Thank you .. Every Day's A School Day here
being an Urban person, I am clearly completely ignorant of such matter, although I did note
If a soil has poor drainage, it may need drainage tiles or other devices in order to help with the removal of excess water under no-till. Farmers should remember that water infiltration will improve after several years of a field being in no-till, so they may want to wait until 5–8 years have passed to see if the problems persists before deciding to invest in such an expensive system.
Perhaps this is part of that transitional period?
Anyway, thanks again, and I will re-transmit those links back to Yorkshire!
