Farmers are discovering, through the use of drones, how to monitor the health of their fields. Using drones not only spares farmers the expense of hiring a plane for hundreds of dollars an hour but reduces the amount of fuel emissions. Drones equipped with NDVI (Normalized Difference Vegetation Index) can give farmers a heads-up months earlier as to crop yield instead of waiting until harvest time. The devices will help farmers spot potential diseases, weeds and flooding giving them sufficient time to remedy the problem. This will alleviate the need to spray acres and acres of farmland and concentrate on just the areas that need attention. This could be a big step in bringing healthier crops to market due to the reduction of pesticide usage.
