Yep dd into grazed of cover crop last year . This year the field that is going into soya has been straw raked and left to green up all winter now sprayed off and a false seedbed made at about 1 1/2 - 2 inches max to get another flush of weeds before we drill .
Thinking a JD 750A drill.DD some here, sub-soiled the rest a month before drilling , the packer more or less left a stale seedbed. I think, if anything,the plants that were dd were stronger but our (SimTech) drill is not so good with uneven ground, the plant was less good where we dd , as usual one step forward and two back.
What do you plan to drill them with?
Yes, I have. I’d wager that 75% of the worlds soya crop is dd’ed. Just bear in mind that Soya hates compaction so providing you haven’t got any you can crack on when it warms up a bit. You couldn’t get a better drill for Soya than the 750 because seeding depth is critical, Soya has a fixed length hypocotyl.
