|What is an effective method of testing ph in established beds? The cost of soil sample tests in Ga. is prohibitive when you're talking about 35 raised beds. What with the makeup of the beds coming from different sources, having different kinds of manure, etc., does anyone have a good answer?|
I was informed at a particular Master Gardener session that the "store-bought" contraptions were totally unreliable. I have reason to suspect ph where such a drastic difference exists in side by side beds rife with nutrients.
A reliable contraption would truly be welcomed on my mountain.
I'm just askin'. Bubber at Chinquapin.

|The store bought contraptions aren't totally accurate, however, most are pretty close if used correctly (such as making sure to clean probe after each use). The testing kits with the tablets you add to water (bottled) would probably be more accurate, but each kit usually only does 10 ph so you would either have to google soil test kits and find one that does more or buy multiple ones. |
Does your local agricultural extension office not offer FREE ph testing? The one here does, but if a more indepth soil test is needed then it will cost a little for each test, but not much.
Most of these kits come with the test for N-P-K also so if the ph is fine then you could test and see if one of these other areas is too high or low.
