It's public knowledge, but they won't tell you on RFD TV. Not with all
their advertising revenue depending on Monsanto, John Deere, ADM, etc.
It's well known that the virgin soils of this country were incredibly
productive when they first broke sod, like the grassland prairies of the
midwest. It's also well known that the use of chemicals has greatly
increased since WW II, and they're still increasing while productivity is
not. Anyone have figures to the contrary? Actually the U.S. turned into a
net IMporter of food a year or two ago.
