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
Waaaater sucks it really really sucks
Gaaatoooraaaaaid!
It's full of electrolytes. Plants need electrolytes.
Amazing movie!

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/aeroponic 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 water and the increase in growth rate.
There is a reason why the best weed is grown via hydroponic/aeroponic.
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 one of the top things to consider when it comes to farming on a massive scale.
This is so false it's not even funny. Hydro is way more efficient and aero even more so.
With farming indoors you can control the day/night cycle which not only increases the growth rate it also let's you manipulate fruiting and flowering.
Hydro and aero use a fraction of the water dirt farming does. More water is being taken up by the plants and none of it is being lost to the environment. On top of that evaporation is controlled so less is lost that way.
As mentioned above the growth rate is increased not only by the light cycle but also by being able to more strictly control and fine tune the amount of fertilizer and you use way less of it. Just like the water, fertilizer isn't lost to the environment.
Seems like some of you need to learn more about this stuff. There is a growing number of vertical farms popping up all over the world. Hopefully one day soon we will be buying lettuce, carrots, etc that were grown if not in the same building but on the same block.
If that was the case, why isn't every industrial farm doing it?
In part because traditional farms scale better than aeroponics or hydroponics. In part because farms don't pay for the environmental damage they cause. Because of these two points, there is little incentive to industrialize aeroponics or hydroponics.
What is true right now is that traditional farms use more water, fertilizer, and space, cause more environmental damage, but require less labor. And the labor problem can be mitigated with robotics, if we're willing to invest in that.
fertilizer
Or you could save $62,000/year by letting the mycorrhizal fungi and bacteria do their job.
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.
It doesn't actually take that much juice these days. On top of being able to use solar and wind generated power we also have leds that barely use any electricity to run.
Aside from the initial investment for the setup, the ongoing energy and resources needed for hydro and aero are most definitely going to be less than dirt farming especially when you factor in being able to grow year round. And don't forget the reduced amount of fertilizer and water usage. The water isn't lost to the ground with only a small amount of it being used by the plants.
Basically this is like ev versus ice. When you don't factor in everything, one looks better than the other but with all things considered, ev is way better than ice.
being able to grow year round
You can grow year round with low-tunnels (conduit and greenhouse plastic).
The best weed is grown in no-till soil, hence why living soil weed sells for more money.
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.
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.
which is really only a useful technology in places that are short on arible landq
So, everywhere within the next 60 years?
:-(
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).
People will do anything to avoid composting.
I don't understand why. It's a great way to get rid of your victims.
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".
Robert Pickton, is that you?
I might try that next time.
(it's from a movie)
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 as another idiotic experiment although the least crazy one. Could they 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".
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.
It's really weird to me that you write just like Jesse talks on the No Till Growers youtube channel
This is a most excellent place for technology news and articles.
