Imagine a tractor that weighs no more than a motorcycle, lightly threading its way through your fields to deliver fertilizer or weed control 24/7 as you relax over coffee. Or a squad of drones locked on to a weed infestation based on a GPS-generated field map, autonomously cruising out to electrostatically spot spray those problem areas.

These technologies and others in the works right now may be coming to your farm if everything falls into place. It takes a lot to get a clever idea from an entrepreneur’s brain into the field: venture capital, testing proof of concept, production, marketing, distribution, to name a few. Successful products make their investors and inventors rich and get their companies listed on the stock exchange or acquired by bigger companies.
