You have a very rich soil. You have huge potassium numbers.

Both samples need gypsum.

You need Mn and Cu.

The green house can use some B.

No nitrogens came through... if you send the lab an email, they may have enough soil left to run your nitrogens.

Thanks Slownickel. I have applied cu zn mn sulfates as well as 3 rounds of gypsum and dicalcium phosphate. The greenhouse plants were later so I nailed the calcium & phos application this time and they blew up during the stretch. I'm ready to send another sample.I'll do some Borax in the greenhouse I think I flushed some Na too.

How things looking? Seeing response?

[slownickel]

What we have seen from several growers so far, from Hawaii, Cali, Oregon and a bunch of unknowns that are running soil samples with the Nickel twist are all seeing the same thing. Over and over.

I know it sounds like a one size fits all. But as our big Caterpillar has shown us is that the big boys know to use gypsum. 80 lbs of gypsum in 3 square yards of a low amendment mix. I bow to such genius. He makes me look like a cub scout. Thanks for the wake up call buddy!

With that said, I can only offer to pay for his soil analysis of his best plant. What say ye all?

[redlaser]

slownickel, did Caterpillar say how the plants responded to that rate of gypsum? I read a fair amount but might have missed it somewhere.

I have some hope that gypsum will be helpful with my excess chloride issue, what are your thoughts on that working? I plan on RO treating the water for future soil and container plants but hope the gypsum will help with flushing or tying up the chloride from a years worth of bad water.

As far as covering a test for a plant, sounds good and would add to your contributions here which are adding up regularly.

[slownickel]

Red,

Gypsum will most definitely help with the chloride. Watch your P and S, they are the competition with Chloride.

And then go look at the photos of Caterpillars place..... LMAO

hey slownickel,

im getting some soil tests done at logan labs, how important is getting the c:N, si, mo, and co tested also? I went ahead and did the aa 8.2 cause of the large amount of carbonate and that raised the price from 25 to 28 per sample..

with the c:N and other traces it came out to like $68 per sample, big difference when testing multiple samples... any feedback?

I have never used Logan. I have heard oodles of complaints only, especially when a couple of folk ran side by side analysis where the same sample was run twice. Historically their numbers seem to be all over the place.

I don't bother with Mo, Si or Co in soil analysis here. I apply Mo and Co as I know there isn't any here in our soils. Many growers I work with get foliar tests for those elements instead of soil tests.

As for Si, we spray Horsetail as a fungicide/Si source regularly.

I would run nitrogens, separating ammonia from nitrate. Logan runs a third type of N, which I don't really understand. Maybe you could ask.

Ideally you would stick some corn in the corner some where and run foliar samples from the corn to compare soil analysis and foliars. If one can't explain the other, might be time to look at a different lab.

At the end of the day, lab costs are meaningless as to the headache and difference it can save you on yields and quality. What is important is the results.

Many growers don't believe in soil analysis and with good reason, the single biggest element in any soil analysis is Calcium. Most labs due to not using the right procedures for their situation will leave you lost, reporting back more Ca than is available to the plant, especially in light of the dynamic and often untested water source.

Congrats on the initiative!

I see Spectrum has the special Kraidy package deal now haha. My soil/water samples are on the way.

Is corn the best crop to plant with cannabis for tissue analysis? I definitely want to try this next year. There are established benchmarks and tissue composition for a crop like corn. Is it the closest in nutrient requirements to cannabis? Does it set fruit at the same time? Does the fact that it's a C4 make a difference?

[slownickel]

Yeah, they wanted to call it that! Too many of you all were sending in samples and they weren't getting posted. It was the easy way for the lab to post them all to my account, but putting a different code on them.

The price is the same as running thing separately.

I like corn because it is easy to read by eye. There are so many photos of corn and it's deficiencies, it would make things easier to read and to have as a foliar reference.

Not sure what else we can plant without begging for insect problems and to follow the same cycle.

What is really neat is that we are seeing unbelievably high levels of boron and the plants seem to love it. No one has an idea of how high we need to take it. This is a boron loving crop for sure.

Glad to hear you are going to run your samples. Ask for the K-2 package. We're getting a great data base!

[Tonygreen]

How much do we stuff in the envelope for the K-2?
