Average Grain Yields & Storage

[ben.williams151]

I am currently designing a grain store for a university project but the design may be actually considered for the home Farm.

I am calculating the size of the store based on Yields of 7.9 t/ha for Wheat and 6.8 t/ha for Barley (UK averages from AHDB).

My question is, how much tolerance would you consider to be acceptable for change in yields to calculate the storage volume I need? 10% 20% 30%?

Thanks all.

I'd personally work it on the basis of your farms average. Are you looking to build it to store one bulk crop or dividing the store into 2 bays. If you divide you can still fill with one crop and over fill the division if its a concrete divider.

Will probably split into 3 bays more than likely 1/3 Barley. 2/3 Wheat. As more versatile as you said can still use as 1 large crop or split if necessary.

Add 50% to the size you think you need that way you won't have to worry about blocking the front up and then augering the last lot into fill it and the front slope in a dry year when you can't get the height won't run out the door.
Sheds are never big enough!

Thank you very much. Will go for more than I thought then.

Usually never cheaper than now.
When you look back that is!

Can never be too big !

And remember harvesting capacity has historically pretty much doubled every 10 yrs so be sure any handling machinery has plenty of capacity to spare for the future

Thanks allove for your replies. All great stuff to bear in mind.

Are you looking simply at the practicalities of use or the costings that go with it?

Simply the designing the system. Have been instructed to ignore costings for the assigment.

Always factor in plenty of scale for future-proofing.

Think about the physical link with drying facilities and maximising flexibility for storing different combinations of different grades of different varieties of different crops.

It would be much more accurate to use your farm averages, than the ADHB national average (unless of course your family aren't reaching close to the current crop potential, but I assume this is unlikely)

As said above, add in some extra to future proof. This amount though is anyone's guess. However, I would assume this increase is going to be much less than it was between 1975-1990 (see below). I think there is likely to be only very slight increases in the next 10-20 years. Chemicals are unlikely to give much further increase, and varietal development has only given very slight increases in the last 10 years.

In that case I'd go for intake pits to load a continuous flow dryer, with overhead elevators to fill the store.

If it were my choice, I would! But the brief asks to include plans for an on floor drying system not continuous flow unfortunately

Thanks for such a detailed reply, have seen that graph, hence only thinking to account or or around 20% increase as the rise in yields seems to have plataued now.
