    Does anyone use an electronic Ph tester? I know I could send in samples to Umass and they'd be more comprehensive. But I'm looking for a quick accurate Ph monitor. It'd be nice to have a idea on Ph before appling lime.

    I picked up a cheapy the other day and it doesn't seem to work at all. It reads 8 no matter what it's in. I'm sure it's acidic soil since there's a bit of moss scattered around it. Lots of oak leafs were mulched into the lawn last year along with over fert. I was thinking of hitting it with fast acting lime and then pelletized. Mostlikely OS with fescue an PR.

    I broke 2 of the cheapies last year trying to get it into hard soil. Make sure you use a screwdriver to loosen the ground first. I'm going with a Kelway this year.

    Do not assume moss is a result of acid soil. That is mainly an old wives tale. Same for oak leaves causing acid soil. Perhaps you soil has been overlimed in the past to try to get rid of moss.
    Most moss is a result of shade conditions.

    My cheap pH meters work fairly well.

    Check the pH of beer--should be mildly acid--and the same brand should not vary. The brewry is careful about that. And now that you needed it for calibration--the expense is a business expense--tax deduction.

    Matter of fact, be sure to use your wife in your photographs for your sales flyers. So the cute clothes and hairdo she needs are tax write-offs. Business expense.

    Let us know the acid level of your favorite brand.

    I have a kelway, not that accurate and therefore gets little to no use.

    @OP .... you need to get the soil tested to know how much and what type of lime to apply. Anything less is irresponsible and begging for trouble.

    Riggle, get a calibration standard (buffer solution) if you want to check your meter.

    What is the variance on the Kelway compared to a lab analysis and is that variance pretty standard meaning it's typically a few clicks lower or higher than lab results.

    I have seen as much as 1 pH unit difference.

    I can't test everyone of my customers at a lab. Is there an on-site that you would recommend?
