Ditto this...
Additionally, you're not planting for optimal crop harvest, you're planting to attract deer.
I have open fields ranging from 15 acres to 1/2 acre.
About five fields range from the 1/4 acre to three acres.
I plant only those smaller fields for winter deer feeding. Deer like the smaller closed in fields much better, they feel more protected and safe. I also have a couple small strips in the woods about 50-60 yards long by 15-20 yards wide that I plant, and those smaller spots are great for bow hunting, since bow hunting does require a closer shot and this closed in open planted strip is a deer haven.
We lime each year with planting, and I've also limed in the spring. Since we plant in September, by the time Dec-Jan comes around with some good rain, the lime is in the soil and doing it's job.
My process:
Some years in late December, I've disced a few edges of fields and spread additional rape/turnips/beets since those are long gone by then.
These two images are one week after planting with only a light rain. They don't look like much right now, but we're getting downpours today and tomorrow, so in a week, this place will be lush.
The first is about a half acre planted in a larger two acre opening.
The second is a small strip in the woods surrounded by a creek and abundant acorns.
