If tablets are used on a tray, you must create 30 cm of airspace above the tray of tablets to avoid the development of explosive concentrations of gas. Allow 10 days for the gas to release and full circulation to occur. Open the rolled edges and let the remaining gas escape. Remove the tarpaulin and allow three days of ventilation before delivery. If the tarpaulin is large enough it may be possible to dump the grain in the middle and roll the edges together on top of the pile.
White silos Painting the silo white after installation on the pad is a useful management tool.
Aeration Aerated silos are fitted with fans that pass controlled amounts of air through the grain. When aerated correctly, the grain is cooled and the grain temperature and moisture are equalised throughout the silo. Fans are run for extended periods during the first few days of storage. An average of 12 hours using the coolest and driest air of the day is common. This removes harvest heat and evens out temperature and moisture, avoiding hot spots and moisture damage.
