellite images. One of the most popular methods is the measurement of the vegetative index NDVI. The field is divided into sections with different indexes, which allows you to see plant performance even in remote areas. On the basis of the vegetation indexes, digital maps for the differentiated application of fertilizers and pesticides are created.
Usually, analyzing a field with satellite images is a paid service. We have created the scouting app
that allows the monitoring of crop performance for free.
