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.

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.

It said on the screen, “Bioregenerating Soil-Based Space Agriculture.” The title of the talk was “Beyond Intensification.” The speaker, a prominent researcher and prolific author, someone who I thought would present clear thinking on how, in addition to intensification of current agriculture, we can go about producing enough food for the earth’s growing population. I glanced around to see if anyone else was astonished. Space farming, he said, was the next step after agricultural intensification with food coming from the Moon and Mars. “Has it come to that?” I thought.
I am a fan of science fiction, not a costumed, Trekkie-conference fan, but a fan. However, over the years, I have realized that the stories I enjoy most are mostly fiction; the science is often ignored. This is “soft” science fiction, the stuff of most Sci-Fi movies because there is a way to visit distant planets; think warp drives on the Enterprise, a hyperdrive in the Millennium Falcon, and wormholes in Interstellar.

I will remember winter 2014-2015 as the winter of seemingly never-ending fog, and snow that didn’t stick. That sucks on so many levels, particularly for what it will mean come July and August when we have a serious water problem in the Inland Northwest. I keep getting asked “is this climate change” and “is this what we have to look forward to?” Read more »

Anaerobic digestion (AD) with methane capture and conversion is the most straight-forward, bankable strategy for reducing agricultural greenhouse gas emissions. In fact, it is the only agricultural carbon mitigation strategy that has achieved wide-spread acceptance in a variety of voluntary and mandatory carbon mitigation policies. In a sense, it is the closest thing to a “silver bullet” carbon mitigation solution that exists in agriculture. However, AD still has limited overall market penetration in US livestock production systems, in large part because of the perception that it is really expensive technology. Read more »

Nearly everyone agrees that producing ample, nutritious and safe food to feed 9 billion people, with minimal harm to the environment, is one of mankind’s grand challenges. In the May 14, 2014 issue of National Geographic, Jonathan Foley sets out a thoughtful, five-step plan that highlighted these imperatives:
- “Freeze agriculture’s footprint” (e.g., stop clearing tropical rainforests),
- “Grow more on the farms we’ve got” (close the yield gap, more multi-cropping),
- “Use resources more efficiently” (help farmers “get smarter”),
- “Shift diets” (more fresh fruits and veggies, less grain-fed meat), and
- “Reduce waste” (25% food calories wasted; 50% of food by weight). Read more »

In a previous post, I explained that available evidence currently indicates nitrous oxide emissions may be fairly low in the inland Pacific Northwest, compared to other cropland agricultural systems in the U.S. and world. If ongoing research confirms these early results, then I suggested that efforts to reduce nitrous oxide emissions need to focus on strategies that offered strong co-benefits. Read more »

On a brown, August-dry field in Eastern Washington, a farmer in a combine cuts a 24-foot swath across a field of wheat. The harvested grain then begins a journey, first to the storage bin, then to the local elevator, on rail to a flour mill, by truck to a bakery, by oven to bread, and by car to a home where it is eaten. This is good; our foremost mandate to agriculture is to produce food. However, with this successful export of food from farm fields to nearby and distant cities comes a problem: the nutrients in the bread, the nutrients that we need from food, and that plants need to grow, are now far from the field they came from. How do we replace them?
High yields, which we want, increase the problem. A typical irrigated winter wheat field will yield 140 bushels per acre; about 5,600 loaves of bread. For a center pivot circle of 100 acres, the nutrients in those loaves amount to 182 pounds of N, 70 of P2O5 and 49 of K2O and smaller amounts of other essential nutrients that do not have to be replaced every year. All this ends up somewhere else (in people’s bodies or in sewage treatment plants); it will not be returned to the field1. Read more »

This week, CSANR released its annual BIOAg Program request for proposals for new research and extension projects. The RFP can be found here.
This competitive grant program is the key mechanism that CSANR has to engage a broad, interdisciplinary spectrum of WSU faculty in projects that further the development, understanding, and use of biologically intensive and/or organic principles, practices, and technologies to improve the sustainability of agriculture and food systems in Washington State.
