Interseeding 60-Inch Corn for Improved ROI - Farminar

- In 2019, @eric18miller began his own on-farm research project planting 60” corn with a cover crop mix seeded in between the rows in June. He prefers seeding cover crops at this time of year because it fits into his schedule. The wide corn rows result in ample cover crop growth by the fall, which in turn presents opportunities for grazing. Eric says the big plus of this system is his reduced use of inputs like residual herbicides, insecticides, fungicides and fertilizer.
Eric Miller has been farming in northeast Iowa since 2009. His first years in farming were good as crop prices were high, but after price drops in recent years, he found he was struggling financially and began trying to figure out how to improve his bottom line.

Loved the 2 rainbows in picture s
What is your tillage program for planting corn? How do you get cover established in standing corn if you have heavy mat from dedicated cover?
Late to the party. But in regards to spraying, is Eric able to run wider tires on his sprayer in order to help reduce compaction in the field as well?
So I've seen a lot of 60 inch corn research done that looks positive for sure. However, everything I see is done for whole corn. Has anyone done/seen any research when planting corn for forage/silage?
Silage is harvested early enough to just plant after harvest
How do you get the twin rows to perfectly stager the plants so the twin rows don't have corn plants side by side or doesn't it matter?
like he said, the meter units on his planter can be timed to stagger plant. It takes a little time to get everything timed, but essentially, you set one row to drop while the other is halfway around to dropping the seed (it depends on your metering units how you set them to stagger plant). Most of this equipment is ground driven, electronically driven, or hydraulic driven, so the metering mechanisms move together (or in this case, the entire unit is lifted and lowered together, so everything starts and stops together)
Ground driven seeders are what I have most experience with, so here goes:
The planter is carried by 2-5 large tires, those wheels are connected to a central drive shaft with roller chains. The driveshaft turns, and there are sprockets for each of the row units pinned to the shaft. A roller chain goes from the driveshaft then, down to the metering unit on the seed hopper. By changing sprocket size on your row unit, you can change the density of planting (like where his corn is spaced further than his interrow covers), and by manually setting the twin row units to be staggered. As long as nothing in the drive line breaks (and allows things to not spin or spin freely), everything stays in time.
If you want to see a very simple version of a seed meter, look at seed plates for an earthway garden seeder or a seed roller for a Jang seeder.
For contract grazing after harvest, did you have existing fences? Or did you or the grazer put up temporary electric fences?
Grazer put up temp he said...
What would happen if you went back to the old 38" rows and maintained the plant population? Please follow up - what was the difference in yield between the 30 and 60 inch rows?
LOL:) I still got my 40 inch row planter in the barn. Most guys down South planted 40 inch rows for a LONG time because if you farmed cotton it wasn't until the 90's they had a cotton picker capable of picking 30 inch rows. Some guys had a corn planter set up for 30's and a cotton planter on 38-40's, but that basically meant you had to have 2 sets of equipment, particularly if you were farming on beds, so most guys didn't.
I'd be curious to see what the interseeded stuff would do on 40 inch rows. 40's have a VERY difficult time every closing the canopy, even in corn and grain sorghum, or soybeans. Cotton is a little "bushier" than most soybeans and CAN close a 40 inch row middle, leave pretty much touching, BUT it's usually REALLY late in the season. It'd be interesting to see what it'd do. Later! OL J R :)
I’d say it’s harder to deal with finding a 40” corn head. I think 40” would be ideal, but 30” equipment works on 60”.
I did 60” twins. It didn’t lose after factoring in the beef gain. About a wash really. Our equipment changed, we went down to 20” corn and soybeans. Being organic and not using herbicide, spring covers that get roller crimped, and quicker closing of the rows are the main foundation of my weed control.
Apa saja tanaman cover crop
They are plants grasses and legumes planted between cash crop seasons to keep the soil covered so it is less likely to blow away, erode or dry out.
You don't harvest them, when they die they compost into the soil.
Often using nitrogen fixing plants to bring nutrition into the soil.
Sometimes used for feeding livestock on.
