Ready to plant?

Yesterday I saw 2 or 3 planters out of the shed.  Are these guys ready to plant?  I hope not, although a few years ago a coating technology was available that would allow corn to be planted very early and germinate 3 to 4 weeks later.  I suppose they were out just to make sure they are ready to plant.  Precision Planting has a checklist of things to do before planting.  I cannot write a checklist this well, so click on the link.  Be sure and check out the video too.  If the weather holds, April 1 will come around fast.  I suspect some will push that date a little bit too if soils are warm.
