Farmers say heavy rains that hit Arkansas in the past week have halted schedules for the soybean, rice and cotton harvests. Bill Robertson, a cotton specialist with the Arkansas Cooperation Extension Service, says the cloudy and cool weather has halted the development of the cotton crop. Robertson says many cotton farmers were aiming to put insecticide on their almost-harvestable crops this week. But they`ll have to push it back because of the rain. Robertson says some cotton farmers would like to start harvesting next week. Other experts say flooding from recent heavy rains has affected soybean farmers in far northern and southern Arkansas. They say high water is interfering with the harvest in the southern part of the state. The rains are keeping rice farmers out of the fields as well.
