You know what our body uses as a natural battery sort of thing? Salts! You know what is loaded with salts/electrolytes? Gatoraid! The conclusion is clear

Barley seedlings, traditionally not grown in hydroponic systems, exhibited a 50% increase in growth over 15 days when their roots were stimulated electrically using eSoil.

I didn’t know barley is such a masochist plant. I wonder if it’s just barley being weird, or if other plants also like being (lightly) electrocuted.

This is really only a useful technology for hydroponics, which is really only a useful technology in places that are short on arible land, but the realities of globalization means good luck beating the costs of importing from places that have more arible land than you.

Still neat, I would have liked to have seen an explanation for the change

  Hydroponic is way more efficient than growing in dirt. You can stack it as high as you want and grow way more per acre. On top of that you have the reduced amount of fertilizer and the increase in growth rate.
  
  There is a reason why the best weed is grown via hydroponics.

    It depends on what you mean by efficient. Cost efficiency wise, normal land farming beats out hydroponics by a mile. And really, cost efficiency is virtually the only thing that matters when it comes to farming on a massive scale.

    Only if you want to use incredible amounts of electricity and occupy a lot of building space. Ignoring those things it may be more efficient but not when you look at the whole picture.

    Efficiency doesn’t matter when we have huge amounts of low-cost arible soil. We don’t need to make the most of every square meter when it’s cheaper and easier to just put seeds in soil. This is the problem.
    
    Hydroponics are cool technology that is in every way “better” but useless.

    The best weed is grown in no-till soil, hence why living soil weed sells for more money.

    Hydroponics, when combined with indoor, vertical farming, is the reason that the Netherlands are one of Europe largest exporters of food. Even though they’re one of the countries with the least amount of farmland.

  Also quite useful for places short on water, or daylight, or clement weather, or low-value ecosystems, or where transportation is unfeasible due to accessibility, environmental conditions, market access.
  
  Also quite good to alleviate food deserts, securing strategic supply chains, and supporting urbanisation for greenification, food supply, lowering transport and food security (with growing food also having positive mental and psychosocial effects).

    You’re always gonna have problems lifting a body in one piece. Apparently the best thing to do is cut up a corpse into six pieces and pile it all together. And when you got your six pieces, you gotta get rid of them, because it’s no good leaving it in the deep freeze for your mum to discover, now is it? Then I hear the best thing to do is feed them to pigs. You got to starve the pigs for a few days, then the sight of a chopped-up body will look like curry to a pisshead. You gotta shave the heads of your victims, and pull the teeth out for the sake of the piggies’ digestion. You could do this afterwards, of course, but you don’t want to go sievin’ through pig shit, now do you? They will go through bone like butter. You need at least sixteen pigs to finish the job in one sitting, so be wary of any man who keeps a pig farm. They will go through a body that weighs 200 pounds in about eight minutes. That means that a single pig can consume two pounds of uncooked flesh every minute. Hence the expression, “as greedy as a pig”.

Years ago I was following “alternative science” channels (for fun) and one of their ideas was to put metal rods in a field and apply current to increase plant growth. Their other ideas were intelligent plasma generating free electricity and using water as fuel so I dismissed the “electric soil” idea another idiotic experiment although the least crazy one. Could the be on to something after all? Not with the intelligent plasma of course, just the electricity and plants.

  The browns gas thing (usually “using water as fuel” by splitting it… Using power from the engine) actually has insanely specific be credible use case.
  
  It turns out that in very specific engine types, you can gain additional engine efficiency that’s worth the energy it took to generate the gas. The us army did a whole proper study. That net gain was, however, only present in vehicles not maintained on the usual schedule. So it did infact help some engine types that were not well maintained.
  
  I know this because I did a dive years back. Effeciency be damned, building a reserve of browns gas that I could dump in when I wanted for a power boost sounded fun as hell to me. You wouldn’t gain any effeciency (probably loose a ton) but you would have more power when you were mixing in the reserve you’d built up. I wound up not doing it because 1) the vehicle I had in mind was carb not fuel injection so no power gains there. And 2) dealing with generating, pressurizing, storing and delivering a gas isnt a ton of fun in a “for the lolz” project.

  It’s hard to say without reading the actual paper, but summaries (from other sites, the earth.com site is terribly lacking) describe their approach as an alternative substrate for hydroponic cultivation, which would be both easier/more eco-friendly to produce, and allow conductivity. In any case it is far from “sticking a metal stick around”.
  
  source
  - batmaniam@lemmy.world ⁨10⁩ ⁨months⁩ ago
    So I’m trying to find an academic article, but it’s not just the substrate. They blew right past it in the article but there is electric potential applied, and the substrate is slightly conductive which is what allows it. They seem to imply that leads to better root growth but like I said the article barley mentioned the actual e of the e soil lol.
    
    But bioelectrochemistry is a thing. I work on the other end, where microbes are depositing electrons, but I am aware of different technologies where the bugs use a potential as an energy source for specific reactions, usually around remidiating some nasty stuff in the ground.
    
    Im less aware of it affecting a plant directly (I’d assume it changed the soil bugs or something) but it’s not hard to picture. Good be something as simple as the potential changing the osmotic pressure and making it easier for the plants to take up nutrients or something.
    
    But yeah, pretty far from a rod in the ground, although in some cases that is basically all you’d need. The bioelectrochemistry field always had junk science to contend with.

I grow using a technique known as “notill” where you guessed it, I never till the soil. Or replace it. It’s organic, I even have helper bugs and worms. Inside. It’s awesome.

- douglasg14b@lemmy.world ⁨10⁩ ⁨months⁩ ago
  Don’t you have to till at least once?
  
  I tried growing on ground that was matted deep with thick, dead, vegetation. And even after raking the crap out of it and trying to dethatch it, I couldn’t get anything to stick.
  
  After giving it a good till and mixing in a decent bit of old herbivore manure, my plants would take and grow wonderfully.
  
  source
  - Pipoca@lemmy.world ⁨10⁩ ⁨months⁩ ago
    Nope. The idea in no till is just adding stuff to the top and letting worms and roots handle the tilling.
    
    I’ve had good luck just dumping a foot or two of finished compost on the ground and growing in it.
    
    Another solid no-till approach is sheet mulching. You put down a layer of cardboard (to kill weeds), then layers of carbon and nitrogen like straw and kitchen scraps. Wait a few months, then plant. So you could do that in the late summer or fall to prepare a site for spring planting.
    
    A lot of these things depend on location, though. Something that works great in Pennsylvania might not work as well in Utah.

If this allows growing trees inside, that’d be amazing. Imagine mango, banana, guava, and other exotic fruits being grown in the north or in vertical farms.

  This makes me miss a bar I used to go to, and was the favored watering hole for most of the staff at a previous job.
  
  It had had several owners, and it’s name changed on official paperwork every time. Locals still called it Big Tree.
  
  Why?
  
  It was built around a big tree that went out of the roof lol.
  
  It was bought and demolished, the tree removed.
  
  Nothing has been done with the lot since, and it’s been a couple years.
  
  Damn shame.

Humanity could already be well fed without stuff like genetic manipulation and eSoil. We have all the agricultural methods to produce enough food for everyone. Fair distribution is the actual challenge, not production.
