The Panhandle Ag e-News from Florida had an interesting article about the production of rice in Florida, which is increasing although it is still a small crop.  According to the article, rice has been grown in southern Florida for the lat 60 years, but is now being grown as a cover crop in rotation with sugar cane.  In the future, production may increase due to the relative abundance of water in the Southeast and the reduction in crop growth in other areas where droughts are becoming more frequent.  You can read about it and watch a short video at https://nwdistrict.ifas.ufl.edu/phag/2016/11/04/rice-production-in-florida-a-minor-yet-uniquely-valuable-crop/.
