Factsheet: Greenhouse Gases and Soil Organic Carbon in Vegetable Production

December 15, 2022

The intersection of agricultural production and greenhouse gases is gathering increasing attention. This is an opportune time to consider how vegetable production interacts with carbon sequestration and greenhouse gas emissions, and how using cover crops may alter this picture.
The factsheet, Greenhouse Gases and Soil Organic Carbon in Vegetable Production and the Role of Cover Crops, discusses:
- Sequestration of atmospheric carbon in agricultural soils as soil organic carbon (SOC). Is vegetable production impacting SOC?
- Net greenhouse gas emissions of carbon dioxide (CO2), nitrous oxide (N2O), and methane (CH4) from the soil.
- Impact of cover crops on soil organic carbon, nitrous oxide emissions, and other GHG emissions.
This factsheet was written by Zach Spangler, CCE Harvest NY Ag Climate Resiliency Specialist, and Elizabeth Buck, CCE Cornell Vegetable Program Fresh Market Specialist.

Join us for a hands-on field day exploring integrated pest management and season extension tools for urban growing spaces and the opportunity to build community with local growers!This event will focus on best practices for using row covers and rat mitigation. Check out our CCE demonstration trial using insect exclusion netting to manage swede midge, an invasive fly that causes damage to brassica crops. Explore how to identify rat activity, reduce attractants, and strengthen site management. Hear from local growers on how they manage pests with a focus on organic management and how they extend the season on their farms and gardens.
Resilient Gardens Conference
September 18 - September 19, 2026
Fri: 9:00 am - 5:00 pm; Sat: 9:00 am - 1:00 pm
Poughkeepsie, NY
The third Resilient Gardens Conference will focus on culturally relevant gardening skills and community garden management for the unique resource needs of urban gardeners. This two-day event will feature education and practical skills on day one; we'll hear from leaders of diverse stakeholder groups on strategies to overcome these issues in cities and rural communities and connecting resources between Cornell Cooperative Extension and leading community gardens. The second day is optional and will include tours of local gardening projects across Poughkeepsie and Kingston NY. This event is primarily open to Seed to Supper Garden Educators, CCE Educators, Master Gardener Volunteers and Upstate Seed to Supper Program Participants, as well as partner Community Gardens involved with Harvest NY.
