A minor in Plant and Soil Sciences provides you with knowledge about how plants and soil interact to form the basis of food, fiber, feed, and fuel production. Learn fundamentals on plant biology and soil science relevant to careers in agricultural sciences, natural resources, environmental studies, and more.
The minor in Plant and Soil Science requires 19 hours of course work (not including pre-minor requirements).
