The edit said rubbish I said bllx.
If you re read the post I pointed out you were totally missing the point in comparing an old rotation to a modern one as they are chalk and cheese.
There is no way you can call any modern cereal competitive in relation to weeds but the old ones are.
Here is a competitive crop of wheat on really poor triple resistant BG land, unsprayed and only 30N. If this was Skyfall or any other modern it would be BG heads only. This is completely unprofitable as a commodity so no use to most farmers today.
You neglected to take in board the fact that an awfull lot of hand labour was done and what would happen to all the extra grass needed to rotate.
Glib sound bites about soil health and sound rotations may sound good but the devil as always is in the detail which you fail to address.
I stand by my post - rotation and diversity
There is nothing new about grassweeds or blackgrass and resistance was created by farmers not nature
