I think subsidies are a good thing, however our current application of them is definitely backwards. Corn is one of the worst crops to subsidize, the whole reason we grow corn is because how absolutely robust and resilient it is as staple crop. However the trade off for being such a strong crop is poor input-output efficiency. I think subsidies need to be applied to more vulnerable crops, some should go to staple crops other than corn, but I think the larger portion of it should go to fruit and vegetable production. I would also like to see some of it given to more sustainable farming practices, with an emphasis in reducing artificial irrigation, reducing artificial fertilizer usage, and maintaining or increasing topsoil depth and soil health, although I have no idea how to properly implement those practice.

When you grow a crop that takes nutrients out of the soil they must be replaced. When you eat the crop in the same location (substance farming) there isn't a problem as your excrement is fertilizer.

When you live in the city that doesn't happen - nobody transports sewage back to the fields. It isn't necessarily a good idea to try: the energy to transport sewage back to the fields needs to come from somewhere; sewage needs to not have harmful chemicals/heavy metals from other processes mixed in.
