Carbon cycles and farming


OUR Research

These are the questions that drive us.

Hudson Carbon is working towards developing a greater understanding of how carbon cycles through an agricultural ecosystem, and how farm management affects this cycle. With this greater understanding, we aim to offer farmers and land managers sound data demonstrating the effectiveness of different practices in building and sequestering carbon in the soil long-term.


We began this project with a hypothesis: that the implementation of particular agricultural management practices could facilitate the buildup of organic carbon within the soil over time. These practices include cover-cropping, reducing overall tillage, organic nutrient management, diversification of rotation, livestock integration, and Keyline plowing, among others.


In 2015, Hudson Carbon established 12 testing sites at two farms in the Hudson Valley, and established sites on a third farm in 2018. Stone House Farm, our closest farm partner, is a certified organic, integrated cropping-grazing operation on 2,500 acres. There are nine testing sites at Stone House Farm, located in fields that are at various points within a broad cropping and grazing rotation. At Churchtown Dairy, a 250-acre biodynamic dairy, we have three testing sites in pastures that are under intensive grazing management.


Throughout the growing season, we gather data at key points within the carbon cycle on these testing sites. We gather soil samples to a depth of one meter, we gather plant biomass and surface litter, and, using a portable greenhouse gas analyzer in the field, we can also measure the flux of carbon dioxide, methane, and nitrous oxide in and around the plant canopy. With data gathered in the field, we perform testing in our lab to measure the carbon content within the soil, plant biomass and surface litter. With the data gathered from these various sites, we accurately measure the carbon cycle within these farming systems, and demonstrate the change in soil carbon content at each testing site over time. We generate a carbon cycle timeline for each field, and draw correlations between certain agricultural tasks and the flux of carbon on that site. Over time we can then accurately measure the carbon footprint of the farm as a whole, demonstrating the ability of these farming systems to extract carbon dioxide from the atmosphere and store it in the soil.
