Been growing hydroponically on same plot of cement without soil for sometime now. Zero negative affect on the concrete, plants, or the soil around me.

The term organic being tossed around..
You wouldn't consider a hamburger to be a steak just because they came from a cow.

ya, actually, i got another question,AM,
Drain my nute rez bout every 4 weeks. That gets diluted with 50% well water and fed to my roses and other shit I got going on in the yard.
My waste ro water feeds my swamp cooler. Any more questions?
Do you use soluble nutrients or attempt a microbial nutrient cycling system? There is ongoing research on this. My research on it 15 years back fell flat but I think I know what I did wrong.
Funny you should ask. Tried it with tomatoes once. Here's how it went. Drove to the local dairy farm for some cow shit. Don't speak Spanish so was unable to communicate my wants to the immigrant workers. They pointed me to the house. Approached said house encaged in chainlink with mean dogs. Waited outside for a while. Nobody came out. Went back on a weekend, started at the house. Teenager comes out. I told him I would like some cow shit. He said it would be $20 bucks for the gas. That's a lot for fuel I thought. Followed him out to the huge piles of shit. He fired up a huge front end loader, (there's where the fuel went, lol) scooped up a half scoop of shit and dumped it in the back of my little Toyota Tacoma! Bout brought her to her knees, lol. Anywho, drive it the 10 or so miles home and shovel it out of the pickup next to my shiny new compost bin. Filled up the bin with shit and some perlite and rotated that fucking thing everyday for several weeks. Took its internal temp everyday, added water as needed. A month later I had 25 gallons of "organic" shit which required who knows how much petro to produce. I also bought 40 bags of FFOF for an outdoor crop of weed for the kids. That was delivered to me in bags! Kids killed those plants. Nah, I'm just gonna go with my tub of maxibloom every three years.MG, ever grown in organic soil before? thinking of trying it out?
Well no.. No I wouldn't..man knows ham comes from pig
BUT do ya think them cows were fed organic hay and grain! Lord only knows the antibiotics in there. I laugh at the entire "organic" paradigm!
had to quote myself because of relevanceit blows my mind how many threads in the organic section are quickly side-tracked by hydro growers swooping in to "defend" their methods
Whoa, settle down cowboy, it just ain't for me. I still love all you shit spreaders! Just not my thing. Painting with large brushes it seems to me.so it begs to be asked
what are you doing in a thread in the organic soil section of the forums when all you have is contempt & scorn for organics?
your point is made MG, not sure it was ever on topic or relevant in this thread or even this entire section of the forums
EDIT:
had to quote myself because of relevance
Listening to a podcast I hear some commercial grower bragging his plants were grown "mostly organic". If meat is less than 20% of my diet I am not "mostly vegetarian" I am a meat eater.
Whoa, settle down cowboy, it just ain't for me. I still love all you shit spreaders! Just not my thing. Painting with large brushes it seems to me.

Abstract
There is a concerted understanding of the ability of root exudates to influence the structure of rhizosphere microbial communities. However, our knowledge of the connection between plant development, root exudation and microbiome assemblage is limited. Here, we analyzed the structure of the rhizospheric bacterial community associated with Arabidopsis at four time points corresponding to distinct stages of plant development: seedling, vegetative, bolting and flowering. Overall, there were no significant differences in bacterial community structure, but we observed that the microbial community at the seedling stage was distinct from the other developmental time points. At a closer level, phylum such as Acidobacteria, Actinobacteria, Bacteroidetes, Cyanobacteria and specific genera within those phyla followed distinct patterns associated with plant development and root exudation. These results suggested that the plant can select a subset of microbes at different stages of development, presumably for specific functions. Accordingly, metatranscriptomics analysis of the rhizosphere microbiome revealed that 81 unique transcripts were significantly (P<0.05) expressed at different stages of plant development. For instance, genes involved in streptomycin synthesis were significantly induced at bolting and flowering stages, presumably for disease suppression. We surmise that plants secrete blends of compounds and specific phytochemicals in the root exudates that are differentially produced at distinct stages of development to help orchestrate rhizosphere microbiome assemblage.
