What technologies are we talking about?
Onboard computers and GPS-navigators for vehicles that help to avoid overlaps and underlaps when applying seeds, fertilizers, and pesticides. Digital maps of fields based on variable characteristics. Variable rate applications that calculate fertilizer dosage for each individual zone. Drones and satellites help to monitor the field remotely. Wireless weather sensors along with other sensors help to determine temperature, moisture, pressure, and dozens of other field indicators. Computers, smartphones, and applications help to analyze information, maintain documentation and manage the farm efficiently. The list is being updated all the time.
