Prevent Spoilage with Effective Grain Storage Tactics
As spring arrives, managing grain storage becomes critical due to rising temperatures, warns Ken Hellevang, an expert from North Dakota State University.
Solar heat significantly increases bin wall temperatures, particularly on the south side during spring, leading to potential grain spoilage. A mere 10-degree rise can halve the grain's viable storage time, emphasizing the importance of temperature control.
Hellevang recommends using aeration fans to maintain grain temperatures below 40 degrees as long as possible in the season. This practice helps mitigate the heat from solar gains on both the bin walls and roof, which are prime contributors to spoilage.
Ensuring bin vents are clear of frost and ice is also crucial, especially when fans operate in near-freezing conditions.
For effective grain management, regular monitoring is key. Grain temperatures should be checked bi-weekly, with any rise indicating potential issues.
Inspecting for insects and checking moisture levels is also vital, ensuring the grain remains at optimal dryness levels for safe storage.
Various grains have specific moisture content targets for safe summer storage: corn at 13% to 14%, soybeans at 11% to 12%, and wheat at 13%.
As outdoor temperatures climb, stored grain in alternative structures like grain bags must also be dry, as these too will reflect external temperature changes.
Hellevang stresses safety in grain handling, reminding everyone to adhere to best safety practices to avoid accidents.
With these strategies, grain can be effectively managed through the challenging spring and early summer periods, preventing loss and maintaining quality.
