This land is rented out foe farming. Local FArmer, not a big business. Is this a QBI?

Probably not. It isn't a business, it is passive income and you may not be very involved. If this is true, it is not QBI.

In the Learn More - it states:  If you are renting property that requires very infrequent interaction with the tenants and maintenance to the property, the courts have generally found this type of activity is not a "trade or business".
