How about a gypsum slurry fertigation with solution grade?

Mike does not like juice....

A slurry of a fine gypsum would work. I think applying it to the top of the soil as a dry would be easier. Keeping gypsum in suspension is not easy most folks have special equipment for that.

It is very real and highly probable that when one really dials it in precisely, that we can go where few have gone before.

All these guys in Ca, Maui etc... with 80% Ca soils are not magicians. They can be nearly the worst grower in the world and they will still come up ahead, why?

A Ca rich soil is rich in microbiology, air space and allows air to get down deep into the soil. A big part of the reaction to Ca is that Mg and Na get pushed out. Sort of like musical chairs, someone has no where to sit and gets pushed out. Those wonder yields and quality come from a good soil. And of course there are guys that can push it as a result, no doubt. But put that grower in a 50% Ca soil and watch what happens. Suicide.

1 Meq will push out 1 Meq, so 1 Meq of Ca, will push out 1 meq of the weakest bonded, most like Na and then K. Mg is the bitch that won't leave and in many cases is the biggest job we have. She is a fat slut that can't get through the door. It takes a lot of flocculation of soil/medium to get her out. If you need Mg really, use sulpomag (0-0-22-18 Mg). It is a mineral and won't react like mag sulfate or mag nitrate. Keep her tied up in that mineral form.

Watch that video in the beginning of this thread again. Listen to the message over and over. Mg is your enemy, not your friend. She is pretty and talks a nice story, but at the end of the day, she stabs you in the back.

If you see a Mg problem, 99% of the time it is because K and Na are high or you don't have enough P. How do you figure that one out without an analysis? You can't. Much less dial it in.

Applying foliar Mg sulfate or nitrate works fantastic and you will often see a clear response. Mg is very mobile in the plant, so if you really need it, the leaves will send it down to the roots. DO NOT APPLY Mg to the soil. Took me more than 20 years to figure that out. Carey Reams and Doc Tiedjens all explain this is their books. Unfortunately when I was young and stupid, I dismissed Reams immediately. Tiedjens I didn't find til several years ago.

Tiedjens was applying dosages of calcium like Cateripillar (1 lb/cubic foot of gypsum, plus bone meal, etc.). Tiedens applied upto 40 tons/acre of lime. I shudder at that idea knowing what the pH would go to. That is why you will keep hearing me repeating gypsum, gypsum, gypsum. You need to get numbers and then do trials. 1/2 dosis, single dosis, 1.5 dosis and double dosis. You choose what you like. That is your game plan.

Try it, you'll like it. Mikey liked it....

Pure poetry!

I'm glad I stumbled in here. I've come to the realization I've been doing shit ass backwards when it comes to my soil. I've had my nose jammed in genetics papers and books for so long my skill as a grower stopped developing awhile ago... I'm surprised I get 1-2 a light tbh. Winging it too long... Lots of work to catch up.

Appreciate everything greatly slow.

Looking back through my albums has been a shock. The things you have been pointing out to me have been right in front of my clueless ass the whole time.

Onward and upward. I've got some work to do.

Tony,

Congratulations, you are on your way. You now have more tools in your toolbox to figure things out. Many folks resist and don't want to learn, closed up in their own little world.

Sometimes one needs a small disaster to wake them up. Unfortunately, many still don't get it.

Keep going!

So. All of us canna farmers don't have reliable access to tissue analysis. What does Slownickel and everyone else think about horiba (or other) ion field meters.

I've got the soil analysis, but now I've got heaps of excesses. Can I be using these meters to dial it. I have heaps of sulphur and K and Na. Can I still be applying K foliarly during this bloom using meters for guidance?
There's not a phosphorus meter that I'm aware of, so go for broke to get over the sulfur excesses?
I've got my sight set on a K meter and a Ca meter but I don't want to waste money.

Sulfur excesses? We looking at the same analysis?

We're not. My spectrum analysis says 500ppm sulfur.

Your P exceeds your S. Your S is ok at 500ppm. The green house needs P. Your energy is low there in the greenhouse.

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.
