My brother’s Father-in-Law is a 4th generation farmer. MBA and MS in Agricultural Economics. The tech setup these guys have is amazing. GPS guided tractors, satellite field imagery showing where fertilizer is best used, QR code tagged livestock, the whole shebang.
Farmers to survive have gone really high tech for both the science and the business sophistication. If not, they are put out of business by the corporate farmers such as Cargill and ADM.
On YouTube, look up the channel for Millennial Farmer. It's interesting.:.
