Obviously it’s not just one field that you use again and again. All you need to do to replenish the nutrients in the field is to just let it hang out and don’t do anything with it for a while, and use some other areas in the meantime.
Much, much more stable, renewable and reliable than aeroponics. It’s a cool concept but it’s just nowhere near at the level of competing with good ol fashioned dirt yet!
Absolute nonsense, sorry. Horizontal farming is more than capable of feeding everyone on earth today, and could sustain a population even ten times what we currently have - we’d need to give up meat, of course - which we should be doing anyways.
I mean, it will eventually - it might take a while, sure, but there’s so much land, and with sustainable farming practices (good crop rotation, organic farming, etc.) then soil erosion and nutrient depletion are significantly reduced anyways. It’s definitely much, much easier and significantly less reliant on synthetic nutrients than hydroponics or aeroponics. A lot less work, too!
