Everything on this planet was sterile once upon a time

“Everything on this planet was sterile once upon a time. Mother Nature has built it through a successional system.” 

In very brief term, our planet has gone through the changes in fungal to bacterial ratios in the once sterile sand, silt and clay through succession — from bare soil, to weeds, to brassicas and early successional, not-very-productive grasses, mid-succession grasses and vegies, to late successional meadows and pastures, crop crops, to vines and shrubs, to deciduous trees, to old growth evergreen and conifer systems.

The landmarks are: (“F:B” = fungal to bacterial ratio in soil)

  • Sterile bare planet to 100% bacterial to
  • F:B=0.01 for cyanobacteria, true bacteria, protozoa, fungi, nematodes, microarths to
  • F:B=0.1 for “weeds”, high NO3, lack of oxygen to
  • F:B=0.3 for Early Grasses, Bromus, Bermuda (e.g. spinach,) to
  • F:B=0.75 for Mid-grasses, vegetables (e.g. broccoli, carrot) to
    F:B=1:1 for Late successional grasses, row crops (e.g. tomato, corn, wheat) to
  • F:B=2.1:5.1 for shrubs, vines, bushes (e.g. strawberries, timothy grass) to
  • F:B=5:1 to 100:1 for Deciduous trees (e.g. apple, berries, nuts) to
  • F:B=100:1 to 1000:1 for Conifer, old-growth forests, (e.g. red wood, pecan, chestnuts) etc.

So, if we know where the plant we want to grow exists on this successional system, we can put the right biology (in terms of F:B ratio) back into the soil through “compost” and “compost tea” (which contains the necessary biomass of fungus and bacteria) and we will create the best condition for the plant as this is how Nature works.
