Well according to this equation
If your runoff pH is lower than your starting pH, us this equation:
Soil pH = Runoff pH - Difference.
For example, say your the starting pH of your solution before it goes in is 6.5 and the pH of your runoff is 7.0. The difference is +0.5, so using the above equation:
Soil pH = 7.0 + 0.5*
Soil pH = 7.5
If your starting pH is 6.5 and your runoff is 6.0, your difference is -0.5 and using the above equation:
Soil pH = 6.0 - 0.5
Soil pH = 5.5
I started with Ph water of 6.6 and my run off was 5.2 for a diff of 1.4 so
5.2(run off) - 1.4 (diff) = Soil pH 3.4 :jaw: sure seems strange to me, But it is just saying I need to start with a higher pH water correct ?
Thinking of maybe water to start at 7.5pH what do you think ?
I made up my 2 pots with exact same measurements and I only tested one so the other is still dry. after bubbling water tonight and until I come home tomorrow, I will check pH of bubbled water, as long as it is a little over 7.0 and test the other pot. will let you know results. I remember Muddy saying I want a run off as close to 6.0 as I can get it.
