The short answer is significantly negatively.
The problem with farming is that all the money is in the last few bushels and acres. Of course, these numbers change from year to year depending on input prices and crop prices, but the first 60%, 70% or 80% goes straight to creditors.
You have pay for equipment loans. You have to pay for crop inputs. It's those last few bushels an acre that go straight into the farmer's bank account. A reduction in yields would be a disaster.
