This quarter we have collected and analyzed samples collected at 30 DAP using vial collection technique developed during the previous growing season. Initial correlation to moisture readings were performed. It should be noted that for the 30 DAP moisture readings, the probe depths were measured at 8 and 16cm. The probe depths were changed to 4 and 8 cm for the 50, 70, and 90 DAP readings. During this time we have also explored the use of specialized absorbent material that coats a magnetic stir bar, Twisters. This exploration includes the absorption of VOCs onto the bar and developing special GC/MS recipes for sample injection with the help with Dr. Dimandja at the FDA.
