Not mentioned, but important. Cold temperature germination test your seed. On a low scoring seed, you are more likely to get erratic delays in germination if planting into 40-50f soil. Worst case this translates into an overall lower stand as well. Maybe unscientific to the lab standards, but taking 2 samples, soaking at 40 in farm soil, then returning to greenhouse led to 90% emergence for one sample and 50% for the other on day 5. The interesting thing is the lower scored sample didn't have another emerge for 2 days with a final 70% stand. OR wait until the soil is 65 and you eliminate this problem. Good luck.
If you can go slow...go slow...the first man to 400bu twenty years ago did it with a finger planter...but he would put a can of coke on the planter...if the can fell off...he would slow down.
