The production of crop residue varies dramatically across the Inland Pacific Northwest, with estimated residue production for winter wheat ranging from roughly 0.9 ton/acre in the drier grain-fallow cropping system (Figure 1) to 8.5 ton/acre in the wetter annual crop system, which has enough precipitation to support cropping every year. Crop residues are often seen as simply something to “manage” so that they don’t impede future plantings or as a byproduct that can be sold to help improve the bottom line. However, while editing chapters for the recently released publication Advances in Dryland Farming in the Inland Pacific Northwest, I was introduced to another way to think about these residues in the chapter in that publication titled “Crop Residue Management.” The lead author, Haiying Tao from Washington State University, and her co-authors make the interesting point that crop residues should be seen as a valuable resource and that there’s an important tradeoff that should be considered before exporting them from the farm. Residues not only serve a critical role in protecting soils from wind and water erosion between crops, they also add carbon and nutrients back to the soil, improving soil health and helping to maintain its productivity over time.

This year CSANR sponsored registration for several WSU students to attend the Tilth Conference. We have posted reflections written by the students over the past several weeks. Please feel free to comment and give these students your feedback.
I’d like to preface this blog post by thanking WSU CSANR and Tilth Alliance for generously supporting the costs of my trip to Vancouver. Fact is, I wouldn’t have gone otherwise. As a full-time student, it’s all too easy to stay ‘on-rails’—incentivizing constructive risks, like trekking to an interdisciplinary conference—is chicken soup for the student soul. But now I’m mixing metaphors.
My expectations were essentially ‘nil’ preceding the conference: maybe I’d meet a future employer; “gee, never been to Vancouver before”; “with a name like Tilth, it’s got to be good”; conference SWAG. I’d examined the seminar docket ahead of time – looked an awful lot like a WSU syllabus: The View From 400 Feet: Sensors and Analytics in Precision Agriculture, From Farm Worker to Farm Owner: Experiences of Latino Farmers Across Washington, Produce Processing Capacity in Washington State for Farmers and Buyers, etc., etc. Alas, WSU CAHNRS does its job too well!

My name is Khalid Almesfer, and I have a Master’s Degree in Soil Science. Now, I am PhD student in Soil Science at Washington State University (WSU).I watched how desertification and pollution were affecting agricultural land in my country (Saudi Arabia) and I decided to study soil science (soil chemistry) as a major in college. I had always felt that I was inclined to this kind of study. In addition to this, I found that there is a growing need for specialists in this field who could implement and advance scientific skills in soil chemistry, which is very important in my country, which is witnessing an accelerated development in all agricultural sectors. I also participated in different research projects including a survey on soil resources and water quality evaluation in Southern Tihama plains, Saudi Arabia in 2004-2008, and an integrated survey for natural forests in the western and southwestern regions of Saudi Arabia in 2000-2003. I participated in a study on evaluation of soil pollution around Mahad AD’ Dahab Mine and also participated in a baseline of secondary treated sanitary waste-water irrigation at Al-Kafji Joint Operation, and in the evaluation of pollutants in agricultural soils, together with evaluation of soil degradation (features and causes) in some irrigated agricultural soils in Saudi Arabia.
