It is time to know your CROPTIME!

Posted by Adekunle Adesanya | January 19, 2016

This year CSANR sponsored registration for several WSU students to attend Tilth Producers of WA annual conference.  We will be posting reflections written by the students over the next several weeks. Please feel free to comment and give these students your feedback.

In humans, after decades of research and innovation, it is still very tricky for medical practitioners to accurately predict a child’s delivery date. Though the doctors estimate delivery dates for expectant mothers, these dates are rarely exactly correct, despite the level of technology involved.

Predicting crop harvest time is not all that different from estimating due dates. Have you ever wondered how complex and challenging it could be to predict the precise harvest date of crops, especially for small scale farmers with limited resources to invest in specialized technologies to support on-farm decision making system? As with doctors and delivery due dates, farmers have an estimate of the time required for the plants to achieve some phenotypic attributes like flowering, fruit setting and ripening etc., but getting it exactly right is rare. This prediction is usually based on prior knowledge about the crop’s biology. However, plant growth and development is largely dependent upon elements of the immediate environment (temperature, light duration, humidity etc.). Thus, crop output in terms of quantity, quality, and timing is dependent on the micro-environment. Therefore for a typical small scale organic farmer, a big question is how to accurately and precisely predict the time period in which harvest is optimal. This is critical to meeting the volatile demand of customers in a timely way (CSA, food co-ops etc.). Read more »

This year was my first time attending Tilth Producers Conference and what an experience it was! I feel almost silly to have never attended in years past; the thought of the people, workshops, and opportunities that I’ve missed is almost distressing. The 2015 Tilth Producers Conference wasn’t just the first conference of its kind that I’ve attended, it was the first conference I’ve ever gone to and so in terms of expectations I really didn’t have any. Having never gone to any conference prior to Tilth was, perhaps, a good thing: I entered the conference as a blank canvas, absorbed everything I could, and left dotted by a rich, colorful array of knowledge and information.

The State of Organic Seed and How it Changed Me

When I entered the “State of Organic Seed” workshop Sunday afternoon of the 2015 Tilth conference I was a total skeptic. My previous learning had focused on the advantages of conventional farming and I had little education in the ways of organic or sustainable farming practices.

That is why when I had the opportunity to attend this conference in Spokane November 15th through the 17th I was both extremely excited but also very nervous. Not only was this my first conference, but it was also a conference with which my views didn’t totally align. As an Agricultural Biotechnology major here at Washington State University I’ve learned a lot about advances in agricultural sciences that have allowed for the use of genetic engineering in plants, otherwise known as GMOs. Up until the conference, I had come to appreciate this technology and believed it was the future of agriculture. Read more »

Schultz Legacy: Moving meat from farm to table

This summer saw the retirement of long-time WSU San Juan County Extension director, Dr. Tom Schultz. Among many notable accomplishments, Tom was a national leader in applying the resources of extension to solving some of the most intractable problems facing local food systems. A plant pathologist by training, along the way Tom also became an expert in participatory community development. Through a process that took years to bear fruit, Tom and determined San Juan Islands citizens worked as part of the Lopez Community Land Trust to identify and break down barriers to local food production and consumption. A concern dating back to the 1990s was the lack of local USDA-inspected meat processing.  Island producers knew they had unique products that their neighbors and others looking for meat raised in a humane, healthy, and clean environment wanted to buy, yet the barriers seemed immense.

The Essentials of Sustaining Agricultural Production

Posted by Andrew McGuire | July 16, 2015

As a member of the Washington State University Center for Sustaining Agriculture and Natural Resources, I work as an irrigated cropping systems agronomist working on ways to sustain agriculture (a professor I know promotes the use of tee shirts that say “I’m an AGRONOMIST – look it up!”). In doing this, I have come to realize that there are certain requirements that agriculture must meet to produce food and to keep producing food (yes, fiber too, and other non-food products, but mainly we are concerned with food production). I view these as a hierarchy, such that if the top requirement is not attained, the lower requirements do not mean much, but once the top requirement has been met, we can move to the next one, provided that how we do it does not threaten any of the requirements above it. Each component is required, but not sufficient; all of them are needed. Read more »

Monoculture vs. Polyculture Part II: “Straight up” beats “cocktails” for cover crop ecosystem services

Posted by Andrew McGuire | June 11, 2015

Cover crop mixtures, known as “cocktails” by some, are being promoted as having benefits over cover crops planted as monocultures. As I described in Part I, I reviewed recent research results to get at the answer to the question, “are monocultures or polycultures better when it comes to cover crops?” I found that, for biomass production at least, monocultures were actually best (see Part I). Now, let’s look at other services provided by cover crops and compare polycultures and monocultures. (See an explanation of monocultures, polycultures, overyielding and transgressive overyielding here)

Monoculture vs. Polyculture Part I: “Straight up” beats “cocktails” for cover crop productivity

Posted by Andrew McGuire | June 8, 2015

Planting cover crop mixtures is very popular right now. The practice has a feel-good aspect about it and, buoyed by the ecological theory, it fits with the current “mimic nature” strategy of agroecologists. In a previous blog post I demonstrated how difficult it is to do research on cover crop mixtures. Although difficult, there are intrepid researchers investigating this practice so I decided to see what they were finding. The results call into question the value of cover crop mixtures, as in many situations a monoculture cover crop would both produce more biomass and provide other desired services as well.

Ecological Theories, Meta-Analysis, and the Benefits of Monocultures

Posted by Andrew McGuire | May 26, 2015

How do we go about increasing agricultural crop yields? As long as human populations are increasing, this is the primary challenge we face in agriculture. We must do this without threatening our ability to produce food in the future, and, if possible, without expansion of agricultural land (see graph below).

Each year CSANR administers an internal competitive grant program called BIOAg to fund new research and education projects focused on improving the sustainability of agriculture in Washington State. To date, through BIOAg and precursor internal grant programs, CSANR has funded 150 projects – many of which have led to significant new investments of extramural funding to further advance these ideas. Over the course of the program [and within each year] we have funded projects ranging from basic science to applied research to extension and educational products and we’ve always been able to maintain a good blend across this continuum.  Read more »

What is Holistic Agriculture?

Recently, I watched a TV program about rehabilitation of sloths illegally taken from the wild for the pet trade in Colombia. According to the narrator, the sloths were treated with holistic medicine. This puzzled me. I thought holistic medicine involved treatment of body, mind, spirit, and emotions. I couldn’t help wondering what we know about the mental, spiritual, and emotional life of sloths.
