BMP and CRP Workshop

Nutrient Management for Water Protection in Highly Productive Systems of the Heartland

June 8-10, 2010 - Nebraska City, NE

The Heartland Water Quality Coordination Initiative's Nutrient Management (NM) and Bioenergy and Water Resources (BWR) Teams hosted a "Nutrient Management for Water Protection in highly Productive Systems of the Heartland" Workshop. This workshop was held on June 8-10, 2010 at the Lied Lodge and Conference Center in Nebraska City, NE.

The Workshop consisted of 81 participants from IA, KS, MO, NE and WI. These participants included university researchers and state and federal agency personnel. The Heartland and NM team has hosted Workshops annually since 2004. Each of these workshops was preceded by a Winter Roundtable which was a smaller group of mainly researchers.

Intended Audience:

1. University and ARS research and extension faculty
2. State and federal agency personnel
3. Resource managers and advisors
4. Watershed and conservation groups

Workshop Goal:

To share current research, management and extension information related to nutrient management for water protection in highly productive systems with a climate change perspective.


1. Impact of Projected Climate Change on Nutrient Management
2. New Technologies to Improve Nutrient Management
3. Consequences of Crop Residue Removal on Soil and Water Quality
4. Setting Regulatory Controls for Nutrients
5. Managing Economic Impacts and Risks of Nutrient Management
