    I am looking to buy a good ph tester but I want one that's accurate. I hear a lot of them are junk and unreliable. I would rather not use the chemical test since I want something that’s fast and easy. Anyone have any recommendations on which one to buy?? Thanks

    This sounds lame I know but Home Depot carries a little probe type for about 18-25 bucks, Fennimore or Ferrimore is the brand name. They usually keep them by the seed packs.

    It tests PH and it also tests "fertility" we are pretty sure fertility is just Nitrogen. It is a simple 3"x3" cube 1/2" thick with 2 probes you just stick it into the soil and it has a needle like a speedometer that goes to the level to read PH or fertility.

    We have tested it against a much more sophisticated and expensive tester where you have to make a paste of purified water and soil and put it on a recessed area to read and it comes up in a digital reading. They read the same on every time we compare them. My father in law has the expensive tester we borrow it from time to time when we have serious problems but we carry the Ferrimores for normal day to day stuff.

    I went through a lot of excersizes before I learned what I needed to know about pH meters and pH testing.

    This describes what I found out, how the cheapo pH metes did, how the $100 Hanna Instruments pH meter did, all correlated to soil tests sent in to the NYS Cornell U cooperative exchange.

    I consider this a definitive amatuer study on measuring pH, and how to do it as cheaply as possible but still having reliable results.

    The "in soil" testers are good, but VERY expensive. Bottom line... a good pH meter MUST have a glass electrode. MUST. The accurate "in soil" testers run over 400 bucks.

    I always carry a kitchen soup ladle with me, so I can dig up a nice chunk of dirt and chew on it,
    that way the taste gives me a solid indication as to the condition of the soil.
    Although I have to admit, it is a bit of an acquired taste, and it gets gritty.

    But I tell you what...
    I was seriously considering doing exactly that the other day in front of a savvy
    customer who thought they were so smart asking me all kinds of questions.

    What can I say, wise guys everywhere :p

    Hmmm, interesting, I might consider one of those.

    Google Hanna Instruments. The electordes are replaceable. (They DO have a limited lifespan like a light bulb). The one you posted looks like a non glass electrode type... but there is one that does not have a glass electrode, also by Hanna, but it runs about 400 bucks as in "on soil" tester.
