How to earn more money on a homestead?

My husband and I live on his family farm, there’s a total of 2,000 acres. We own a house we inherited and are mortgage free, our car is payed off, and we have 0 debt. We are making hardly any money on the farm right now, we can maybe save an extra 100 each month so NOTHING. Does anyone have advice on how to make more money on our homestead? I feel like we’re in a good situation to become wealthy but we do not know how to start.

Please help!
