Harry's farm a few months ago had done some soil sampling and briefly pointed out his worst land was the stuff often baled by a neighbour . I don't know if he ever covered it in a follow up video as sounded interesting.To some, it may seem strange that @Clive would want to remove and sell straw, rather than use it to help build up SOM.
I happen to see his point in doing so. In the early years of converting to DD, Chopped straw can be a hindrance in crop establishment. The loss of this potential SOM benefit can potentially be got round far more beneficially by using Cover crops.
On top of which, by the time you have been DD farming as long as @Clive has, SOM levels may have increased to such a level, that removing straw isn’t going to have much, if any detrimental effect.
I’ll bet that if and where @Clive believes that straw is better chopped, he will do so.
