A disk is good to get the lumps broken up. But 6 times across & you make a pavement out of the ground....
What all 10-acre folks want to do is plow on Monday, disk on Wednesday, & plant on Friday.
Doesn't work well that way.
Plow in fall, let the frost mellow the soil, disk once, maybe 2x in spring, harrow if you need more leveling, and you have a wonderful seedbed.
At least let the ground get rained on a few times if you plow in spring. And don't plow in spring if the ground is too wet - makes bricks, and you won't get those lumps worked down.
If you have to plow, disk, plant all in the same week:
Plow it.
Disk or harrow it when the lumps are dry on the surface, bust still wet inside. The would be within 24 hours or so. Timing is _critical_ on getting those lumps broken up nicely. Dry outside, moist inside, & a disk will do a lot for you.
Wait a day or 2, then work it again. Would be perfect if you could get a light rain on it before working again.
If you need to disk it more than 2x, you will have issues. (And, I've had issues, happens some years!)
After plowing, there shouldn't be much for grass patches.....
Many times a worn out or too light disk is used, it doesn't cut well enough.
In real farming, disks have pretty much been parked in the grove. Field culivators do a better job of soil prep. They lift the lumps & stuff to the surface, leaving a nice seedbed of fine soil a couple inches down, where the seed will be. Also the lifting action helps airate the soil, while a disk packs it down.
Plowing a second time is a drastic action, it doesn't work well in sod, and again you will have fresh lumpy soil to work up all over again..... Yea I've been there too.
Random thoughts as the learning process continues.
