Did you know that there is more than one type of corn harvesting going on right now?
On our farm we grow and harvest corn that will later be fed to our cows as a portion of their overall diet called High Moisture Corn or HMC. Unlike shell corn, which is harvested and stored in grain bins and needs to be dry to prevent it from spoiling, high moisture corn is fermented and stored in silos or other airtight storage options.
Before harvest ever starts, there is a lot of prep work to do, we must get the silos ready to hold the corn.
Once the silos are ready to go, we head to the fields and start harvesting our corn. Here is the quick and skinny on how it is harvested and stored. You may want to turn your volume down on the computer, it’s hard to get video of large equipment without large noise.
This is high moisture corn. It looks like shell corn but it has (surprise!) a higher moisture content. If this was shell corn, Hubs wouldn’t be able to easily crush the kernels with his fingers.
We don’t just randomly guess at how much moisture is in our corn, not only does the combine have a moisture sensor, we have a tester that reads the moisture content of our corn. Ideally high moisture corn will be 25-30% moisture. This field was 23.3% so slightly on the dry side but not too bad.
The combine harvests the corn and then puts it into a bin that we can haul back to the farm. We usually have two people on tractors running bins of corn back and forth between the field and the farm so that the combine can keep rolling.
After we haul the corn back to the farm we put it in the silos. On our farm we add an additional step before this happens by running it through a hammer mill that crushes the kernels. This makes the corn easier for our cows to break down and utilize the energy when they eat it. Some farms use a hammer mill when they pull the corn out of the silo to feed it.
The funny thing about using something that pulverizes the corn before flinging it up the silo is that we end up with corn flour everywhere!
Hubs remembers his mom making pancakes out of this flour. Of course I meant to grab a ziplock bag full but I forgot and then it rained. Corn flour paste probably doesn’t make very good pancakes.
This last year we planted about 180 of our 300 acres with corn, most of that was harvested for corn silage which is the entire corn plant, not just the kernels. This year we harvested about 85 acres of that 180 acres for high moisture corn. The 85 acres gave us enough to last us about 15-16 months according to Hub’s math. We were going to include more exact calculations but I can’t math and trying to figure it out exactly was making us fight.
Now that our corn silage is done, our soybeans are harvested and taken to the coop in town and high moisture corn harvest is all done, we can feel the relief of knowing that we have enough feed for our cows for the next year. But the work is far from done. We still have fall tillage to do and lots of things to get ready on the farm before winter sets in.
