The American Forage and Grassland Council has a forage management essay competition for youth. There are categories of under 14 years of age and 14 to 18 years of age. Age categories are as of January 1, 2019.
I encourage you to review the information about the competition at the link below.
There likely are some freshmen at Purdue that meet the age requirement. Within 4-H and high school vocational agriculture classes this is a great opportunity, too.
Please share the information to interested groups or individuals.
