Many of today's farms are high-tech places. How much do you know about technology on farms?
Farmers today can use robots to help them milk cows more frequently. There are self-driving tractors. GPS helps farmers plan and map crops, guide tractors, and track crop yields. Temperature and moisture sensors allow farmers to know when crops may be overheated or in danger of cold, or when they need irrigation. Drones are used to check on crops, spray chemicals or irrigate, analyze field conditions, and even plant seeds. All of these technologies help farmers be much more efficient, safer, and environmentally sound.
