Management to Reduce N2O Emissions in Organic Vegetable Production Systems

Cogger, C., A. Fortuna, D. Collins. Feb 27, 2014. The second of a two-part webinar series on Greenhouse Gas Emissions and Soil Quality in Long-term Integrated and Transitional Reduced Tillage Organic Systems.

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 their potential 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.

Why the Concern about Nitrous Oxide Emissions?

Cogger, C., A. Fortuna, D. Collins. Feb 25, 2014. The first of a two-part webinar series on Greenhouse Gas Emissions and Soil Quality in Long-term Integrated and Transitional Reduced Tillage Organic Systems.

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.

Integrating Livestock into Dryland Organic Crop Rotations

Carpenter-Boggs, L., Painter, K., and Wachter, J. Recorded webinar presentation delivered October 22, 2013.  It covers a variety of reasons to integrate livestock into crop rotations, and summarizes past research on the topic. It is directed towards beginning growers interested in diversifying their income and crop rotations, towards educators and Extension workers, and towards a more general audience wanting to learn more about mixed crop-livestock systems.

Dryland Organic Agriculture in the PNW: Meeting Opportunities and Challenges

At the Tilth Producers of Washington Conference in November 2011, WSU hosted a Dryland Organic Agriculture Symposium. The presentations and keynote from that symposium were recorded and are now available for online viewing. This special symposium addressed agronomic and economic issues specific to dryland organic production.  Speakers and attendees came from Washington, Oregon, Idaho, and Montana. Also, please see link for a list of companies interested in buying organic crops produced in the PNW: Dryland Organic Agriculture in the PNW – grains sellers buyers
