What is the optimal moisture content for harvested grains to ensure quality storage?

1. 10-12%

2. 12-14%

3. 14-16%

4. 16-18%

The correct answer is: 12-14%

The optimal moisture content for harvested grains to ensure quality storage is typically around 12-14%. This range is crucial because moisture levels above this can lead to spoilage, mold growth, and other forms of deterioration that can significantly affect grain quality. Grains that are stored at moisture levels within this range are less likely to experience problems such as insect infestations or fermentation, which can occur when moisture levels are too high. Additionally, storing grains at lower moisture content, such as below 12%, may also be detrimental, as it can result in grain being overly dry and thus more prone to breakage during handling. Therefore, maintaining moisture content in the 12-14% range helps to strike a balance, preserving the quality of the grain while minimizing risks associated with both high and low moisture conditions.
