This paper presents an experimental lab designed for undergraduate students which focuses on soil science and chemistry. Students perform a series of tests to classify soil’s phosphate retaining characteristics, texture, pH, organic matter content, and permeability with the addition of a novel soil amendment, Al Mg biochar. This lab has minimal cost as most chemicals are inexpensive and a soil column is crafted from a used water bottle, filter paper, and masking tape. Students apply their measurements to understand how agriculture plays a role in ocean and watershed health and how soil-testing, soil amendments, and responsible farming practices can minimize agriculture’s footprint. It is important for agriculturally focused students to understand how soil chemistry relates to crop yields, and the importance of responsible agricultural practices. Learning outcomes and student attitudes from this experiment were assessed to evaluate the experiment.
