Rice fields in some counties are “underwater “due to the excessive rain in the last days of June.  As I drove (07/02/14) in Monroe, Woodruff, and St. Francis Counties, I saw fields of soybean and rice covered with water (Pictures 1, 2, 3, 4).  Information on soybean conditions has been given at http://www.arkansas-crops.com/2014/07/02/flooded-replanting-considerations/. Though not […]
