Much of the most productive cropland in the Great Lakes Region has been improved with subsurface tile drains. Research results and on-farm observation has shown that while conservation tillage reduces runoff, nutrient-enriched water from rainfall, snowmelt and other sources can quickly enter subsurface drains by preferential flow through macro pores ‒ large, continuous openings in the soil formed by plant roots, soil fauna, cracks, fissures and other natural phenomena. Soils under no-till crop management often have more continuous macro pores than tilled soils.
