2017monlocs.jpgEdge-of-field (EOF) monitoring projects are designed to collect accurate measurements of sediment, nitrogen and phosphorus movement over the soil surface and through subsurface drainage tiles. This work leads to a better understanding of the relationship between agricultural management and water quality.


Edge-of-Field monitoring began in Minnesota in 1997 with three sites as a part of the Red Top Tile Drainage Demonstration. Since then, EOF monitoring has been conducted as a part of seven unique projects:

The MDA along with cooperators and partners, is responsible for installing and maintaining equipment to collect water quality, flow, meteorological and other project specific data.

Number of Monitoring Sites

  • Since 2009, MDA has increased the number of EOF monitoring sites from 7 to 38 sites
  • Monitoring sites stretch across the different types of agricultural areas of Minnesota


The graph displays the average monthly sediment losses (lb/acre) and precipitation (inches) for all four Root River Field to Stream Partnership EOF surface water monitoring sites from 2010-2016.

The collection of this data provides a useful tool to help inform the public and work with landowners to reduce nutrient and sediment pollution.
