Grain Bunker Storage Part 1: Site Selection & Positioning

Over the next few months we are going to be taking you through a comprehensive step by step guide to Grain Bunker Storage - from the initial site selection and set-up, through to filling the bunker, sealing it, and the eventual emptying of the bunker when it is time to do so.

Maybe storing in a bunker just isn’t your thing?

Fair enough, but stick with us - not only will we cover bunker storage, but we will have plenty of general storage tips along the way.

And… if things like reduced harvest stress and avoiding the logistic nightmare sound pretty good to you, you may find it worth giving a go!

Maybe you’ve stored in bunkers ump’teen dozen times?

Well, yes, you probably know just about everything there is to know. But you just never know if you might pick up a helpful little hint or tip that will help (we speak to so many people who store grain, and there is always something new that comes up).

So let’s jump in...

Site Selection & Positioning

Planning a grain storage site / facility requires a range of different considerations - often these considerations are the same regardless of the storage being in bunkers or in other storage systems.

The Actual Site

The bunker site should be a well-drained elevated area with dry, hard packed soil where the water table is well below the surface. The surface vegetation will need to be removed ensuring there is no danger of any branches from trees dropping on the tarp. It is advisable to place the closed end of the bunker into the prevailing wind to reduce problems when deploying the cover.

Access

Good access to the site for vehicles and equipment is very important. While not always possible, a continuous loop road around the grain storage bunker is ideal as it requires minimal or little reversing, making loading and out-loading a lot faster and more effective.

If all year around access is required for out-loading, a site placed close to main sealed or hard roads for truck access is essential.

Another consideration is the proximity to the harvest location for effective in-loading during the busy harvest season.

Proximity to Trees, Insects or Bird Havens

Avoiding placing the storage bunker near trees, haystacks or haysheds is a good idea to help avoid pests in the first place, rather than trying to discourage than once they are present. Trees, haysheds and stacks are a haven for insects and birds making migration from nature to the stored grain easier.

The same can be said for water sources, as this also attracts vermin and birds.

Proximity to Resources

Depending on the long term plans for the storage facility it may be advantageous to consider proximity to power sources, electricity and fuel. Equipment such as aeration fans or even a site office may require these amenities in the future.

So this sums up Site Selection and Positioning. Stay tuned for the next edition out next month for all the details about Bunker Dimensions.
