Grain Storage Fact Sheet: Dealing with high-moisture grain

Grain at typical harvest temperatures of 25–30°C and moisture content greater than 13–14 per cent provides ideal conditions for mould and insect growth. There are a number of ways to deal with high-moisture grain — the key is to act quickly and effectively.

Key points

  • Deal with high-moisture grain promptly.
  • Monitoring grain moisture and temperature regularly (daily) will enable early detection of mould and insect development.
  • Aeration drying requires airflow rates in excess of 15 litres per second per tonne.
  • Dedicated batch or continuous flow dryers are a more reliable way to dry grain than aeration drying in less-than-ideal ambient conditions.
