There's magazines like this one (https://www.agweb.com/farmjournal); however it sounds like we'd have different ideas of small though. Outside of direct to consumer farmers market type opperations, "small" farms in the US are still measured in thousands of acres (just, 4 figures instead of 6).

The meta markets in how and when you sell crops (pre sale on the futures market vs sale at harvest, vs store and wait for commodities prices to be ideal) is, honestly fascinating and so different from the image of the "farmer" in popular culture.
