Pentetic acid

I also wanted to bring up on the manganese.

When you say we're at four parts per million, on what test? If it's a DTPA test, usually I throw that out.

The DTPA, what we have found is it correlates a lot to soil pH.

It does not correlate to the true manganese level in the soil.

We like the Malik 3 test for manganese.

Okay, yes, I understand.

Your soil test says 1.1 parts per million, but that's a DTPA test.

I don't trust the DTPA test at all on manganese.

I don't think it's a true reading.

I've got tens of thousands of data points to prove that it's not a true reading from what we have found.
