Land Minds: History repeating itself?
Originally published in the November 13, 2009, print edition.
— “Harvest corn in the spring?” was the headline above a story in the November 1987 issue of Farm Show. I had told Harold Johnson, a long-time farm editor friend, and at that time editor-publisher of Farm Show, about my venture in farming the year prior. The following is his/my story from that issue.
If you’ve ever toyed with the idea of letting corn stand in the field over winter to let Mother Nature dry and store it, you’ll get a lot of encouragement from Richard Hagen, Olivia, an 80-acre hobby farmer and ridge-till enthusiast.
A year ago this fall, his corn crop was high in moisture. So instead of going through the hassle and expense of running it through a dryer, into storage and then back out again in the spring for delivery to the local elevator, he decided to let the crop stand in the field over winter and then harvest, hopefully in early April.
Fortunately, last winter was one of the mildest ever in Minnesota and Hagen’s corn crop “survived” with excellent standability and ear retention — despite the fact that he’d planted about one-third of the acreage to 90-day maturity seed.
Thanks to an early spring, he was able to harvest the crop April 1 (no pun intended) when temperatures were in the low-20s and there was still enough frost to carry the combine.
Average yield was 133.3 bushels per acre. Moisture content averaged 15 percent and field loss was only 7 percent. Adding up the pluses and minuses, Hagen figures he netted an extra $30 per acre by letting the crop over-winter in the field. Here’s how it penciled out:
On the plus side, he saved $33.33 per acre in storage costs (he doesn’t have grain storage facilities) figured at 25 cents per bushel and $24.66 per acre in drying costs (18 cents per bushel). On the minus side, since standing corn doesn’t quality for Commodity Credit Corp. loan, the opportunity cost of lost interest was $11.66 (133.3 bushels times $1.75 loan rate times 10 percent interest for six months). The 7 percent field loss translated to a cost of $16.45 (9.4 bushels at the $1.75 per bushel loan rate).
The final tally: $29.88 or right at $30 per acre net advantage for spring over fall harvested corn.
Twenty-two years later, in 2009, would I recommend doing this again? Only if fall harvest wasn’t doable because of weather or “whatever” conditions. Lots of risks associated with leaving your corn until spring even though today’s hybrids seem to have far stronger stalks, and ear droppage really isn’t much an issue any more.
I recall drifting snow did pretty well clobber the eight rows of corn on the west side of the field (rows ran north and south). Also remember that I was a ridge tiller, which meant there was no fall or spring tillage. With my corn going on last year’s soybean ridges, I did a fall fertilizer application about six inches deep right on the soybean ridges for next year’s corn.
My only request is that if any readers do indeed leave some corn until next spring (for whatever the reason), let me know the results. The tremendous crunch of getting harvest, tillage and fall fertilization done this fall is likely creating a bit more gray hair for Minnesota farmers.

Residual value — How much is field trash worth?
Maybe we need to think more positively about trash. We’re talking trash as residue left on fields after harvest, or any time as a matter of fact. Does it have value?

Back Roads: Quiet on the set; eat!: Ding-Dong Café, Sauk Centre
When the trains pulled up their tracks, many of the businesses along them closed their doors. The Ding-Dong Café, in Sauk Centre, covered its walls in train memorabilia and kept right on serving.

Better machinery makes continuous corn work
Equipment industry has responded to the movement toward more conservation tillage.

No-till benefits add up with diesel fuel savings
Less field time, virtually zero erosion, improved soil quality and as good or better yields are four solid reasons for considering no-till (including strip till and ridge till) farming.

Opinions differ on if, when rolling fields is right
The question keeps surfacing: Is rolling my fields sensible? And, if so, when do I roll?

Land Minds: Bumps on the road to liberty
I sense we are becoming a nation of entitlements. And in the process of this slide into socialism, I sense that we can no longer rely upon the “political process” to reverse this uncomfortable transition. “What’s in it for me?” seems to be the new mantra now embraced by many people including our elected officials.

Farm and Food File: USDA-DOJ seed competition workshop better work
Holding the “first joint Department of Justice/USDA workshops ever on competition and regulatory issues” in Iowa, the heart of corn and soybean country, just weeks before every seed-buying farmer in America will be pedal-to-the-metal planting this year’s crop is bigger than Daytona, bigger than the All Star game and bigger than the Super Bowl.

Cover story: The legacy of Wendelin Grimm and his 'everlasting clover'
Grimm was the farmer who developed winter-hardy alfalfa, which after his death became known as Grimm alfalfa. It helped make Carver County a premier dairy belt, and became the basis of the alfalfa used throughout Minnesota, and across wintry North America.

Minnesota Machinery Museum breathes life into past
After using grant funds to make necessary improvements, the Yellow Medicine Agricultural and Transportation Museum opened Aug. 9, 1980, during the Pioneer Power Threshing Show. Under the guidance of Minnesota Historical Society Field Service Coordinator David Nystuen, the six-acre site found new life, and soon the name was changed to the Minnesota Machinery Museum.
