Listening Soil Biome Pt2

Listening to the Soil Microbiome-Part Two.

For comparison 1 week later , August 10, I ran the same experiment on a completely cloudy day, limiting the variable of intermittent sunlight from an only partly cloud day, with slightly greater soil moisture content after a week of intermittent gentle rain..this may mean that I was measuring changes in conductivity in the water on the soil as much moisture and organism/chemistry in the soil - to draw me to this vague conclusion the results were even less clear and random than the previous week. I remembered to do a 'reading' of the surrounding soil outside of the planter boxes for comparison too.

Surrounding Soil- 'Control' Sample.

A 5 minute recording of the surface of the drier rocky soil surrounding the planter box a few feet away from mature fruit tree trunk. A fairly constant steady state but with 4 or 5 different 'pitches' occurring.

Mushroom Compost Planter Bed with thriving herb/weed vegetable foliage and roots.

5 minute recording from the soil surface in the planter box using mushroom compost mix with thriving herb/weed vegetable foliage and roots. Much greater range of notes and faster changes in activity than the surrounding soil (from c2 1to just over c6 a nearly five octave range!)'

Bed B - BIologik VRM Soil Mix

5 minute recording in this bed with specially prepared soil mix and radishes growing. Perhaps even more activity recorded today than in the Mushroom compost mix. (from almost c1 to just over c6 roughly 5 octave range!)'

Worm Farm Soil Mix

Unlike the previous week the recorded surface conductivity changes in the worm farm were not as dynamic-not as rapid changes and mostly between c2 and C5 a 3 octave range.
