Compost Climate Connections Webinar Series: Carbon Farming with Compost

Date: 27 Sep 2019 | posted in: Composting | 0 Facebooktwitterredditmail

Our Compost Climate Connections webinar series features the crucial role of compost to protect the climate. Calla Rose Ostrander joined us in the second webinar of the series to discuss the Marin Carbon Project and the Project partner’s work on carbon farming and its potential to mitigate climate change. Carbon farming involves implementing practices that are known to improve the rate at which CO2 is removed from the atmosphere and converted to plant material and soil organic matter. For more than a decade, the Marin Carbon Project has demonstrated that managing for carbon can actually increase the system capacity to hold even more carbon. Its first experiments involved applying a thin layer of compost to grazed rangeland. One finding: per hectare, a single application of compost, on average, sequesters one ton of carbon per year on an ongoing basis. View the recording below!
