Soil Test Results (general discussion)

just got my soil test results back. Interesting to me, many soil nutrients are in the "optimum" range. I need to add some nitrogen, but not much.

The only surprise is that I have far too much calcium and magnesium (both). Previous tests I had done by the lab at Cornell, but this year from U of Delaware and the readout is different. It shows both calcium and magnesium off their scale.

Not really sure what that means...I'll research, but would like to hear any thoughts about it from y'all.

Does it give you a Ph figure? Is that in range? Generally Ph is too acid, that is why lime needs to be added occasionally. But too much calcium would mean you are the other direction, which doesn't usually happen. You haven't added lime real recently have you?

Ph is 6.1, yes, considered inside the optimal range for most veggies.

Our soil here is limestone based, so no, I don't add lime. I thought adding lime would increase Mg and/or Ca...no?

Yes, and the added calcium, a base, is what adjusts the Ph to get rid of the acidity.

I am getting out of my "smart range", so I don't know how they figure the calcium at being high.

I know if you add crushed limestone to correct an out of balance Ph, it takes several years for that limestone to break down and do its jobs. So on soil tests they usually ask when it was limed last. Knowing that if it was limed recently then it all would not be broken down and that would skew the test results.

But if they were saying the calcium is high, but Ph Ok, then wonder if they are talking about a different form of calcium?

Think that is a question for your local ag expert or Extension person.

Good luck, Gene
