In non-irrigated areas that are too dry to support annual cropping, fallow (the practice of leaving land unplanted) preserves soil moisture for future crops. However, annual fallow combined with conventional tillage has resulted in a net decrease in soil carbon over time in our region, with negative impacts to soil health across large areas. And even when tillage is eliminated, it is very difficult to maintain soil carbon over time in a wheat-fallow system. For this reason, the impact of climate change on the frequency of fallow in crop rotations has important future implications both for soil health and for opportunities for carbon sequestration.

Anne Schwartz is a long-time CSANR Advisory Committee member, former Tilth Producers of Washington president, proprietor of Blue Heron Farm, and lifelong advocate for sustainable agriculture. Anne is a guest blogger, challenging College of Agricultural, Human, and Natural Resources Sciences faculty, and CSANR faculty in particular, to focus on and address the challenges of True Cost Accounting.
True Cost Accounting is the study in economics that addresses all of the upstream and downstream costs and benefits associated with a set of management decisions and ensuing practices, and their long-term impacts on natural resources and communities. Other terms used to indicate a similar approach include: Full Cost Accounting (FCA), Life Cycle Analysis (LCA), Triple Bottom Line (TBL), Natural Capital Accounting (NCA), and Cradle to Cradle (C2C).

What are the climate impacts of a given farm practice? While we know lots of strategies for reducing greenhouse gas emissions on farms, quantifying that impact can be difficult. However, there is at least one farm in our region –one that uses some pretty neat practices – for which scientists have attempted to answer that question. And the farmer just happens to be a long-time member of CSANR’s advisory committee, Dale Gies.
