I didn't get the NRCS drill this year so I had to disc then broadcast and cultipack. There was good soil moisture, but the discing dried it out and of course the seed is all at the surface. My big 100hp diesel tractor is a little much to pull a little 8 foot packer and my little gas farmall is down so I pulled it with my pickup. Four days later the rye in the tire tracks has all germinated in nice 3 inch purple shoots while absolutely nothing has germinated in the cultipacked area. I think its probably more about moisture than the extra soil seed contact. No radishes or oats germinated at all anywhere.
