Did You Know?
A set of European satellites photographs nearly every field on Earth about every five days in 13 bands of light, several of which human eyes can’t see, and the images are free for anyone to use.
How to Get Started
Precision agriculture is a career you can start practicing with a free map app, a notebook, and a patch of ground, even if the closest farm is miles away. It starts with noticing that no two spots in a yard, garden, or field are exactly alike, and asking what each one needs.
Explore the Basics
With a grown-up, open a free map app and switch to satellite view, then zoom in on farmland anywhere in the country. Look for big green circles, which are fields watered by giant rotating sprinklers, and for the stripes and patterns that tractors leave behind. Pick three fields that look different from each other and guess what might be growing in each one and why they look the way they do.
Try It Out
Plant the same kind of seed in three cups of soil and give each cup a different amount of water every day, like one spoonful, two spoonfuls, and three. Measure the plants with a ruler once a week and write down which amount works best. That is the big idea behind precision agriculture: finding out exactly how much each plant needs instead of giving everything the same.
Join the Community
Ask a parent or caregiver to take you to a farmers market, a county fair, or a pick-your-own farm, and ask a farmer one question about how they decide when to water or feed their crops. Many areas also have free 4-H clubs for kids your age that include gardening and farm projects. Afterward, tell someone at home the most surprising thing you learned.
