We’ve now established scientifically that there is a version of agriculture that actually results in more carbon in the soil in a durable form than is re-released from the enjoyment of the carbohydrates produced.

A little Background
John Wick is a “carbon farmer” focused on finding ways to increase carbon in the soils below his pastures. His goal: produce food, fuel, and fiber, and improve wildlife habitat while also providing a solution to climate change. “And having a lot of fun!” he always adds.
For an overview of what John learned about compost as a climate beneficial farming practice, and examples of how you can get started, check out the these two articles. Read on for links to the Science Papers and to tools and agencies.

What are the benefits of applying compost to pastures and rangelands?
A single application of compost doubled forage production and increased soil carbon sequestration by an average of 1 ton/hectare.
What does this mean for the potential of rangelands to mitigate climate change?
This 2014 paper showed that a single application of compost to grassland soils can increase soil C and N storage in labile and physically protected pools over relatively short time periods and contribute to climate change mitigatiom.
This 2018 paper demonstrates that this practice can actually cool the planet. “Soil organic carbon sequestration through agricultural management has been proposed as a means to lower atmospheric CO2 concentration, but the magnitude needed to meaningfully lower temperature is unknown. We show that sequestration of 0.68 Pg C year−1 for 85 years could lower global temperature by 0.1°C in 2100 when combined with a low emission trajectory [Representative Concentration Pathway (RCP) 2.6]. This value is potentially achievable using existing agricultural management approaches, without decreasing land area for food production.
How long will the benefits of compost application last?
Data from Nicasio Native Grass Ranch showed that 2,000 additional pounds of carbon per hectare was stored every year following the first application of compost. This paper modeled the potential impact, showing that this pattern could continue for 30 to 100 years.
Does spreading compost sequester more carbon than it emits through its production and transportation?
Yes! This study demonstrated that producing compost and applying it to rangelands has the potential to significantly offset GHG emissions. The largest offsets came from diverting manure, and yard and food wastes from landfills which reduced methane emissions.
How does compost compare to spreading manure?
“Manure applications increased forage production and soil Carbon storage, but plant community changes and greenhouse gas emissions decreased, and eventually eliminated, the net climate benefit of this practice.”
Is compost harmful to plant communities?
A one-time compost amendment produced large and persistent increases in aboveground biomass for both grassland ecosystems. It did not majorly affect species richness or abundance. Overall plant communities were resistant to compost addition. This is in contrast to applications of inorganic, nitrogen-based fertilizer which has been shown to increase invasive plants and reduce diversity.
