No need to adust seeding rate
There most likely is no need to adjust corn seeding rate. "Mudding-in" is less than ideal, but a couple thousand extra seeds per acre most likely will not improve the odds of good emergence. (There is some evidence that in soybeans, increasing seeding rate by about 120,000 to about 200,000 seeds per acre could improve emergence in crusted soils.
But that is a different scenario.) If the conditions for corn emergence are poor, then an extra seeding rate probably will not help.
Be careful with vertical tillage and other implements used to "dry out" the soil. They may dry out the upper couple of inches, which will help with seed placement, but they also could cause compaction at the tillage depth/point of tool-soil contact.
As such, seeding could go very well, but the compaction just beneath the seed could hurt root development later. If mud is sticking to the units, then the compaction risk is real.
Any curved blade run at an angle (i.e. a disk) is at a higher risk for causing shear compaction at the blade tip than a unit that runs straight (or wavy) blades straight up and down and in line.
All implements run some risk of causing compaction. The key issues are the amount of down-pressure developed by the implement and the number of blades transmitting that pressure into the soil.
Minimize down-pressure by setting the implement to maintain the desired operating depth. Do not operate an implement ‘wheels up’, with the full weight of the implement riding the blades into the soil deeper than needed.
Finally, planting a wet field is done at your own risk. There are some very good logistical reasons as to why to mud-in fields. There are no good agronomic reasons to do so.
You may beat the odds and get a great stand of corn with limited to no problems from mudding-in corn. But, the odds favor problems occurring later in the season.
Be sure to scout these fields early to identify problems. Such problems could change how you manage the fields (and market your crops) later in the season.
