Stump dirt and mushroom compost
dirt to be a miracle
planting aid. But what is it?
The obvious answer is
--- that moist, dark, earthy-smelling organic matter found inside
decaying trees or logs. Different trees create stump dirt of
varying quality; my favorite source by far is our ancient hollow beech
the hillside, while box-elders product lower grade stump dirt.
Maybe hardwood stump dirt is better than softwood?
Naysayers on the internet
report much lower NPK values for mushroom compost, though --- closer to
0.7-0.3-0.3 --- and I suspect our stump dirt is at the lower end of the
fertilizing spectrum. That would explain why the garden beds I
treated with stump dirt last year didn't show much growth --- stump
dirt isn't a replacement for compost. Instead, it makes a great
ready-made potting soil and can also be used like peat moss to fluff up
organic-matter-poor soil. If we ever had enough to apply stump
dirt to our garden in large quantities, I suspect it would act a bit
like biochar, providing spots for
microorganisms to grow unhindered. And stump dirt from
deep-rooted forest trees is probably even higher in micronutrients than the analysis above
