Sauk River Waste Management Project

This project consisted of an earthen basin lined with a HDPE liner and a concrete stacking slab. The runoff from the feedlot flowed to a waterway that emptied into a tributary of the Sauk River. The earthen basin collects the feedlot runoff so those nutrients do not enter waters of the state. That water is applied through the irrigation system. The concrete stacking slab will store solid manure from the feedlot. This manure is applied to the cropland at agronomic rates to better utilize these nutrients. The crop rotation

is a corn/soybean/alfalfa/small grain rotation. The landowners are also experimenting using cover crops as a nutrient source while helping to control erosion in their cropland.

Components:

• Earthen Basin

• Stacking Slab

• HPDE Liner

Benefits:

• Pollution Reduction

• Improve Water Quality

• Environmentally Sound and Efficient Application of Manure

• Sustain the Agriculture Industry

Pollution Reduction Estimates:

• Phosphorus: 41 lbs./yr

• COD: 2,975 lbs./yr

• BOD5: 661 lbs./yr

• Nitrogen: 156 lbs./yr

The partners on this project included the landowner, Stearns CD, MN Department of Agriculture, NRCS, and the Sauk River Watershed District.
