As I’m sure
you’ve noticed, harvest is rolling right along which means you may be thinking
about storing your grain, at least for a short while. Now I’m sure many of you
are already experts when it comes to storing your grain, but here’s a few tips
for you to consider while you’re driving around in circles in your fields.
The first is
to do an economic analysis of the cost and benefits of storing your grain long
term. Researchers in Australia have found that producers that do a good job of
storing their grain on farm long-term are being rewarded for it. Buyers who
have access to insect-free quality grain that’s been stored on-farm are paying
premiums for this grain throughout the year. While it can be tough to compare
agriculture down under to agriculture in Montana, thinking about the costs and
benefits to storing grain on your farm long-term is an important step in making
grain storage decisions.
It’s also
important to consider the pros and cons of different grain storage methods.
Poly bags are a good option for storage if the grain is stored at the
recommended moisture levels. However, they don’t do well at keeping insects out
of your grain. They’re also not a great barrier from wildlife; wildlife can
puncture the bags and allow moisture into your grain causing spoilage. Grain
piles can be a very effective short-term solution; however, precipitation is
not your friend if this is a strategy you are using. A 1-inch rain can increase
the moisture content of 1 foot of grain by 9 percent. A cone-shaped pile that
is about 25 feet high contains 59,000 bushels of grain. Losing just 1 foot of
grain on the surface is a loss of about 13 percent of the grain, or $58,500 if
the grain value is $6 per bushel. Luckily, 1-inch rains don’t seem to be very
common around here, but it's still something to keep in mind when making your
storage decisions.
Two of the
most obvious things you can do is prepare your bins well and store quality
grain. When preparing your bins, make sure they are nice and clean and there
are no insects present. It also helps to check any under floor areas, as those
are great places for bugs to hide in wait of your tasty grain. If you’re
planning on storing your grain long-term, make sure it’s a good quality, at the
right maturity, and dry enough for long term storage. The drier a grain is, the
longer it will be able to store. Below is a chart to help you determine how long you can store your grain.

Grain needs
to breathe while it’s stored so that it doesn’t spoil. Making sure your bins
are well aerated will make this happen. Properly distributing fines throughout
the bin by using a grain spreader or repetitive coring will help increase
aeration.
It’s also
important to keep an eye on your stored grain throughout the year to make sure
it is still happy. Check your bins about once a month from the top and the side
to look for any evidence of spoilage or insects. A sour smell, grain clumped
together, condensation present on the inside surface of the bin roof, webbing
on the grain surface, or the presence of insect larvae, adult beetles or moths are
all indicators of some sort of problem.
