As agricultural production expands into higher-latitude and continental-climate regions, the challenge of maintaining raw grain storage quality through harsh winters has become one of the most pressing technical issues facing the global grain industry. From the vast agricultural plains of Central Asia and Russia to the northeastern grain belts of China, operators responsible for raw grain storage must contend with extreme temperature swings, heavy snowfall, ground frost, and freeze-thaw cycles that place enormous stress on storage systems and grain condition alike. Understanding how these conditions affect raw grain storage—and what operational practices help mitigate the risks—has never been more important.
