Question on Iron & Zinc
My recent soil test shows Fe 1ppm and Zn 0.7ppm. These seem a little low. The Ph was 7.4. Overall a good test, but questioned these elements.

Did you get the test done at Logan Labs? If so, post the full results.
If not, get a test done at Logan Labs and post the full results.

Re: Question on Iron & Zinc
Yeah, that doesn't sound like a Logan test--it sounds like they were trying to test free iron, which I'm surprised would be as high as 1 PPM at a pH of 7.4...

Re: Question on Iron & Zinc
This is exactly why we can't provide interpretations for labs other than Logan Labs. Most people think "a soil test is a soil test", but different testing suites use different tests and result ranges, and we can't (as volunteers) know all the hundreds of labs and their optimal ranges. One lab uses tests that tend to range between 1 and 15 for Iron, and another uses a test that tends to range between 75 and 250. We just can't do them all...
