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 lack of sewage treatment in many small communities in Southeast Minnesota is causing surface water and groundwater pollution. Ten of these small communities will be the target of the technical assistance provided by this project. These communities have community or individual straight pipes which are discharging raw sewage directly into the environment, surfacing sewage, or have sewage contaminating groundwater.
