It’s agriculture, there’s always profit.
https://en.wikipedia.org/wiki/David_Brandt_(farmer)
In the late 1990s and early 2000s, Brandt experimented with different combinations and species of cover crops, such as radishes and sunflowers, to improve crop yield and improve soil quality. As a result of these cover crops, Brandt was able to cut back on commercial nitrogen additives, which also saved money. Additionally, Brandt saw less mold and blight and fewer insects among his crops, to the point that he was able to reduce or stop using fungicide, herbicide, and insecticide on parts of the farm.
yep absolutely no hand-harvested crops, just unheard of, nobody makes any money farming those
