Not trying to be argumentative but I know farming very well. My family has been in farming for six generations. Most of the productivity improvements in farming were crop yield and equipment improvements. Both heavily R&D based. Corn yields have gone from about 50 bpa to over 125 bpa since 1960. We used to farm (excluding livestock0 1,000 acres with 4 men and 2 part timers in the late 60’s. Now the family farms 5,000 acres with 4 men and incredibly expensive equipment that is light years ahead of equipment even 20 years ago. “Services" imho play(ed) only a small part in the productivity while R&D based improvements made the biggest gains in productivity.

Yeah, I know. Was raised on a cattle ranch, then later my stepfather was a farmer.
