I just posted this pic on one of the other threads here. I label it "A Perfect Planting Day", and I literally think that. All of my 400+ acres of rolling row crop land was seeded down this way, following both soybeans and untouched cornstalks, usually planted in early to mid-March. These are Deere 8300 regular old grain drills. Prefer to do it through a fresh 3-4" snow if I can, onto frozen ground. Easy to see your drill mark that way, and not have any skips. Last time I did it I used a 22 way blend. That was in 2022. The first was in 2018. All came in beautifully. I like to make hay on it for the first year (planting year). I would have put down winter rye in the fall with a NT drill, and then came back in the spring with a bushel and a half of oats as a carrier, with all of the other stuff blended right into the oats blend, including very small and heavier seeds, like alflafa, clover, and hairy vetch, etc. I blend them all together with a hammermill (don't use the mill of course)... I call it my "Handy Dandy Seed Tender Blender".
Running the cattle on it after seeding would be just that much more helpful to step the seed down onto the ground better. But get them off when things start growing, to give those tender young sprouts a good chance to get started. And THAT is why I prefer to make hay on it that first seeding year, instead of grazing it.
