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.

Anaerobic Digestion

CSANR webpage.  Anaerobic digestion (AD) is a process in which organic matter is converted into methane by bacteria in the absence of oxygen. Under typical dairy farm conditions manure is stored in open ponds and applied to fields, where decomposition often occurs under anaerobic conditions. This leads to the natural, open-air production of methane, a greenhouse gas with more than 20 times the warming value of carbon dioxide. By enclosing, controlling and accelerating this natural anaerobic conversion process, not only can the methane be contained, but it can be converted to renewable energy, providing two mechanisms for carbon sequestration and global warming reduction – methane capture/conversion and fossil-fuel energy offset.
