Now's the time. As we terminate secondaries we have the fresh young leaves needed to do specialized tissue analysis.

My lab needs:

10-15 FRESH young leaves. Packed loose in crumpled paper. Shipped UPS or USPS Next Day Air ONLY on Monday, Tuesday, or Wednesday.

Private emails since CLC doesn't do new retail/consumer accounts anymore.

This is the only good chance all year (without screwing up the plan) & just in time for fruit-set.

I intend to charge only the $65.00 we charge all large commercial interests. I make nothing on the deal at all. This is a good faith gesture only & is limitted onlky to those submissions I can handle.

Since I live in Europe I´m out of the game, but I would be interested what a specialized tissue analysis is good for and how you can improve your season if you have results.

I compare the tissues nutrient analysis with that of the soil. The lab has nutrient "standards" I had them modify for the rediculous yields we anticipate. Basically a modification of a commercial cucurbit program with a "twist".

What would your test tell us that the $14-$20 tissue test from the U Mass Soils Lab not tell us?

Thanks for the info.

JimR, Umass charges $14-20 for SOIL tests depending on what you request. I've never had a TISSUE test done, but I'm guessing it's pretty expensive. Just want to be sure here that we're comparing apples to apples !

Soil test from U Mass are $9-13. Tissue tests are $14-20. Read the list of services from my link. I have used their lab for quite some time. Here is the info right off their site.


Plant Tissue Test (without Nitrogen) .................................……................$ 14.00

A determination of the Total Tissue P, K, Ca, Mg, S, Fe, Mn, Zn, Cu, B, Mo, Pb, Cd, Ni, and Cr. Analysis by ICP Spectrometry of dry-ashed sample in 10% HCl .

Plant Tissue Test (with Nitrogen) ............................................……..........$ 20.00

A determination of the Total Tissue P, K, Ca, Mg, S, Fe, Mn, Zn, Cu, B, Mo, Pb, Cd, Ni, and Cr. Analysis by ICP Spectrometry of dry-ashed sample in 10% HCl . Also included Total Nitrogen by catalytic combustion.

Tremor's offer is more interesting to me than a regular tissue test since our yield expectations are profoundly rediculous.

Does UMass utilize a "modified" standards comparison like Tremor described?

UMass uses the simplest single extraction methods available. Ironically, the multi-agent extraction methods that CLC & Harris Lab's use were originally established by Penn State. And even Penn State no longer uses these advanced extraction methods. As a quasi-public agency they can't afford to.

Harris & CLC Labs are the only 2 labs in the country using these methods.

Good results can be obtained using the single extract methods (soils) if no unusual complications arise. I especially trust when an "tenured extension agent" uses these tests in his own county such as the case with George Hamilton in Hillsborough County, New Hampshire. He knows the growers, the soils & the test procedures in his area like the back of his hand.

But if I sent him my soil, he'd be out of his element. And the archaich test procedures might not give hinm all the data he would want to have.

CLC & Harris charge enough money to cover all expenses plus make a profit just like any business.

I stand corrected and appreciate the info, thanks JimR :)Duff

FYI - from Henry's:

"keep in mind regarding tissue analysis is that if you have done any foliar feeding prior to tissue analysis you will have skewed the test results due to foliar fert. residue in the tissue"

I always have liked the information Henry provides. This is whay I prefer to test only tips.

Kenyon, Mn.

Tremor, the Multi-agent procedure you speak of would that be Kjeldahl digestion for Total Nitrogen and a Nitric acid/Hydrogen Peroxide Digestion for all of the other nutrients including Total Phosphorus?
