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.
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.
