Funny you say this, there is a thread running on a drilling Facebook group of someone who has sold his 3 year old Mzuri, straw rake and special ld subsoilet and going back to top down and vaderstadt. Saying the land is now compacted and subsoiling doesn’t work, wet areas appearing.
Obviously loads of comments ‘direct drilling doesn’t work’.
I’m currently looking to get a LD subsoiler but things like this worry me…they have to lift the whole profile. We were (literally) crawling along with a challenger and 5 legs this year but were lifting the whole profile visually 12” deep. When I look at these LD things I do wonder how much they will achieve in comparison. We had destroyed the field in question with beet lifting the year before (don’t ask) so I’m just hoping they were extreme conditions and an LD would be sufficient in a normal year
I did some this year on some headlands and I don’t think it achieves a lot for us. I think where we do have issue on some fields the damage is fairly near the surface, I am thinking about a second hand Claydon to use on targeted fields with issues and to drill beans/give us a wetter weather drill. I don’t think low disturbance subsoiling is the answer to any shallow compaction issues we see sometimes.
If you are going to subsoil, then subsoil and move the soil to alleviate the problem, but the subsoil must be dry otherwise you are achieving nothing other than making the situation worse.Do you need to use an LD subsoiler?
The past 2 seasons have been very wet Autumns and Winters, followed by very dry Springs and (early) Summers. Which have created massive cracks in the soil which probably have done far more good than any Subsoiler.
EXCEPT when you have damage caused by harvesting Beet in those wet Autumns, which is inevitable.
The trouble being that if you grow Beet and this happens, trying to go DD and Regenerative, it is going to be a real struggle, if not impossible, until unfortunately, you stop growing such crops as Beet!
Is a Mzuri a Direct drill?
Yes insofar that it is a one pass drill without the need for prior cultivation.
No insofar that it doesn’t need prior cultivation, but moves and stirs up far too much soil, causing OM damage and loss of Carbon.
Perhaps therein lays the problem and why it doesn’t work causing wet areas to appear?
LD subsoilers are an oxymoron, pointless. The other fallacy is because they are low draft you can use them in wet soil. NO. NO. NO. They are compacters in wet soil, not subsoilers.
I passed someone out with their Sward Lifter in Bledington last week. So I stopped to have a look. It had very neatly compacted the soil above and below the point and created nice mole drains. Not so much lifted as compacted. And I believe this is what people are doing with the strip till drills, drilling later, because of a mistaken belief it will help control blackgrass, into wetter soil and actually creating compaction with the leading leg. No matter what design it is, the leg if run too deep in wet soil, will not lift but compact.
