Persistence Data Mining aims to provide advanced precision soil mapping technology using hyperspectral cameras on drones to help farmers optimize fertilizer use. Their technology can identify specific soil nutrients at a precision of one square meter to help farmers create precise prescription maps and variably apply fertilizer only where needed. This has the potential to reduce fertilizer costs by 15%, increase yields by 13%, and protect the environment. They are currently raising $200,000 to complete the proof of concept phase of their technology.
