Science experiment coming up - need your input...

16 years ago

Need your input in regards to tools to measure the acidity levels in the soil.

My daughter has to do a science project and has decided to take soil samples from our property, some from the woodlands, some from the meadow, others from the gardens, etc.

I can't seem to find some cheap lithmus paper (I think this is the stuff that measures acidity), but have stumbled upon a local garden center which sells these probes which measure the PH in the soil. Below is a link to it.

Anyone ever use these things? Your thoughts?

Here is a link that might be useful: PH soil tester
