Microbiology senior Madison Goforth arrives at 7am on a chilly fall morning to work with her mentors, Victor and Brandon, and a crew of regular volunteers at Nuestra Tierra garden, managed by the Community Food Bank of Southern Arizona (CFBSA). Madison starts her morning by feeding the chickens and checking their water, then moves to the greenhouse, where she applies a mixture of fish emulsion, kelp, and organic pesticide Bt, to a variety of winter veggie seedlings.
