Drones are the next big technological leap for farming. For example:
Oregon State University researchers flew drones this summer over potato fields to monitor for disease. Oregon nurseries have also partnered with researchers to test unmanned technology to count potted trees.
In Florida, farmers and researchers have used small unmanned helicopters equipped with infrared cameras to monitor orange trees for the deadly citrus greening, a bacterial disease that kills the trees. Greening begins at the top of the tree.
The author of the article is clearly focused on farming; there’s nothing about ranching. Imagine the usefulness of drones to finding cattle that are on the open range, or of delivery water or hay to where the cows are waiting for it (for those not from the West, free range cattle do remember where supplies were last dropped in the winter, and will congregate in those spots … often miles from nowhere in particular).
