Impact of Agricultural Drainage in Minnesota

Glacial processes in the Upper Midwest created an abundance of highly productive but poorly drained soils. While it’s improved agricultural production, drainage also affects hydrology, water quality and wetland habitats.
Improved agricultural production: Poorly drained soils increase risks to agricultural production from excess water and high water tables. Proper soil drainage improves agricultural production by: Ensuring timely planting and field operations.
Minimizing soil compaction and salt buildup.
Promoting conditions for good seedbed establishment and germination.
Minimizing high water table stresses to growing crops.
Out yielding poorly drained soils
Offering less year-to-year yield variability.
Improving the opportunity to employ other conservation practices such as minimum tillage.
