Grain storage can create value long after harvest.

Having grain in your own system gives you more control over when you market it and more flexibility to respond as basis, futures and freight conditions change throughout the year.

Our latest article looks at how on-farm storage can give you more marketing options beyond harvest.


Learn how grain storage can create marketing flexibility through basis improvement, futures carry, and better timing.

If you're using a dryer you need to hear this. 👇

Our Custom Dryer Service team is building this new Meyer tower dryer in Gettysburg, South Dakota, and there's some pretty interesting engineering hidden inside that uniform-looking tower.

On a MEYER ENERGY MISER® Tower Dryer, the grain column isn't actually the same width from top to bottom. The upper 22% uses a 10-inch grain column, where the wettest grain first enters the drying process. That narrower column allows more airflow through the grain.

The remainder increases to a 12-inch grain column, allowing greater saturation of the heated air as it passes through the grain.

It's a relatively small change in dimension with a very intentional purpose: the variable-width design improves both fuel efficiency and drying capacity.

Pretty cool engineering from Brock Grain Systems, a Division of CTB, Inc. and another great-looking build by our Custom Dryer Service crew.
