As the name suggests, drainage water management helps producers manage water on their fields by controlling water discharges from surface and/or subsurface agricultural drainage systems. This practice can increase production, keep nutrients on the field and send clean, filtered water downstream.
Purposes and Benefits
Reduce nutrient, pathogen, and/or pesticide loading from drainage systems into downstream receiving waters
Improve productivity, health, and vigor of plants
Reduce oxidation of organic matter in soils
Reduce wind erosion or particulate matter (dust) emissions
Provide seasonal wildlife habitat
What is Drainage Water Management (DWM)?
Drainage water management is the process of managing the timing and the amount of water discharged from agricultural drainage systems. DWM is based on the premise that the same drainage intensity is not required at all times during the year. With DWM, both water quality improvement and production benefits are possible. Water quality benefits are derived by minimizing unnecessary tile drainage, reducing the amount of nitrate that leaves farm fields. DWM systems can also retain water in fields that could be used for crop production later in the season.
Where does DWM work?
The flatter the topography, the better
The more intensive the tile system, the better
To be cost-effective, fields should be 20 acres or more in size
Ground Disturbing Potential of Conservation Practices
This is a potential ground disturbing conservation practice. Any project with ground disturbing or potential ground disturbing practices planned may need to be submitted for review by the State Historic Preservation Officer and Tribal Historic Preservation Officers. Please see the Cultural Resources Review Process Flowchart for an outline of this process. View a list of conservation practices used in New York State, and their ground disturbing potential.
