so having finally got a method of measuring ph (the only local shop sells soil ph/moisture meters, which ive read arent great) Ive done some calculations and the outcome is........
bottled water (despite the 7.8ph on the label) is measuring 6.2
The runoff measures 6.5
Soil therefore should equal 6.8 right? Which is actually what the soil ph/moisture meter is reading, so at least that works out, maybe the meter does work after all!
So I think im right in thinking that with the current soil conditions, i need a water reading of 5.9 to give me a runoff of 6.2 giving me a soil ph of 6.5?
I think ive broken something, so simple, cant see the forest for the trees, your breaking up, mayday mayday.
Meh.
