Won't yields go down eventually as the soil becomes more and more degraded as the same nutrients are extracted? I'm assuming you need to find a way to make up

I'm assuming you need to find a way to make up for that. Something that's hard to do if you think about how grain is planted. Can't really drive over it with a tractor once it has a certain height. Even if you take off only the parts you need and leave the rest in place.
- hnmullany 4y agoYou still need to add fertilizers that's not what this is about. (And you absolutely drive over crops with tractors)
- tfourb 4y agoPerennial plants are much more effective at extracting nutrients because of more established root systems. Not tilling the field also allows for complex plant/fungi communities to develop which will increase moisture and nutrient levels in the soil. Put simply: you don’t need to fertilize a forest or other naturally occurring ecosystems and those are built around perennial plants. The closer you get back to a functioning ecosystem, the less reliant you’ll be on external inputs.
