he doesnt say dont use it, just dont expect much in the first year i think. Its a poor video title and worse waste of 50 minutes imo :-) makes me laugh how he talks about adding microbes, like they aint already there :-) What an earth lives on rock dust? I think John has been smoking too much sarsaparilla :-) Where there is iron ore, there is bacillus subtilus, unless you pour salt everywhere of course :-) Its like peas and carrots a famous man once said.Oh God, almost 50 minutes? Can you give a synopsis of why not rock dust? I still have road ass BAD, I can't sit here in one place that long.
Interestingly enough, while I did get in trouble for things as a child, it wasn't for not sitting still. It was for things like refusing to stand or place my right hand over my actual heart for the pledge. I got into SO MUCH trouble for that shit! :p
some people think mountains are actually fossilized giant trees and fauna.I've listened to the first few minutes and it totally makes sense. Where we're going to be living in the high desert the 'soil' is really decomposed granite--sand+rock is what you have. There's probably zero percent organic matter, no clay to speak of until/unless you hit some hardpan down below and so adding rock dust to that mix wouldn't do a thing.
At least it's clearly very high in Ca (as evidenced by the loose, sandy nature) so tightening it up shouldn't be too terribly difficult.
ensuring an active biology and high humic content will restrict the metal uptake, you might however by better off just looking at some ag zeolites to increase CEC if thats the only reason to use, it. Even this would have Al for example, hard to avoid that. Any clay could have a metal. I find media rich in biology has more than enough CEC :-)@Purpletrain You may be 100% right, but I would be more interested in the the rock dust for the CEC qualities of it. Isn't chicken grit just granite? I would be a little worried about the levels of heavy elements that some dusts contain. Some levels may be fine for food, but what about smoke? Apples to cannabis?
over here, Ca levels in the soil are at about 2000ppms plus naturally. I would think adding more would be worthless. Lots of soil I have seen and tested is abundant in Ca, this alone must factor in to its overall importance to wider life. I certainly run at 65% saturation here. I havent pushed up higher, I honestly see less value, what is he leaving out via a reduction? I aint disputing the accolades this number has derived for the grower by the way, just curious :-)Good thread, but take it to the next step. Albrecht, Reams and Tiedjens all came to the same conclusions, (Albrecht after he retired) that Calcium needs to be at 85% of the base saturation. Try it. There is one grower in Cali that does super well at the cup with huge yields and unbelievable quality. He applied 80 lbs of gypsum in 3 cubic meters of a very loose mix, with only a bit of compost. Mainly perlite, etc... That is surely over 90% Ca in the bases!
Yeah thats an awesome story too :-) thanks bro@Ecompost
Big fan of the zeolite.
The Kiowa people have a great story about how Devils tower was created.
"Eight children were there at play, seven sisters and their brother. Suddenly the boy was struck dumb; he trembled and began to run upon his hands and feet. His fingers became claws, and his body was covered with fur. Directly there was a bear where the boy had been. The sisters were terrified.; they ran and the bear after them. They came to the stump of a great tree, and the tree spoke to them. It bade them climb upon it, and as they did so it began to rise into the air. The bear came to kill them, but they were just beyond its reach. It reared against the tree and scored the bark all around with its claws. The seven sisters were borne into the sky, and they became the stars of the Big Dipper."

you should have lots of data online re ag soil tests right? I feel you tho, not many people get soil tested period, let alone share the resultsI have been researching this lately and in particular the sulfer content in gypsum. From my understanding and research, the fear I have with using this much gypsum is having too much sulfer lock out my N.
I was able to achieve 81.5% sat with my mix with only 3 cups of gypsum. I was hoping more people would get their soils tested and post but the thread was kind of a flop in that sense.

@Purpletrain You may be 100% right, but I would be more interested in the the rock dust for the CEC qualities of it. Isn't chicken grit just granite?

