soil is more brown than mine is. I dug a lot of this out in the winter so I could get a shovel in it. It comes out
in solid blocks like hoop cheese. After I packed the holes with wood and leaves and anything I could find I
a few days would pass and the blocks could be broken up some and put together with compost, manure and
so forth. I have seen giant pine trees grow out of this stuff or else I would have never put it back in the beds.
As I said earlier the clay eats the amendments rubs it's belly and burps.
Alex, you should think about putting away the shovel and investing in a digging fork. Before you go about your preferred mulching method go through the area and loosen it well with the digging fork. In my experience gardening in the grey, silty clay of coastal, CA a lot of the nutrient loss you are describing comes from runoff because the good stuff can't penetrate the compacted clay. Once clay does get a hold of nutrients and amendments it won't let go, which is a good thing, and as long as you give the good stuff a pathway into the soil you can make that happen.
In smaller, more intensive plots I (when the soil is dry) have had success doing a one time tilling in of some texture improving amendment like finely chopped straw, lava rock, really really coarse sand, cotton seed/rice hulls, etc. and then going ahead with the sheet mulch. I usually do this in the fall and let it rest for the winter so its ready to plant in spring. Good luck with your clay adventures y'all, definitely a challenge
