Long-term C and N2O monitoring and climate-smart management of organic grain production systems
- Research Topic: Fertility/Climate/Environment / New
- Back to Project Listing
The project aims to expand knowledge of greenhouse gases (GHGs) in organic production by measuring N2O emissions and soil carbon storage for wheat, oat and flax grown in a variety of organic production scenarios.
Objectives are to: 1) Compare organic and conventional production in terms of N2O emissions over a growing season. 2) Compare organic and conventional production in terms of soil C storage over the long-term (32 years). 3) Determine the GHG footprints of organic wheat, oats and flax compared with conventional production. 4) Evaluate how mixing legume green manure cover crops with non-legume plant species affects N2O emission during and after the green manure phase. 5) Evaluate how reducing tillage in the legume green manure cover crop termination phase affects N2O and ammonia emissions after legume termination. 6) Determine if fall cereals reduce the post-termination N2O emissions from alfalfa hay crops.
