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.

Organic Farming Systems

In 2003 an organic vegetable production systems experiment was established on organically certified research land at WSU Puyallup. The experiment compares 12 organic management systems, including three cover cropping systems, 2 tillage treatments, and 2 amendment types, arranged in a split-split plot design.
