This project combines the use of automated soil moisture probes for irrigation scheduling with diverse cover crop planting to reduce or eliminate leaching of nitrogen and other nutrients on cropland with an early season harvested crop in the rotation. The more efficient use of irrigation waters provides a secondary benefit: less withdrawal from the aquifers that provide recharge for the Mt. Simon-Hinckley aquifer.
The Cannon River is a designated Wild and Scenic River that originates in Rice County and joins the Mississippi River 120 miles downstream near Red Wing. The Upper Cannon, which encompasses 29% of the entire watershed, has been identified as a priority subwatershed.
