Poor humidity, rain and heat in 2016 cut rice yields in Craighead County, Arkansas, to about 120 bushels per acre from a typical 180. Local extension estimates up to 5% of the county's roughly 200 farmers could exit farming.
Lower regional rice, soybean and corn output is a small supply tightening at the margin. Overall US supply is much larger, so the price effect is limited.
