PROJECT GOAL: Improve agricultural production and reduce flooding losses while minimizing the unwanted environmental impacts of subsurface drainage.
PROJECT OBJECTIVE: Demonstrate controlled tile drainage as a flood mitigation practice as well as the water quality and quantity benefits. The project is intended to set an example to increase the adoption of drainage water management practices in the Red River Valley.
Project partners are evaluating drainage water management on operating farms in the Red River Valley. Additional information, including study design and monitoring results, can be found in the project factsheet below.
What is DWM?
Drainage water management (DWM) or controlled drainage, helps producers manage water on their fields. This practice can increase crop production, keep nutrients on the field and send cleaner water downstream.
Producers control the water by raising or lowering the elevation of underground drainage. Water can temporarily be held back within the root zone for later use by the crop or it can be released to drain the field for planting.
Why the Red River Valley?
The Red River Valley, in northwestern Minnesota, has experienced an increasing amount of subsurface (tile) drain installation. Subsurface drainage is common in other areas of the state, however it is becoming more widespread in this region. This project allows regional farmers to see how DWM works in their own "backyard".
