Yea why dont we have nutrient drawdown #s for drug cannabis? Theyre probably out thre for hemp but not very accurate..

Lmao the tan. Is that all clay? Thats a lot of Ca andhigh cec... Probably good for spiking? Havent tried that yet.

Some of those are high ph, why no aa8.2? Couldnt a lot of that ca in thw topsoil exist as co3?

The answer is one of two things:

A) I was not thirsty, or

B) these were trials just to check a couple more top soils. And, I had no intention of running anything but an acid soil. The astute observer might notice both of the ones I plan to run are acidic making an aa8.2 superfluous. It is my opinion that micros are in the top 3 for quality weed. Why would I make them harder to uptake than neccessary?

Everyone is free to believe either of those. I honestly don't give one fuck either way

Hillmizer and i were just wondering about how reported cec could be accurate if its assumed that all the cations present are bound to cec sites... Afaik, the ppms are all the mineral extracted... How do they know whats bound to the exchange site vs free? How could you determine cec backwards from total ions present?

I didn't expect #'s so high from a mix that was sourced on farm aside from the recycled mix and amendments

Base:
Base Soil Mix
2 gallons recycled soil (peat,ewc,perl)
1 gallons peat muck
1 gallon decomposed and ground hardwood (maple,beech,birch)
1 gallon EWC/compost
.5 gallon topsoil
2 gallons perlite

Thinking gypsum and a large amount of irrigation. Still waiting on Irrigation water results.

Would a peat bog in a valley surrounded by pastures collect that much nutrients/salts and store them for over 30 years(last this place was farmed)?

Time to test individual components it would seem.

That bog is likely always collecting minerals and leeching some especially when heavy flooding but bogs are normally packed full of deposits, they just stink to work in / with

A lot of items in your mix could be the culprit, Na & Mg levels are especially concerning to me

Bogs in Mi are like ones in northeast as I understand it, packed full of minerals, like most bogs

So thats your native dirt or the mix you posted? Or are you saying the topsoil contributed all the excess? I would guess the mg and k is from the old soil and ewc/compost. No idea about the salt.

Bcs:
Ca 57.5%
Mg 25.4%
K 7.8%
Na 9.3%

Recycled hardwood, high mg, ca - ewc/compost high in everything adds to it too, peat bog high in most everything in a valley, soil could be high too, old mix as well, pretty much everything in the mix could be causing it / likely is high in minerals...

I was anticipating the mineral content, just not quite this high and with this much mg. It is the Na and Mg that is my main concern also. If I can move those two out of the soil, bring the Ca up and bump the K down slightly I "think" ill be heading in the right direction.

Sample is for the mix. agreed on the Mg and K. My guess is salt buildup in the bog from chem farming from 1935-1988?

Im looking to source as much on the farm as possible, as you can tell. 24 yards of this same mix is planned to be run outdoor this season.

Finally did the correct testing ( shoulda just went spectrum back in September )

What a difference from just the s3 ag test to the k 3 testing ... night and day difference especially on cec and base saturations


OD1 is my outdoor super soil layer , was amended once in November and now trying to "dial" it in more specific for this year

ID1 is 6 year old indoor super soil if been re using over and over and over again.

There are some obvious things that stick or to me such as raising calcium in both , indoor mix seems to have excess sodium and zinc

Can anyone dissect this a bit further as to what's helping or hurting ?

Hooray first time I properly posted an image ( not upside down or thumbnail lol)

The goal obviously to amend within a week or two , cook it . Then re send in, and see what work led to what adjustments.... to develop somewhat of a format for future corrections and teaching

Paint comes installed on most Windows versions.

It will easily crop your info out, or you can select areas to delete or obfuscate.

I lived nearby...lol

Any depth charge in that indoor mix?

Id bring the outdoor soil indoors.

I agree the outdoor is in much better shape to work with , I think for the indoor soil, it's about 3-4 yards , I think I'm just gonna raise the calcium and ph and grow a few vegetable crops out of it and try to drain it if it's contents , then rebuild it for cannabis in future ...

There we go much more clear ... the outdoor soil then will be the one I'm gonna work with

What are you feeding these plants. 27 and 37% Mg, holy shit. I'd just start fresh. CEC of 49 on the one so it'll be a bitch to push cations off
