Reamend Old Soil?

That's part of the Mehlich 3 test. The base saturation ratio is just a calculation of what could possibly be tied up and I would be fucking tickled to death if you knew how to calculate that shit. You are missing a solubility test like a saturated paste test, which proves to me that you really don't know that much about soil testing. When you start talking solubility tests, then you can approach me. I think that a Mehlich 3 test is tits on a boar, completely useless w/o a solubility test. I've had plenty of Mehlich 3/Saturated paste tests to know that it gets expensive quick and it's usually $100 for both at Logan Labs or Spectrum Analytic. Until you can post some pics of soil tests, maybe you should just stop this. You don't know SHIT about soil testing. Please, post some pics! You are speaking on a subject that you have zero experience.

I find that CEC really isn't important in potting soil, it's more for farmers with fields. I usually have between 40-60% organic matter in my potting soil, what difference does it make if it's 28% or 60%? The base saturation is just Ca, Mg, K, and Na.

Copy and paste:
Base Cation Saturation Ratio
(1945) suggested that the base saturation of the cation exchange complex should be in specific amounts of 65% Ca2+, 10% Mg2+, 5% K+, and 20% a combination of H+, Na+ and NH4+.

How is your base saturation test going to tell me that my manganese is being locked out? The ONLY information that I find important on a test is what is being locked out. I'm going to stop spoon feeding you this before I convince you of buying this test. Shit, I hope that they don't sell it in Canada! I hope that you go your entire life w/o using this test!

Yes, perhaps I am a fool. But this fool would rather send soil samples to an accredited licensed test laboratory than from some LLC listed on Amazon. You feel differently, and I can live with that. Thanks for your input.

The difference here is that I HAVE used the other testing services and I am sharing my personal preference on testing. I think that only a solubility test is important, fuck that Mehlich 3 test straight to fucking hell!!!

Where's the other nutrient amounts? How much N is in it for one thing? Or am I missing something?

From what I’ve gathered online, they don’t test Nitrogen levels, since the results will vary and it wont be accurate.
Was planning on throwing some alfalfa or neam meal to cover the nitrogen aspect.
Not sure why they only listed Calcium and Mag for micros, it said it would include all of them, but I’m not too worried about the others.

Strange. I've never heard that, but I've also never tested my soil.

Yeah, don't quote me on that lol.
Just after comparing a few soil test companies, I came across a few threads that mentioned they didn't test it because it would not be accurate.

I'll quote you on it, because it's true. lol

Most basic soil tests don't include nitrogen because it's a bit more involved. And paying for a more expensive test that includes it will only let you know the available nitrogen which is of little use to even conventional farmers. The method soil labs use to analyse potential nitrogen is called "Solvita Soil Labile Amino Nitrogen" test, or SLAN. It's a whole other test, so you can usually buy it alone or in addition to a standard test. Here in Canada the cheapest SLAN test I know of is $25 a sample.

I've never worried much about nitrogen though. I'm not sure where my N comes from, but I never seem to have a shortage.
