 Goals: Uniform field conditions for timely planting and harvesting Higher crop yields Risk reduction

Do we have the technology we need to do effective drainage water management?

 Production AND Environmental Benefits – this impacts the scale (field vs landscape)  Drain only as much as needed  Get rid of the water OR keep it  Storage and re-use  Water treatment / filtration  Flood attenuation  Watershed planning  Managing surface drainage water

 Lidar – water management design applications  RTK-GPS – controlled traffic  Bioreactors  Saturated buffers  Treatment wetlands  Two-stage ditches  Subirrigation  Crop genetics – improved stress tolerance

 Telemetry for control  Subsurface drainage system design software that optimizes water management zones  Control ‘valves’ for surface inlets  Simple accurate flow measurement – critical for nutrient trading verification

 Suites of practices are critical  Controlled traffic  No till  Cover crops  4 R