When it comes to Science i let the professionals decide.. and that is apply amendments to your soil that is utilized in the short year crops or what everGypsum is rock dust, calcium carbonate is rock dust, rock phosphate is rock dust, the issue is which ones to use. Taking a material like azomite/zeolite (another rock dust) with 12% Al or some other material like it, is suicide. Your yield and quality will never be where you want it. You will always be left thinking why.
Apply good science and good amendments that will give you response is a short term crop. Don't throw the kitchen sink into the mix...
Nothing irks me to the Contrary
people can keep buying there amendments add them blindly and chase there plants all year long mean while others plant and walk away with no need for amendments other then common sense.
30 years ago as a farmer in winter months i worked the rigs from floor hand to derrick hand / Mud man to driller to eventually oil company engineer the Big show with that played with mud from thinning to floculants de foamer . detergents . worked with suspension properties, Fluid loss, filter cake etc
I played in mud from the time i could crawl lol .
Iet alone what i have played with on the farm from Urea to calcium nitrate, to inhibitors
To actual chemicals you could never get . to pesticides or other insecticides Class 1 - 3 that one would need a license to use .
It does not take a rocket scientist to grow a plant or even understand what the plant need
You want to see stupid growth give plants Calcium nitrate and then look the hell out you better have room cause of the explosive growth rates
So where are we @ ??? M guess is 80 percent of the growers if not 90 percent growing weed do not get there soil tested and if they did ???
they would not even know how to read it or where to start
So again you talk like adding gypsum as its the miracle amendment , if you do not know where your levels are @ what good is it blindly adding it you say calcium should be 85 percent ?? when i could say no it should b in the range of 70 - 80 percent an 10 - 20 percent occupying magnesium .
If its to high then there is not enough room left on the CEC to provide MG and potassium
Bottom line unless you have actual soil tests down is stupid to add things blindly
Forgive me my absences, but I try to keep that sort of behavior at a minimum where I see it. That said, if you have knowledge, I can say that I would love to know what you have to share. I am of a like mind but I haven't taken the education, simply read as much as I can in publications like Acres, USA (sorry, not a huge fan of Mother Earth News, too cursory) rather than High Times. I apologize for the poor behavior you've experienced, and if you see me posting something that's wrong, PLEASE CORRECT ME. Seriously. I don't get mad at anyone but myself when there's an issue of information.Uh no i havent met that youtube guy, I have a college education and took hort, and composting classes at the UNIVERSITY OF VERMONT and met like minded folks gaining success all over organic farms in new england, but ill let the cannabis farmers here at thcfarmer who obviously should be teaching courses at universities keep trying to disuade folkswho have PROVEN RESULTS over 20 years of growing. Tis why ignore the shit. I have the truth in my plots! It's not my place to sit in a cannabis forum trying to convince anyone that they are wrong or do things in a wrong manner..................might be a reason why its so dead here at thcfarmer but idk man i made the mistake of giving my opinion and was met with bullshit and sarcasm. that has NO PLACE in the gardening community.
That's a new one for me. I've been poring through the soil surveys, trying to sort out what they really mean, but I am just not well educated/informed enough.you should have lots of data online re ag soil tests right? I feel you tho, not many people get soil tested period, let alone share the results

Thank you for that information, I will be making use of it. :)Love those sayings..... there are a bunch of them floating around. High pH means high calcium. Nope that one doesn't work either.
The balance is what allows biology to proliferate, most definitely. The idea is to help the biology get more air.
Base distributions are about making air space. And I am sorry, but the science has long been proven. Over and over.
You can download a very good book by Dr. Victor Tiedjens, More Food from Soil Science. Even non scientists will get the message. It is free on the Soilandhealth dot org web library. Lots of other great books there too. Soil biology and everything!
It is easy to criticize what one does not understand. If you don't like the concept, maybe ignore this thread, obviously it irks you. No one is trying to irk or sell anything here. I am an agronomist and a farmer..... the real type, tractors and all. https://goo.gl/1U92jS this is an organic farm, we out produce locals by 2 and 3 times who are conventional. Our sizes and quality are both excellent. No weed pics here.
First Haas in La Habra Hts, California, not en PR. :) Estoy buscando para tus limones ahora! (Y, estoy practicando el espanol, no soy capaz de hablando con fluencia.)The first Hass in PR? Really? Haven't been there for years. Used to take the ferry back and from from the DR to PR...
