The artificial drainage of Minnesota’s agricultural land has increased over the past several decades, with profound costs to the quality of our lakes and streams, fish and aquatic species, recreation, and downstream infrastructure. Beginning around the mid-1970s, corn and soybeans, which require relatively dry soil conditions to thrive, became dominant crops among Minnesota growers.

Because Minnesota was naturally home to many wetlands, prairie potholes, and low-lying saturated areas, farmers needed to drain their fields to achieve dry soil conditions. As a result, many agricultural fields in Minnesota are now underlain by perforated plastic pipes (referred to as “drain tile”), which collect and deliver water to public and private ditches and ultimately to our lakes, rivers, and streams.
