Quality of stored grain must be maintained through the entire summer period, until stocks can be rotated in the fall. Summer storage is challenging because warm temperatures and high relative humidities put even dry grain at risk for mold and insect activity. Relative humidities in the last two weeks have been very high. The chart below explains why summer aeration can create either continued mold growth or excessive moisture shrink (below 14% moisture corn; 12% moisture soybeans). The horizontal lines are the market standard moistures for corn and soybeans (15% and 13% respectively).
