Grain storage issues could flow from rain

Heavy rain across the region is likely to result in broadacre farmers having to deal with grain going into storage with high moisture content.
High moisture stored grain can lead to mould and insect growth, which has led to storage experts advising growers to take prompt action to avoid damage.
Grain-storage specialist Peter Botta said monitoring grain moisture and temperature daily would enable early detection of mould and insect development.
“Grain at typical harvest temperatures of 25 to 30 degrees and moisture content greater than 13 to 14 percent provides ideal conditions for mould as well as insects,” he said.
“Although many growers do not have the equipment and infrastructure in place for drying grain, there are some other measures they can take to reduce the risk of grain being damaged in storage.”
Grain over the standard safe storage moisture content of 12.5 percent can be dealt with by:
• Blending – mixing high-moisture grain with low-moisture grain, then aerating.
• Aeration cooling – grain of moderate moisture, up to 15 percent moisture content, can be held for a short term under aeration cooling until drying equipment is available.
• Aeration drying – large volumes of air forces a drying front through the grain in storage and slowly removes moisture. Supplementary heating can be added. Aeration drying requires airflow rates in excess of 15 litres per second per tonne.
• Continuous flow drying – grain is transferred through a dryer, which uses a high volume of heated air to pass through the continual flow of grain.
• Batch drying – usually a transportable trailer drying 10 to 20 tonnes of grain at a time with a high volume of heated air, which passes through the grain and out perforated walls.
