Elemental sulfur (dust) can help acidify soil if you have the microbes but the S will bind with your Mg and Calcium, if your saturation of ca is below 65 or so you will leach out calcium with S before any Mg, this is not the problem for you.

I would agree though as I have dumped 50 kg on roughly and 30 x 30 area to see if I could get the pH down for a chance to grow acid loving crops, problem was it didn't move the pH in two years aside from a couple 0.1 up, whereas where I did gypsum, potassium sulfate and rock phosphate (calphos and Spanish river carbonatite) the pH dropped a couple .01. I tried mixing in a few bales of sphagnum peat moss to bump up some organic matter at the same time (organic matter is 5 in my clay soil). Even with a cec of 14, calcium at 75% and Mg at 20% the pH didn't go down. Either I didn't get the sulfur where it needed to be for the microbes to turn it into sulfuric acid (this is my guess as I just top dressed when I should have tilled it in 6 inches) or there is another trick to it.

The only reason sulfur can lower pH is the bacteria than can process it turn it into sulfuric acid, it can take 3 months (in every aspect of ideal) to a year to see some change so it can also be easy to over do it and go too far, I would suggest working it in 6-8 inches if you are going with sulfur but do not apply more than once a year. If you're noticing your Ca saturation drop take into account your sulfate in gypsum if you plant to apply that, although calcitic lime is a great one to add when sulfur isn't needed.

My biggest concern is can we get o2 in that soil or not. If we can't minerals don't mean shit

I love me magic 8 ball. It got me through more than one t/f test
If you want to aerate a soil, run a subsoiler in 36 inches or so and with a real soil analysis treat the soil for 36 inches of depth discing in gypsum finishing up with raised beds to maximize air space.

Get enough gypsum on there and forget about pH.

Or forget all of that and do what all the Colorado alfalfa guys do and drown the place in sulfuric acid.

Let me understand this. Someone posts their lousy analysis in this thread, I make comments and you are picking the options? LMAO.

And then if they screw up, you will be there to help? Maybe if you guys all got together, you could run those K meters in series and get a super K meter...

I know this is off topic, sorry.

Anybody know a concentrate artist that is good, and doesn't already have a legal business? Please let me know in PM's. SlowN?

Carry on please.

This is why it is so critical to have a real set of numbers, make a real plan, work the plan and then check your analysis from time to time to see if you are getting where you want to go.
In regards to light weight mixes...I've been submitting my soil samples without any aeration added. The results show cec values in the mid 30's. If I add aeration components after testing what effects does that have to cec,overall nutrient availability,ph etc.? Currently am using perlite only at 33%.

Am I correct in not testing an inert component (perlite)in the initial mix?

Jack- I sift my samples and weigh them as is for ammendments

So yes I am a big boy and even when people tell me exactly how to do it, i find a simpler way. Sometimes I have to learn the hard way as I am this morning after trying to drink with my mom last night. Seen alot of people fail and I've kept up many times...there are no winners.

I'm gonna add alot of amendments, till deep as I can and we will see the results. I'm pretty sure I will be just fine and some people will learn something. I will for sure I just hope it's not a hard lesson, i hate those ones. Either way I'm not gonna let the door hit me on my way out. This CO gig is coming to an end. Im gonna get what i can while the getting is good.

Edit The best part is my employee is headed to work with the excavation crew. I'll be left with my wife, buddy's wife and father in law to clear the trees on the hemp plot. My father in law is older then the land were clearing, he's getting dimetia and I may have to put him down lmao

Had a request on how I calculate base saturations using the M3 and AA@8.2 (which was discussed before, but what the heck).

It is real simple.

I only utilize the Ca number from the AA@8.2 which is the only element which will set up for the most part in carbonate form. K, Mg and Na from M3 are utilized along with the Ca from AA@8.2

I don't use H estimates, instead I lime to fix the pH if necessary and aim at 80 to 87% Ca depending on whether the soil is sandy or heavy....
