Hello worm experts! I am working on an experiment using worms for my senior science project. I have heard that worms neutralize the pH of the soil, so I am going to test to see if this is true.
My procedure involves placing worms in 5 different pots containing soil with a pH of 4, 5, 6, 7, and 8. I chose these numbers because they are the typical range for growing plants. Does this sound right to you and are these pH levels safe for worms?
Also, I was wondering how long it will take to see any results. My thought is that since digestion is what neutralizes the soil, I would just have to wait until the worms excrete a bunch. How often do they do that and how long would you expect for it to affect the pH level?
If there is anything else I should do, let me know. Thanks :)
