Hello - I have a small garden in UK with heavy red clay that had been compacted by machinery before I moved in (what a nightmare).
I'd like to dig a composting pit perhaps 3 feet deep to fill with vegetation. I won't want to access this later - the idea is just to slowly work my way around the garden making these pits to get some much needed life in the soil.
I am stuck on the science bit. Should I get fungal life going first with underground hugelkultur type composting (tree branches/composted bark)? And would fungal growth happen down at the bottom of a cold clay pit?
I thought of putting the branches/woody stuff on the bottom half of the pit and then filling the rest with used organic straw/manure. However, would the heat from the decomposing straw/manure kill off the fungal growth developing (hopefully) on the woody stuff underneath?
I thought that once my pit gets activated and sinking into the ground, I'd top it up with kitchen waste type composting.
It seems that composting wood to get fugal growth is very different to traditional type composting of kitchen waste. In the woods with the deep spongy leafmould ground, there doesn't seem to be any worms amongst the years of falling leaves. However, when I've composted my kitchen waste there are worms and obvious insect life aplenty.
I'd really appreciate your opinions!
