With the release of the John Kempf episode, I wanted to start a discussion on gas exchange found in different forms of mulch.
These two studies provide an excellently detailed overview.
Is anyone else focusing on gas exchange in their mulch? Any noticeable differences as you switch between different mulches?
Do some of the trade-offs, such as with cardboard, still feel worth it (high protein material for worms but lower gas exchange, perhaps unless more holes are poked through)?
Any thoughts on using different mulches during different stages of farm and/or crop development (e.g. one that you would use, knowing gas exchange considerations, to break in the soil but not to mulch a crop)?
