12.5cm or 15cm Drill Spacing
- Thread starter Fragonard

I'd go 6"
We have a Moore direct drill with a tine bar in front and a Pottinger combi on 6"
The combi replaced a farm force drill on Krm discs, and the soil and trashflow is far superior on the Pottinger, especially with the press wheels removed, it's almost unstoppable.
Interesting conversation with a contractor today, they have a 4m combi at 15 and a 3 m on 12.5...he remarked that last year they struggled with soil flow in the wet conditions in the wide spaced as it lacks length between the coulters...but also the narrow drilled barley was standing , the plants propping each other up rather than necking into each other on the wide spaced and the heads dropping low in short corn....interesting i thought
We've tried 2 demos of 15cm spacing both were half fields so no different treatment other than the drill.
The first in winter barley which was perfect no noticable difference at all .
The other was spring barley which put is right off there was a big drop in yield and straw on that half it looked grand but didn't harvest well it wasn't any weedier than behind our own so no reasonable explanation but we stuck with 12.5cm

Do you mean, they struggled with narrow spaced?

Does anyone drop to 10cm then? I have an old nordsten drill on 12.5cm with unused outlets and a spare drill breaking so I could add some coulter's. Only used for about 25 acres of wholecrop and some roots and sometimes grass. The book has settings for 10cm

No particular negative But drill will work better in wet with wider spacing but I don’t reckon that’s much of an issue for you so no real adv@ntage either

For my farting bit of drilling I can wait until it's dry usually. Is there any difference in yield between the different spacing?

I have 6” spacing for barley and customers like it but for grass I have 4” and works well
Do you have blackgrass?

Went from 15cm Horsch to 12.5cm vaderstad,12.5cm always looks thicker but don't think end result is any different,always thought there was a bit more weed pressure with the wider rows though.

we have 3 meter with 32 rows & it has helped keep weeds down & yields are up with it , but needs a nice clean seed bed to work right in

How many rows of coulters? Sub 10cm spacing is close
