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. Read more »

Building on our long-term efforts relating to dairy nutrient management, we now have a new publication that summarizes the various approaches being explored for nutrient recovery on dairies – and what we know about the current costs and performance that are associated with each strategy. The publication, Approaches to Nutrient Recovery from Dairy Manure, was a long term effort by Craig Frear (formerly of CSANR), Jingwei Ma, and Georgine Yorgey (CSANR). This publication is a companion to The Rationale for Recovery of Phosphorus and Nitrogen from Dairy Manure.
CSANR has worked in the field of dairy waste nutrient recovery for a number of years. Please visit our Anaerobic Digestion topic page for additional publications, videos, and resources, as well as our Anaerobic Digestion Systems project page for specifics on our work.

2017 was an incredibly busy and productive year for us at CSANR, and I’m pleased to be able to share some of what we accomplished through our 2017 annual report (.pdf). Among the highlights:
- Laura Lewis was named the leader of the new WSU Food Systems Program, and Kirti Rajagopalan joined us as an assistant research professor to co-lead our evolving work on climate and water resources.
- Marcy Ostrom and David Granatstein co-taught a graduate-level Agroecology class.
- We funded 9 BIOAg projects led by WSU colleagues, including projects to: increase legume nodulation for improved symbiotic nitrogen fixation (Mike Kahn); evaluate the impact of border vegetation patterns on blueberries (Lisa DeVetter); and explore sustainable crop-livestock integration in the dryland areas of the inland Pacific Northwest (Haiying Tao).
Stepping back: What have we learned about agriculture and climate change, and where do we go from here?

As a number of large climate-and-agriculture projects at our Pacific Northwest universities have come to an end over the last year, we felt it was time to step back and take stock. Our projects have included dryland wheat farming, anaerobic digestion systems for dairies, and improving understanding of the interactions among carbon, nitrogen, and water at the regional scale. Now that they are complete, what have we learned? Where should research and extension go from here? In an effort to prioritize and catalyze future regional research and extension efforts, we worked with partners to host a workshop titled “Agriculture in a Changing Climate” (March 9-11, 2016). The event brought together a diverse set of stakeholders—university faculty and students, crop and livestock producers, and individuals representing state, tribal and federal government agencies, industry, nonprofit organizations, and conservation districts—to summarize what we know, identify challenges and gaps, and define priorities for moving forward. Since that workshop, a group of us have been working together to continue to synthesize recent research findings and identify priorities related to climate mitigation and adaptation in the Northwest, and the product of that work is now freely available as an online article.

Dryland crops are a common sight east of the Cascades, and cover a LOT of acreage in the Pacific Northwest – more than 5.8 million acres according to recent statistics. Over the last three years, a group of us at CSANR have had the privilege of working with more than 40 co-authors (!) from our region’s three land grant universities – WSU, University of Idaho, and Oregon State University – and from USDA Agricultural Research Service to summarize the most up-to-date scientific knowledge about our region’s dryland systems. That work has now been published as a book, Advances in Dryland Farming in the Inland Pacific Northwest. With touchstone chapters on climate considerations (which has always played a predominant role in determining what crops can be grown) and soil health, this wide-ranging book has chapters on conservation tillage systems, residue management, crop intensification and diversification, soil fertility management, soil amendments, precision agriculture, weeds, diseases, and insects, and policy. We invite you to explore the books many chapters online here or download the entire book as a PDF. If you know you will want to read this book and refer to it over time, you can also receive a free printed version as long as funds allow, by ordering here. Read more »

Successful farmers are skilled at coping with risk, from weather to markets, and a variety of other factors. So to answer the question, “what practices might best help our region’s farmers adapt to climate change?” we went straight to the source. Our region is home to many accomplished farmers who are pioneering a range of new farming practices that improve sustainability, enhance resilience, and are likely to be helpful in adapting to climate change. Their farming practices include reducing and eliminating tillage; diversifying crop rotations; integrating livestock and cover cropping into dryland wheat rotations; and working with partners in their communities to address water related issues.

Over the last three years, we have compiled annual reports in order to better share our accomplishments and reach out to our stakeholders – but I also find that the process powerfully reminds me why it’s such an incredible privilege to work at CSANR, an organization which brings together an incredible range of perspectives and expertise within and outside the university, to make progress towards more sustainable agricultural and food systems in our state.

Organic matter – the organic component of soil – is key to soil health. Organic matter serves as a reservoir of nutrients for crops, provides soil aggregation, increases nutrient exchange, retains moisture, reduces compaction, reduces surface crusting, and increases water infiltration into the soil. And organic matter is closely related to soil organic carbon, the carbon stored in organic matter. Soils with high levels of organic matter have higher levels of carbon, and consequently also benefit the climate by “sequestering” carbon that otherwise would be in the atmosphere.
In the rain-fed croplands of the Pacific Northwest, wheat-based agriculture has historically mined carbon out of the soil. Near Pendleton, winter wheat grown every other year depleted soil organic carbon up to 63% over 80 years of cultivation. Re-building soil carbon is thus an important task for supporting continued agricultural productivity across the region. Read more »

WSU Extension is hosting an upcoming workshop on the basics of High Residue Farming on November 30, 2016, 9:30-3:30 in Moses Lake. Details for those interested in attending are available here (lunch included if you pre-register by 11/22).
High residue farming is a term that covers a number of different specific farming practices, including strip-till and direct seeding. In all these systems, the amount of tillage is reduced in order to maintain crop residues on the soil surface. High residue farming provides a number of benefits, but two key ones include reducing wind erosion (and the need to replant sand-blasted crops) and reducing the amount of time and equipment needed to plant. It can also improve soil health, increase the amount of carbon stored in the soil, and in some cases increase the potential for double-cropping. Read more »

Biosolids? Yes, that means sewage sludge. Well, sort of. But before you say YUCK and click off the page, let’s start with what they really are: biosolids are the materials produced from digestion of sewage at city wastewater treatment plants. They are rich in plant nutrients such as organic carbon, nitrogen, and phosphorus, and can be applied to wheat, alfalfa, and timber land for plant fertilization and soil conditioning. When biosolids are applied at rates that meet plant nutrient needs, farmers and researchers are seeing crop yields equal to or greater than those seen with synthetic fertilizer. Applying biosolids as fertilizer also allows them to be recycled for a useful purpose rather than disposed of in landfills or incinerated.
