Mafic means: of or pertaining to rocks rich in iron, magnesium or other dark minerals. Ultra being Highly.
SOO Ultramafic soil.. soil highly rich with rocks containing iron, magnesium etc... As opposed to soil containing sedimentary rock (sandstone, limestone etc)..
Basically means a very gravelly soil but one which is pretty unaffected by the gravel since it is very dense and insoluable. The important thing here is that it is loose and drains FAST because of the high gravel content.
I would imagine the Sphag would be fine as long as it is not over compressed.
