Fall Harvest – Corn or Soybeans First?

On our farm, we raise corn and soybeans. Both crops are harvested in the fall.  Did you know that in some areas corn is harvested first and other areas soybeans are harvested first?

Corn being harvested. The corn is “fed” into the header on the combine where the corn kernals separate from the leaves and stalks. The leaves and stalks become compost for the soil.

On our farm in Northeast Kansas, we always start harvesting corn first.  Our corn is ready anytime from late August to mid-September depending on when the corn was planted and the weather Mother Nature provided throughout the growing season.  Some years we can be completely done harvesting corn prior to starting soybeans.  Other years, we’ll harvest corn for a few weeks then switch over to soybeans.

Once soybeans have lost their leaves, they need to be harvested ASAP. As the soybean pod dries down, the beans can “shatter” by splitting the pods open, and allowing the individual soybeans to fall to the ground. The soybeans can’t be picked up off the ground – they literally fall on top of the ground and there isn’t a machine that’s able to pick them up.

THIS is where we have a challenge this year.  The corn stalk quality is not very good this year which means that the corn can blow over or fall down easily the longer it’s in the field.  Heaven forbid a big wind storm or rain come through and be further detrimental to the corn falling over.

Did you know that areas that are north of us harvest their soybeans before corn?  Each area grows varieties that work well in their area, and the ones in the north mature earlier. Partially this is because soybeans are light dependent, and the days are shorter farther north.  Likewise for our area in Kansas, the days are getting shorter, and the soybean plants are all maturing quickly.  The northern half of Nebraska and north into the Dakotas and Minnesota harvest soybeans first then switch to corn.  The southern part of Nebraska and south into Kansas and Missouri harvest corn first then switch to soybeans.  You could draw a line across the United States – north would harvest soybeans first and south would generally harvest corn first.

So what are we going to do on our farm?  We will switch from corn to soybean harvest as soon as the soybeans are ready.  We know that the longer mature soybeans stay in the field the more will shatter and the less there will be to harvest.  Hopefully, the corn will continue to stand. A few years ago when the corn was down, we invested in a corn reel for the combine which makes it easier to pick up corn that’s fallen over.

Like many other farmers, we will continue to work long hours to bring the harvest in.  It can be a stressful time of year, but it’s also very rewarding to bring in the harvest.  We grow crops, now we’re harvesting.
