Only 11% of our Earth’s land surface has the topsoil considered suitable for producing food. In the United States alone, we are losing at least 3 billion tons of topsoil a year to erosion! Without topsoil, our land becomes a desert and is not capable of producing food. Ready to dig deep to save the soil? Check out the current challenge page for the fall challenge that runs August 15th – November 1st!
Your prototype must address the following needs:
- Address local erosion concerns
- Reduce topsoil erosion
Success will be determined by
- Design, create and test a topsoil erosion simulation model which demonstrates a measurable reduction of topsoil erosion.
- Produce a presentation which shows the topsoil reduction model in use and communicates results.
- Posting a picture or short presentation showcasing the team’s prototype to social media using #PurplePlowChallenge.
