Open field farming will always be preferable because natural soils contain hundreds if not thousands different micro-nutrients that are not defined. Just like chicken or hogs confined to facilities and only fed processed feed that cannot possibly replicate a natural diet, what will be the long term effect on us?
If the past is prologue, we should all live longer and less painful lives.
This is a good thing. Increased agricultural production helps the entire planet. This type of system would also be useful for deep space exploration.
