Biologically Complete +

A biologically complete soil or amendement has a balanced ratio of fungi to bacteria (generally close to 1:1)— and contains all the essential micro-life forms at the appropriate minimum populations, including:

  • Fungal hyphae/spores, beneficial bacteria, protozoa, amoebae, nematodes (bacterial and fungal feeders)

This is the gold standard in soil biology — and GROZOME is proud to meet and exceed it.
