Moisture content (m.c., wet basis) and temperature were monitored in two 100 tonne steel silos filled with brown rice during two eight-month storage trials in a sub-tropical climate. One silo was uninsulated. In the first trial measurements indicated considerable m.c. increases at certain locations in the silos, about 7% m.c. at the top surfaces of the rice in both silos and 3% m.c. and 1% m.c. at the north walls of the uninsulated and insulated silos respectively. Bulk aeration and headspace ventilation were applied during the second trial, and m.c. increases were then never more than 2% m.c.
