Because a non-profit in the US just means that they can't distribute profits to the shareholders, not that they can't try to make money. They just need to use their profits to further their mission instead of distributing to shareholders. For example, the Gates Foundation could own a completely conventional farm, and run it like a conventional farm, but any profits they generate could be used to buy and deliver malaria pills to at-need countries (or something like that). That would be an acceptable reason a non-profit owns farmland.
