ecmn | It's the system. It's not one individual thing..
Back then very highly likely there was some sort of livestock on the farm
Also, more likely they had more crop rotation, even set aside or green fallow or green manure crop. Whatever you want to call it
They also did tillage a lot more shallow. There's a huge difference between pulling a plow at 6 in deep rolling under manure and probably a hay crop or alfalfa or something green and growing versus a disc ripper behind soybean stubble.
Biology is the difference, and the plow amplifies it. You got dead non-functioning dirt. You plow it. You're going to have dead non-functioning dirt. You've got biologically active soil and you plow down a lot of carbon. You will amplify it | |

Does soil get worked down finer now than it did 15-20 years ago?
