The North Central Region Soil Health Nexus was initiated in 2016 with funding from the North Central Region Water Network. A North Central Soil Health Work Group with representatives from Land Grant Universities across the 12 state region convened to address the challenges of increasing access to soil health research, knowledge, extension and resources. A regional structure was initiated around the three areas of Research, Extension and Outreach, and Resources and Communications. The Nexus/MaSH interactive website serves the communication conduit for each area.

Setbacks Reduce the Concentration of Manure Constituents in Runoff

What setback distance is required to reduce the concentration of manure constituents in runoff to background values? John E. Gilley, Aaron J. Sindelar, and Bryan L. Woodbury, researchers with the USDA-Agricultural Research Service, examined the effects of setback distance on concentrations of selected constituents in runoff following land application of beef cattle manure to a site in Southeast Nebraska (Figure 1).  Continue reading

While using sand laden manure as a fertilizer source does add sand to the soil, the change is small and would take about 100 years for a silt loam soil to see a change in soil texture.
