Factsheet: Greenhouse Gases and Soil Organic Carbon in Vegetable Production

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.

Soil Health 101 for Community Gardens -- A Bilingual Workshop

October 24, 2025
11:00 AM - 3:00 PM
Staten Island, NY

Join Urban Agriculture Specialists, Karen Guzman and Yolanda Gonzalez, as they discuss the importance of soil health and testing your soil as you prepare for the incoming growing season. They will go into strategies for best practices when it comes to soil health management and highlight the current soil testing program through NYSDAM and CCE. This workshop will be in both Spanish and English.

Biochar 101 for Community Gardens (Upper Manhattan)

October 25, 2025
1:00 PM - 4:00 PM
Upper Manhattan, NY

Join Karen Guzman and Dr. Rebecca Nelson of Cornell University, Bill Hilgendorf of White Feather Farm, and the NYRP Urban Ag team for a deep dive into biochar as a tool for waste management, carbon storage, and soil health in a community garden context. During this hands-on workshop, participants will have the chance to make biochar using garden waste and learn about best practices when applying it to a garden bed. Workshop attendees will all receive a small amount of biochar to take back to their garden.

Space is limited. Pre-registration required.

New York Urban Farms Sustainable Pest Management Fact Sheet Series

Cornell Cooperative Extension has partnered with dozens of urban farms across New York State to demonstrate and evaluate sustainable pest management strategies. Together with farmers, we found success using control methods that prevent or reduce crop losses through exclusion strategies, crop timing, host resistance, the introduction of beneficial organisms, and more. Regardless of management strategy used, common requirements for success include a knowledge of the pest and disease complex, preventative deployment and commitment to the process. The New York Urban Farms Sustainable Pest Management Fact Sheet Series includes case studies highlighting pest management techniques that New York urban farms have found valuable.
