Why Carbon Farming?
Aldo Leopold defined soil fertility as the “ability of the soil to receive, store and release energy;” it is hard to conceive of a more succinct definition of “soil health.”
Recognizing that carbon is the energy currency of living systems –as the medium through which solar energy enters and radiates throughout the food web and the farm system– carbon farming focuses on opportunities for increasing the capacity of the farm system to “receive, store and release” that energy; as work, as system processes, and as biological and structural diversity within the farm ecosystem, particularly recognizing the critical role of soil organic matter as both a sink for solar energy and as driver of both soil and overall agroecosystem dynamics.
Carbon Farming is thus an explicit framework for engaging with the agroecosystem processes that drive system change. C-farming explicitly recognizes that it is solar energy that drives farm ecosystem dynamics and that carbon is the carrier of that energy within the farm system. Carbon farming is synonymous with the term ”regenerative agriculture,” when that term is explicitly rooted in an understanding of the underlying system dynamics and positive feedback processes that actually make a “regenerative” upward spiral of soil fertility and farm productivity possible (see figure, Lal 2015).
What is Carbon Farming?
Agriculture is one of the few human enterprises that has the ability to be transformed from a net emitter of carbon dioxide (CO2) to a net sink of CO2. Common agricultural practices, including driving a tractor, tilling the soil, and use of fossil fuel based fertilizers, pesticides and herbicides, result in significant CO2 releases. Alternatively, carbon can be beneficially stored long term (decades to centuries or more) in soils and perennial vegetation in a process called carbon sequestration. Read more on the Carbon Cycle
Carbon farming is successful when carbon gains resulting from enhanced land management and/or conservation practices exceed carbon losses.
CCI’s Carbon Farming framework is now widely supported by local, state, and federal natural resource agencies, and is providing a foundation for value-added direct marketing, sustainable supply-chain creation, and other corporate sustainability initiatives. Most importantly, carbon farming makes sense to farmers and ranchers, and has been an excellent vehicle for increasing on-farm climate and carbon cycle literacy.
Carbon Farm Planning
CCI has designed a process to develop Carbon Farm Plans (CFPs), combining whole-farm planning and resource assessment in a comprehensive planning framework. Carbon Farming is a whole farm approach to optimizing carbon capture on working landscapes. We start with the creation of a Carbon Farm Plan (CFP), where our team works with a farmer or rancher to assess all the opportunities for GHG reduction and carbon sequestration on their property.
The Carbon Cycle Institute (CCI) advances the carbon cycle as the fundamental organizing process underlying land management and on-farm conservation in our efforts to mitigate and adapt to the global climate crisis. CCI advances this work through its Carbon Farming education, training and carbon literacy, which supports producers and their technical service providers to build soil carbon and critical ecosystem services on ranches, farms and other working landscapes.
Carbon Farming Implementation
TThe Carbon Cycle Institute has developed a model framework for land management that emphasizes carbon as the organizing principle. Land management within this framework leads to enhanced rates of carbon capture, increases the provision of important ecosystem services (including water), builds agricultural resilience and mitigates climate change. The framework relies on sound policies, public-private partnerships, quantification methodologies and innovative financing mechanisms that ultimately empower local organizations to efficiently implement on-the-ground, effective solutions.

Carbon Farming Practices
Recent studies have confirmed the efficacy of innumerable agricultural conservation practices in increasing soil carbon sequestration. For example, compost use has been shown to increase the amount of carbon stored in both grassland and cropland soils and has important co-benefits, such as increasing primary productivity and soil water-holding capacity, as well as avoiding the emission of greenhouse gases associated with landfilling or combustion of organic materials. There are at least thirty-five Natural Resource Conservation Service (NRCS) conservation practices that are known to improve soil health and sequester carbon, while producing important co-benefits, including: increased soil water holding capacity, hydrological function, biodiversity, and resilience.
