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 the Center for Sustaining Agriculture and Natural Resources’ advisory committee, Dale Gies.

Biochar as a soil amendment has been the subject of much attention in recent years because of its ability to sequester carbon and to improve aggregation, water holding capacity, and organic matter content of soil amended with it (Lehmann, 2007; Marris, 2006). A recent post discussed what’s needed to economically produce forest to farm biochar. In contrast, researchers at Washington State University are investigating what we could call waste to farm biochar. Waste to farm biochar, if deployed on a larger scale, could offer a two-part benefit – removal of wood from the municipal solid waste stream and creation of a valuable product from this wood. In recent work, researchers are looking at two possible wastes that could be made into biochar: wood-based fractions of municipal solid waste and the large woody material remaining after compost production—referred to as “compost overs.”

Farmers across the globe are grappling with the challenges of a changing climate. In the Pacific Northwest, loss of snow pack has diminished the availability of water resources, causing increased drought stress (see this article, for example). Our program is focused on biochar, a rather non-descript product that can help farmers both sequester carbon and prolong the availability of soil moisture in their agricultural soils to address drought stress.

In November I participated in a truly innovative summit titled, “Safeguarding Idaho’s Economy in a Changing Climate – Our Water, Our Land, Our Health, Our Future” which brought together a diverse coalition of public and private stakeholders to discuss economic resiliency challenged by our changing climate. This first-of-its kind, for Idaho, summit occurred simultaneously in Boise, Moscow, Ashton and Pocatello, ID with keynote speakers in Boise streamed to the remote locations. Keynote presentations were followed by facilitated workshops at each viewing site. The goals of this conference were to share what efforts were underway across multiple sectors of Idaho’s economy to address climate change, explore economic opportunities and efficiencies, build new collaborations and provide resources for future projects at all scales.

The production of crop residue varies dramatically across the Inland Pacific Northwest, with estimated residue production for winter wheat ranging from roughly 0.9 ton/acre in the drier grain-fallow cropping system (Figure 1) to 8.5 ton/acre in the wetter annual crop system, which has enough precipitation to support cropping every year. Crop residues are often seen as simply something to “manage” so that they don’t impede future plantings or as a byproduct that can be sold to help improve the bottom line. However, while editing chapters for the recently released publication Advances in Dryland Farming in the Inland Pacific Northwest, I was introduced to another way to think about these residues in the chapter in that publication titled “Crop Residue Management.” Continue reading →

Extension has traditionally involved getting results from researchers to decision-makers in agriculture. Partly because I work on climate change and agriculture, and partly because of the approach my team and the researchers we work with take, extension is, for us, a two-way street. In this article I want to highlight the “other” side of that street: how innovations that producers test out in real life complement research and supports future preparedness.

In preparation for a new project I reviewed case studies and profiles others I work with published as part of the Regional Approaches to Climate Change – Pacific Northwest Agriculture (REACCH-PNA) project, which focused on dryland cereal production in a changing climate. These case studies tell the stories of producers who are implementing practices that break some mold, and that is leading to both interesting results and to benefits that will help them be prepared for future climates.
