Why do producers continue to add more drainage (increase intensity)?
Goals:Uniform field conditions for timely planting and harvesting
Higher crop yields
Risk reduction
Modern Drainage Technology
WE HAVE THE TECHNOLOGY TO DRAIN EFFECTIVELY
Do we have the technology we need to do effective drainage
water management?
Is this technology sufficient?
What is the goal 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
Some potentially useful emerging technologies
Lidar – water management design applications
RTK-GPS – controlled traffic Bioreactors Saturated buffers Treatment wetlands Two-stage ditches Subirrigation Crop genetics – improved stress tolerance
Needed technologies 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
No silver bullet Suites of practices are critical
Controlled traffic No till Cover crops 4 R
