Why the Concern about Nitrous Oxide Emissions?

Join eOrganic for a 2-part webinar series about a current USDA-NIFA funded research project: Greenhouse Gas Emissions and Soil Quality in Long-term Integrated and Transitional Reduced Tillage Organic Systems. The first webinar will take place on February 25, 2014, and the second will take place on February 27, 2014. Both presentations will be at 2PM Eastern Time (1PM Central, 12PM Mountain, 11AM Pacific Time). They will each last 45 minutes, followed by a 30 minute question and answer session. Audience members can type in questions which will be read aloud to the speakers. The webinars are free and open to the public, and advance registration is required.

Presenters: Ann-Marie Fortuna, North Dakota State University; Craig Cogger and Doug Collins, Washington State University-Puyallup

Webinar 1: Why the Concern about Nitrous Oxide Emissions?

February 25, 2014 at 2PM Eastern Time (1PM Central, 12PM Mountain, 11AM Pacific Time)

Register for Webinar 1 at https://www1.gotomeeting.com/register/858663529

Topics for this webinar include:

  • Source and properties of N2O as a greenhouse gas, its relative contribution to global
  • warming, and the role of agriculture in N2O emissions
  • Review of the nitrogen cycle and the production of N2O
  • The relationship between organic practices and N2O production
  • How we measure N2O emissions

Intended audience is extension faculty and farmers who want a big picture perspective on why we’re interested in nitrous oxide emissions.

Webinar 2: Management to Reduce N2O Emissions in Organic Vegetable Production Systems

February 27, 2014 at 2PM Eastern Time (1PM Central, 12PM Mountain, 11AM Pacific Time)

Register for Webinar 2 at https://www1.gotomeeting.com/register/697821457

This is the focus of our current research. How do different organic vegetable production systems affect N2O emissions, and how do other outcomes of those systems affect theirpotential for adoption?

  • Systems include full tillage with high-carbon amendment (compost), full tillage with low carbon amendment (broiler litter), pasture-vegetable rotation, and reduced tillage cover crop mulch.
  • Measurements include N2O and CO2 emissions, soil N, microbial ecology focused on denitrification organisms, crop yield, and soil quality. Measurements are focused on key times during the season, including amendment application and tillage, irrigation, and freeze-thaw.

Intended audience is other researchers, and interested extension faculty and farmers.

About the Extension Foundation

The Extension Foundation was formed in 2006 by Extension Directors and Administrators. Today, the Foundation partners with Cooperative Extension through liaison roles and a formal plan of work with the Extension Committee on Organization and Policy (ECOP) to increase system capacity while providing programmatic services, and helping Extension programs scale and investigate new methods and models for implementing programs. The Foundation provides professional development to Cooperative Extension professionals and offers exclusive services to its members. In 2020 and 2021, the Extension Foundation has awarded 85% of its direct funding back to the Cooperative Extension System, 100% of funds are used to support Cooperative Extension initiatives. 

This technology is supported in part by New Technologies for Agriculture Extension grant no. 2020-41595-30123 from the USDA National Institute of Food and Agriculture and membership funding.
