CARBON SPONGE NETWORK
Carbon Sponge has been building networks of carbon farmers since 2020. We first formed an Affiliates group in 2020 in New York City and more recently a Carbon Sponge Hub at White Feather Farm, Saugerties, NY, in 2022 for small-scale farmers in the Hudson Valley and Catskills regions.
The Carbon Sponge Hub @ White Feather Farm started in 2022 with six small farms in Hudson Valley and the Catskills: Foxtrot Farm and Flowers, Mossy Stone Farm, Newton Farm, Nimble Roots Farm, White Feather Farm and Zena Farmstead.
In 2023, we expanded to 10 farms with: Bonhomie Farm, Stoneberry Farm, Sweet Freedom Farm and The Lo Farm.
In 2024, with support from Northeast SARE and The Spark of Hudson, we are focusing on 5 farms (returning and new members) with the goals of scaling up sorghum production, experimenting with culinary uses for sorghum harvest and verifying our Kit for field testing in collaboration with the Cary Institute of Ecosystm Studies. The five farms are: White Feather Farm, Nimble Roots Farm, Sweet Freedom Farm, Foxtrot Flowers and Farm and Coming Home Seeds.
Since 2021, we have developed protocols specific to the Hudson Valley and Catskills farming community to build and cultivate experimental plots (one at each location) for studying carbon storage in agricultural fields. Throughout the season we have been tracking, analyzing, sharing and discussing data from the Kit coupled with professional laboratory testing.

We are focusing on growing sorghum in the Hub’s experimental plots since 2022 for a couple of reasons. Most of the Hub farms were unfamiliar with sorghum and it is not a common crop in the region. Carbon Sponge has been growing sorghum in NYC as part of its cover mix since 2018 and since 2019 has been testing The Land Institute’s perennial breed.
Sorghum is a grain originally from East Africa that is resilient in heat, drought, floods, and various soil types (including nutrient-poor and contaminated). The plant has incredible biomass and deep roots, terrific characteristics for carbon storage. The plant is a stunner – it litearlly stops people in their tracks. Lastly, sorghum is known to accumulate silica in its tissue that can bind with carbon to stabilize it.
Harvesting the sorghum for grain and/or syrup while returning the rest of the biomass to the ground allows us to feed the soil and our communities at the same time.

Carbon Sponge Affiliates in NYC was active for two seasons (2020-2021). The group included: Bronx River Foodway (Bronx), GrowNYC Teaching Garden (Governor’s Island), NYU’s Urban Farm Project (Manhattan), Pioneer Works (Brooklyn), and Prospect Farm (Brooklyn) and Red Hook Farms (Brooklyn). Over the two years, the Affiliates members in NYC tested the Carbon Sponge Kit and data collection protocols in their existing green spaces, discussed ecological farming practices as they pertain to an urban context, and analyzed results together.
