Calling the Right Shots

Overview

Objectives/Goals The purpose of my project was to find out if there was a difference in vitamin C levels when growing wheatgrass in aquaponics compared with a soil medium. Methods/Materials To complete this project, I used an aquaponics system, soil, wheat berries (to grow the wheatgrass), and starch and iodine to complete the various titration tests. I began my project by growing the wheatgrass in both systems for about two weeks. Then, by using titration, I tested the wheatgrass' vitamin C concentration once a week for a total of four weeks to obtain my final results. Results By averaging the number of iodine drops it took to react to the vitamin C in the wheatgrass solution, I found that there is a fifty-seven percent increase in vitamin C levels when growing wheatgrass in soil. Conclusions/Discussion Even though the wheatgrass grown in aquaponics may have a faster growth rate, and a healthier and greener appearance, the wheatgrass grown in soil had a substantial increase in vitamin C levels. While many people in areas lacking soil turn to aquaponics to grow their fresh fruits and vegetables, they should rethink their choices, and consider sticking with soil to get a more vitamin rich plant.
