What is the most reliable and affordable soil ph test kit that you don’t have to mail in a soil sample?
U can a aoil tester thats like a ph pen but it has a different prob on it
The probe you use for water can be used for other matrices.
Worked in labs for 15+ years. The probe that did soil pH or equilibrium pH on foods was the same probe that tested water.
Just google EPA or FDA methods for pH testing - all just say pH probe.
This is my experience only.
I personally have a Hanna ph soil tester that cost like $150-$180 can’t remember honestly its been a hot minute. If you don’t want to go that route ypu can look up how to do a slurry test to reliably get ph and ppm reading
Same as @Caligurl. I’ll often run a slurry on a bag of amended medium just to see the numbers before I drop a seed or transplant
