How will we feed the world population by the year 2050? The United Nations projects that by 2050 the world population will have risen to 9.7 billion people—more than 2 billion more people than today! To feed everyone, we will need a lot more food, which makes agricultural technology incredibly important. Agricultural technology is the use of science, engineering, and technology to make agriculture (farming) better. This can mean a wide range of things, including preventing plant diseases, gathering data to optimize crop yield (the amount of food you can grow on a piece of land), using resources like water more effectively, or even creating more nutritious versions of a vegetable!
Try one of the projects below to explore some of the solutions farmers, researchers, and engineers are trying around the world. Maybe you'll be working alongside them one day making sure we can feed everyone.

What do plants need to grow? Most of us would answer that they need light, air, water, and soil. But by using a process called hydroponics, you can grow plants without soil! How does it work? Try this project and see for yourself!

Have you ever taken care of a plant? It can be tricky to get it right. You have to remember to water it regularly, and you also have to make sure to give it the right amount of water — not too much or too little. What if technology could help? In this engineering project, you will learn how to automate the entire process of watering a plant. Using a soil moisture sensor and a pump, you will build a circuit that will automatically detect when the soil is too dry, add water, and stop when…

Water is a valuable resource, and water shortages are a serious problem in many parts of the world. The problem can be made worse by people who waste water; for example, by watering a garden or using sprinklers on their lawn (or a farmer taking care of an entire field) when it has rained recently or the soil is already moist. How can you help conserve water and prevent such waste? One way is to build an electronic soil moisture sensor. This project will show you how to build a circuit that…

Have you ever enjoyed eating a tasty sweet potato? They can be served as yummy mashed sweet potatoes with melted butter, turned into golden-brown sweet potato fries, or prepared in many other scrumptious ways. Did you know that you can make a sweet potato grow into a sweet potato plant, and grow several sweet potatoes this way? In this science project, you will grow your own sweet potato plants and investigate what part of the sweet potatoes is needed to grow the plants.

Do you have any great-grandparents who lived through the Great Depression in the United States during the 1930's? If so, they might have stories to tell about terrible dust storms that blackened the skies, from the Midwest to the east coast. Severe drought was a factor in causing this "Dust Bowl" era, but decades of poor farming practices contributed to it, too. In this environmental science fair project, you'll learn about farming methods that help keep dirt from drying up into dust, and help…
