The Importance of Moisture Content of Grains for Storage

Feb 15, 2024

As a key player in the agricultural industry, TSGC Inc. understands the significance of moisture content in grains when it comes to proper storage. With our expertise in Farm Equipment Repair and Farming Equipment, we aim to provide you with the necessary knowledge and tools to ensure the success of your grain storage operations.

The Role of Moisture Content

Moisture content is a critical factor that can greatly affect the quality and longevity of stored grains. It refers to the amount of water present in the grains and is usually measured as a percentage of the grain's weight. Understanding the ideal moisture content for various types of grains is essential for effective storage, preventing spoilage, and maximizing profits.

Effects of High Moisture Content

Grains with high moisture content are more prone to spoilage and the growth of molds, fungi, and bacteria. These microorganisms thrive in moist environments and can result in issues such as grain heating, reduced nutritional value, and even the production of harmful mycotoxins. The presence of mycotoxins not only affects the quality of the stored grains but also poses significant health hazards to animals and humans when consumed.

Moreover, high moisture content can lead to clumping and caking of the grains, making it difficult to handle and store them properly. This can result in additional processing costs and potential damage to equipment during grain handling.

Effects of Low Moisture Content

On the other hand, grains with low moisture content are more susceptible to breakage and increased shrinkage during storage. Dry grains can lose moisture and weight, decreasing their value and reducing overall profitability. Inadequate moisture content can also negatively impact grain quality, affecting factors such as color, flavor, and cooking properties.

Furthermore, low moisture content can lead to increased dustiness and the generation of static electricity. These factors can make grain handling and transportation more challenging, resulting in potential losses and safety hazards.

Optimal Moisture Content for Different Grains

The ideal moisture content for grains varies depending on the type of grain, environmental factors, and intended storage duration. It is crucial to be aware of these specific requirements to ensure optimal storage conditions and prevent spoilage.

Corn (Maize)

For corn, the generally recommended moisture content for short-term storage, such as on-farm bins, ranges from 13% to 15%. However, for long-term storage, such as in silos, moisture content should be reduced to around 12% to 14% to prevent deterioration.


Wheat should ideally have a moisture content between 12% and 14% for safe and efficient storage. To safeguard its quality during long-term storage, it is advisable to lower the moisture content to about 11% for winter wheat and 13% for spring wheat.


Rice requires precise moisture control due to its high susceptibility to insect damage and fungal growth. The moisture content for rice should be within the range of 12% to 14% to maintain its quality and prevent spoilage.
