Flex Cropping – Storing More Carbon Under Challenging Environmental Conditions

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.[1] Re-building soil carbon is thus an important task for supporting continued agricultural productivity across the region.

Farm Incubator Programs Offer Strong Foundation

Posted by Janel Davisson | December 14, 2016

This year CSANR sponsored registration for several WSU students to attend the Tilth 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.

orchard-picMy name is Janel Davisson, I am a senior at WSU in the Organic Agriculture program. I attended the Tilth Conference last year in Spokane and I was excited to get the opportunity to go again. Last year I really enjoyed the varied topics of discussion and the practical knowledge that was shared, and was looking forward to hearing from people working in their field of passion.

This year in Wenatchee one of the workshops I attended was on farm incubators by Kate Smith, a graduate student at WSU. The current studies on incubator farms are miniscule at best, partly due to the infancy of this program. The goal of these farms is to introduce new farmers into the system and get them a solid foundation to begin their farming careers. Going into this workshop I had an elementary knowledge of what an incubator farm entailed. I knew that larger farms would lease out small plots of land to up and coming farmers and provide infrastructure and knowledge shared by landlords and other incubator farmers. What I didn’t realize was the extent to which these farms provide for the new farmers. Viva Farms in Mount Vernon not only provides the land, but they also work with the local school to provide an in-class education and on-farm practicum on how to run a farm. One of the biggest surprises to me was that they also subsidize capital loans to the farmers to help them get started. Read more »

In a past post, I argued for the use of an herbicide instead of tillage to kill a soil-building cover crop. My post was mostly observation of the damage of tillage on the soil as compared to the lack of damage, at least visually, from the herbicide. But others suggested that herbicides may not be as benign in the soil as I portrayed them. Here is the latest science on the topic.

A series of reviews have been published on the effects of herbicides on the soil, starting with Bunemann et al. in 2006. They concluded, “The herbicides generally had no major effects on soil organisms.” More recently, a review by Rose et al. (2016) found, “Overall, the majority of papers reported negligible impacts of herbicides on soil microbial communities and beneficial soil functions when applied at recommended field-application rates.” Read more »

Resiliency achieved by sustainable agriculture

Posted by Corina Serban | December 5, 2016

This year CSANR sponsored registration for several WSU students to attend the Tilth 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.

corinaMy name is Corina Serban, and I am currently working towards my Master of Science in the Horticulture department at Washington State University. Attending the Tilth Conference for the first time gave me an ideal opportunity to network with other professionals and learn a lot from the workshops presented.

This year’s conference focused on change and resiliency. It brought ideas and people that inspire organic and sustainable farming. I personally found this event to be valuable to me as a Horticulture graduate student. Through my research, I want to contribute to the development of pre- and postharvest management strategies to reduce physiological disorders related to calcium deficiencies on ‘Honeycrisp’ apples. Even though my research approach is on conventional orchards, I have always had a passion to know more about organic and sustainable tree fruit production. Since I was a kid, I enjoyed being in the natural world and had my own garden. I grew up with values that show how important is the respect for the land and the care that is an integral part of growing healthy and nutritious crops. After sharing my ideas with others who were passionate as well about organic and sustainable agriculture, I felt like I was in the right place.  I could express my opinions and learn about new ideas and technologies in sustainable agriculture.

Crop rotation: In praise of deliberate, sequenced disruption of natural systems

Posted by Andrew McGuire | December 1, 2016

For years, researchers have been looking to polycultures, biodiversity in space, as a way to improve agriculture (Trenbath 1974; Tilman et al. 1997; Cardinale et al. 2011; Finney and Kaye 2016). Behind this research is the idea that nature is the best model for agriculture. Because we find that nature is generally a polyculture, we should mimic this biodiversity on the farm. Natural is now viewed as the best option. Today, however, I want to commend a most unnatural practice, crop rotation.

A Good Harvest: Mendoza and Baird dazzle the Quincy Success Summit

Posted by Marcy Ostrom | November 22, 2016

oscar-romero-2016-iris-summit-logoAs shown in this logo designed by Quincy resident Oscar Romero, the theme of last Tuesday’s bilingual community summit held at the Quincy Junior High as “Seeding Success, Growing ONE Community.” A team of bilingual junior high students and faculty, along with local volunteers hosted over 160 community members in a discussion about how to protect our region’s land and water resources and build community health and prosperity.  “Fostering cross-generational relationships, a sense of belonging, and knowledge and resource sharing” were among the subjects highlighted in a collection of over 60 short stories submitted by local citizens. These essays, chronicling recent “successes” both large and small were used to inspire deliberation, celebration, and action in small work groups. 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 »

The New Urban Indoor Industrial Agriculture… but Why?

There is a new style of urban agriculture appearing around the world. The efforts differ in details, but they all use buildings or structures not originally designed to grow plants – no greenhouses. Carried out in old shipping containers, warehouses, and high-rises, perhaps even in an old factory or two, these “farms” bring agriculture fully indoors. Without sunshine, these farms rely on artificial lights shining on plants 24 hours a day in some cases. Without soil, plants sit in plastic pipes, or float on polystyrene rafts, stacked in tiers.  Without rain, nutrient enhanced water is cycled to the plant roots through piping, pumps and filters. Without wind, fans provide ventilation, ducts and vents deliver heated or cooled air for year-round production.

All this requires energy. These farms are plugged in, reliant on outside power. Outdoor farm fields are off the grid, at least for the production portion of the food chain. Even a continuous corn crop, the scorned example of “industrial” agriculture, is not affected by a blackout. While an outdoor “industrial” crop is still subject to the biological realities of crop growth cycles and seasons, crop production in these indoor farms can be sped up and streamlined. All it takes is lots pipes and tanks, cables and lights. Read more »

Weather is the most important driver of agricultural production. Year-to-year changes in the weather affect growing conditions, which then lead to important swings in yields, quality, timing and marketability of Pacific Northwest products such as apples, wheat, potatoes, and hay. In a similar way, changes in climate are leading to changes in growing conditions, and these changes also pose risks to production. Growing condition analogues are an approach to identifying and exploring past experiences that are relevant to understanding the risks expected in the future.

Over the years—and in some cases over generations—producers have refined their management practices to best address the complex interactions between the crops they grow and the wide range of growing conditions that determine the productivity and sustainability of their operation. These best practices are adapted to the local conditions and are continuously improved over the years, creating a rich body of location-specific agronomic knowledge. With the wide range of conditions that have occurred over the Pacific Northwest’s agricultural history—to say nothing of the range of conditions across different agricultural regions in North America—there’s a wealth of experiences out there that growers can tap into. The challenge is to know which experiences can help one determine how best to prepare for what the future will bring for one’s location. That’s where growing condition analogues come in. Read more »
