Do you see any weeds in and around those rice plants?
Modern rice production in Arkansas and Mississippi is complex, but easy to understand. Rice is generally seeded on dry land after ground leveling. Since most fields are not flat or slopping the correct way, fields are often levelled.
Many times to aid the rice flooding and eventual water drainage, fields have levees that allow water to flood and drain at appropriate times. Often times these levees are not in straight lines and are called contour levees due to following slightly different elevations in the field. Once the rice is near maturity, the water is drained and is harvested with a combine.
