FieldSense is a smartphone and tablet application that allows farmers to easily monitor the health of their crops. During the agricultural season, cereal crops, like any other crops, face a number of dangers such as pest attacks, competition with parasitic plants as well as health issues due to lack of nutrients. These lead to large drops in yield and lost revenue. FieldSense will offer farmers weekly updates on the health status of their crops. Farmers can use this information to make informed decisions about how to tackle crop health issues. FieldSense will use Landsat and Sentinel 2 satellite data at its core. FieldSense will use partly processed data supplied by satellite data distributors, which will be further processed into easy to understand color maps describing crop health status.
