I have a method but i'm not sure if it's a good one.
I mix and the soil with water, and then filter the water. I use the pH meter to find the pH of the filtered water (with soil residue).
I tried measuring the pH of water. Then the pH of filtered water....and found the difference between the two. but the difference is only like 2 pH levels...meaning the pH of the soil is 2?
thanks for your help
