CRAE special session on nitrogen management
2010. Recognizing the important role nitrogen plays in healthy farming systems and communities, CRAE members, along with twenty partners, gathered on April 15, 2010, to build a common base of knowledge about nitrogen management and California agriculture. Key scientists and regulators in the field shared their expertise with the group. Below, you will find the links to a set of presentations made during the session, which together provide an overview of the current state of knowledge on nitrogen science and management in California. CRAE members will be exploring agricultural nitrogen further in the coming months.

In connection with CRAE’s Special Session on Nitrogen Management, the following materials were submitted to amplify presentations made by experts.
- A one-page summary of the UC Davis Agricultural Sustainability Institute’s California Nitrogen Assessment.
- A summary of the research project Collaborative Research to Understand How to Reduce N2O Emissions from Nitrogen Land Application led by UC Davis and CSU Fresno researchers.
- Resources on public health impacts of nitrates: Information on the impacts of nitrates on drinking water has been compiled by the US EPA and the CA Department of Public Health. The State Water Board’s Groundwater Ambient Monitoring and Assessment (GAMA) Program also developed a series of maps indicating nitrate concentrations in groundwater over time, and a presentation by the CA Department of Public Health indicates nitrate effects on public water system wells.
