This, like most technical innovations in farming, has the problem that most farms are extremely cash/investment starved.
Basically anything that primarily benefits small farms and the environment doesn't give sufficient return of investment for farmers to be able to borrow money for it, and they themselves have all their assets already fixed in expensive other farm equipment.
So the only ones that can benefit from this are the huge industrial farms with big corporate owners, and their (only) interest is to use it to cut labour costs.
