Aberdeen MS | U of Mn basically says repeated freeze/thaw will break it up.
That pretty much takes care of the top 2" or so. Anything deeper that will get a single freeze and a single thaw, the process does little as a whole.
I realized the "residue on the ground" factor back in 08. Where I left everything up and tall, I had a mess until the microbial action got into gear. Where I chopped and got it down, was 300% more manageable and pretty much void of residue the next harvest.
I have a less time frame than you do for "prime" temps throughout the year for degradation.
After Jim started his rotational grazing of stalks, he realized the same thing the next year. Hence his "Greywolf Effect". | |
