That's the reason that they are around. They have a purpose in nature....To be honest I went into DD thinking it would help BG. And initially it did, but crops looked hungry on the back of no mineralisation.....so I added fertility in the form of manures and starter ferts, and the BG came back!
Now I DD cos I genuinely find it easier asto what I should or shouldn't be doing.
I'm sure all these stacked residuals are knackering soil life in the top inch.
Spring oats / barley can cope with 10x the blackgrass wheat can
Blackgrass doesn't really compete with beans or decent OSR
Winter cereals don't suit no till on well bodied soils unless you have big summer covers or Knee high OSR vols to get the water out.
Photo below shows (dead) thistles doing their part of structuring and wicking water out....not all weeds are enemies.....
they are only enemies for your pocket unless you can sell them for a profit. Maybe a new enterprise to seel the thistles as flowers in shops?
