the whole efficient markets argument requires pressure in both directions. no one is short selling farmers.
just like how if a house is overpriced and real estate investors believe it that doesn't mean there's going to be adequate downward pressure (in expectation) to prevent an unlucky family from overpaying on the house. (there is upward pressure, though, because of house flipping)
and since entry into the agriculture industry is pretty steep, it's not like anyone who has an idea can just build a farm with a cool robust idea that is more optimal than the current solution.
the other difficulty is the extensive time horizons to implement the solution suggested by hosh. farmers can't just drop everything they're doing this season, implement regenerative ag ideas today and reap the benefits come harvest this year.
it's the same issue with organic. transitioning to organic is a time and cost intensive process for farmers (it can take a few years to be fully certified). only a small percentage of farms produce organic even though it commands a higher price.
