Moisture content and fluctuating temperatures are one of the biggest challenges farmers face when it comes to safely storing their grains. In order to make sure stored grain doesn’t spoil during the warmer months, farmers must frequently analyze samples of their stored grain to make sure it’s able to handle the heat. The ideal temperature for storing grain and preventing mold and insect growth is anywhere between 25°F and 60°F, but these storage temperatures can be hard to maintain when outside temperatures are consistently over 80°F during the summer. Freshly harvested grain is particularly challenging to store because of its naturally higher moisture content and temperature. During storage, the grain changes both physically and chemically, and this warmer, wetter grain will respire in its storage bins, producing additional heat and moisture. Consequently, that additional heat and moisture generated during storage leads to hotspot development, mold growth, and mycotoxin development – all of which lead to grain spoilage.
