Every year the second week in September (7th-13th this year) is designated as Washington Organic Week (WOW!) to celebrate the organic farmers, farms and food and the bounty of the harvest in our state (learn more HERE). Nationally, the organic sector did well in 2013, reaching $32.3 billion in retail food sales, up 11.4% from the previous year (Organic Trade Association, 2014). The steady growth in demand can be seen in Figure 1 below.

Dairy Waste Biorefineries: An Innovative Way to Further Reduce Greenhouse Gases on Dairies in Washington State
Posted by Nicholas Kennedy | September 3, 2014
Washington State, 10th in milk production nationally, is also at the top of the list for greenhouse gas (GHG) emissions produced from dairy cattle. According to the latest statistics by the EPA, in 2012 Washington State ranked 8th in methane (CH4) emissions from dairy manure management and 12th in nitrous oxide (N2O) emissions (EPA, 2014). Understanding the effect the dairy industry has on climate change has led the state to leverage its many public research institutions and agencies including the Washington State Department of Agriculture (WSDA), Washington State Department of Ecology, and Washington State University’s Center for Sustaining Agriculture and Natural Resources (WSU CSANR) to help dairy farmers better manage and mitigate GHG emissions on large scale dairies also known as concentrated animals feeding operations (CAFOs).

A new paper published in Environmental Science & Technology (DeLucia et al., 2014) suggests that scientists have drastically underestimated the earth’s theoretical potential to produce biomass – by as much as 2 orders of magnitude! That’s going to take a minute to wrap my mind around.

“The Nation’s Leading Potato Producing County” states a sign on I-90 at the Grant County border1. In 2010, Washington potato yields averaged 33 tons per acre, compared to Nebraska at 20.7, Wisconsin at 19.8, and Maine at 14.5 tons per acre (Idaho’s main potato producing counties averages 27.2 tons per acre). And it is not just potatoes; the Columbia Basin produces high yields of corn, dry beans, onions, and many other crops. However, the productive soils in the Columbia Basin often have soil organic matter levels less than 1%, much less than the level considered as adequate for proper functioning, and certainly not high enough to be considered high quality soils. How can such “low quality” soils produce high crop yields, yields higher than other regions with higher soil quality? This paradox highlights a problem with the concept of soil quality; that it does not take into account the soil management practices that farmers employ to overcome problems in so-called “low quality soils” and therefore does not reflect real production capacity of soils, especially in the West.

Nobel Peace Prize recipient and Director of the Purdue University Climate Change Research Center, Dr. Otto Doering, recently gave a keynote speech where he highlighted his definition of Wicked Problems facing the globe and the US.
In brief, he used US struggles regarding affordable health care and the debate regarding the Affordable Health Care Act as a prime example of a Wicked Problem. Regardless where one might stand politically on such an issue, it is clear that the issues of affordable health care and potential policy solutions are of great importance to many, with its tentacles reaching into vast and diverse sectors of our society. No clear consensus on how to solve the problem appears to be present, due to the complexities and interrelationships involved. In particular, solutions can be shown to result in a cascade of unknown consequences, either positive or negative, with individual stakeholders holding a diversity of economic, personal and social viewpoints.

New Meta-Analysis Identifies Three Significant Benefits Associated With Organically Grown Plant-Based Foods
Posted by Chuck Benbrook | July 11, 2014
There have been four progressively rigorous meta-analyses published since 2009 focusing on differences in the nutritional quality and safety of organic versus conventional food. The latest comes out July 15, 2014 in the British Journal of Nutrition (BJN). I was the sole American scientist on the mostly European research team that produced the BJN paper:
Higher antioxidant and lower cadmium concentrations and lower incidence of pesticide residues in organically grown crops: a systematic literature review and meta-analyses. Baranski, M., D. Srednicka-Tober, N. Volakakis, C. Seal, R. Sanderson, G. B. Stewart, C. Benbrook, B. Biavati, E. Markellou, C. Giotis, J. Gromadzka-Ostrowska, E. Rembiałkowska, K. Skwarło-Son, R. Tahvonen, D. Janovska, U. Niggli, P. Nicot and C. Leifert.

There are a number of sustainability issues getting a fair amount of attention these days: climate change, regional and local food systems, and soil health, to name a few. While this is obviously good, there are also issues that may be getting somewhat less attention than they deserve. And closing the nutrient loop is one of these. Read more »

Problems triggered by the spread of glyphosate-resistant weeds in corn, soybean, and cotton country continue to worsen. An industry source recently projected that 70 million acres are now infested with one or more glyphosate-resistant weed. The presence of glyphosate-resistant weeds forces farmers to add additional herbicides to their control programs, and apply herbicides more often and/or at higher rates. Costs have risen $25 to over $75 per acre. Read more »

Remember last winter? As June warms and temperatures in the 90s are in the forecast, it may be hard to recall, but here in the Columbia Basin, it was dry with a few notable cold spells. That combination of cold and dry can be hard on plants, agricultural and ornamental.
Plants, both annuals and perennials, from wheat to lavender, alfalfa to ziziphus, vary in their ability to survive winter conditions. However, there are three factors that combined to make last winter a “hard winter.” Read more »

If you are interested in ensuring that farming is climate friendly you are likely to start thinking about nitrous oxide (N2O). Nitrous oxide is a powerful greenhouse gas (298 times as powerful as carbon dioxide, over a 100-year time frame). And nitrous oxide from agricultural soils is the single biggest contributor to agriculture’s direct greenhouse gas emissions, as estimated through inventories of greenhouse gas emissions. In Washington State, it was estimated that nitrous oxide from soils accounted for 46% of direct greenhouse gas emissions from agriculture in 2008.1 However, these estimates rely on “default” assumptions about nitrous oxide emissions that were developed from global data – and a review of existing experimental data in our region suggests these defaults may not be appropriate in our region.
