Upcoming

  • Dan Long was invited to present his research on on-combine optical sensing at a breakout session of the Direct Seed and Oilseed Conference in Kennewick, WA on January 20, 2015.


  • John Sulik was invited to participate as a member on a panel discussing applications of unmanned aerial systems at the Direct Seed and Oilseed Conference in Kennewick, WA on January 20, 2015.


  • Dan Long will serve on the evaluation panel for the Forage Seed and Cereal Research Unit’s Research Leader position in January.

Current


    The arctic air mass that arrived this weekend brought sub-zero temperatures, snow, and ice. Temperatures Wednesday, November 19 will remain in the lower teens for much of the day.


  • Stewart Wuest and John Williams are analyzing data from a seven year experiment. Soil water under chemical fallow, tilled fallow, and annual winter wheat were monitored continuously to find out if one system had better water storage through increased rainfall capture or reduced evaporation. The experiment was located in a 16 inch rainfall zone.


  • Dan Long is revising a scientific manuscript that will report on the economic feasibility of variable-rate nitrogen management on spring wheat in summer fallow systems.



  • Kate Reardon and John Williams are conducting an experiment to test whether oilseed crops influence the soil hydrology and/or microbiology in winter wheat crop rotations. The canola was seeded on the 22nd of September and has responded well to the recent moisture. With slightly more than average growing degree day heat units, the crop appears well on the way to developing past the five leaf stage needed for overwintering.



  • Aron Boettcher is completing the summaries of data for the oilseed stress and mixed cereal-oilseed cropping systems trials that were conducted in 2014.


  • Hayley Peter-Contesse was recently hired by Dan Long to conduct a life cycle assessment of carinata-derived jet fuel and diesel when this crop is grown in rotation with wheat and summer fallow.


  • Hero Gollany attended the annual meeting of the Soil Science Society of America in Long Beach, CA during Nov. 2-5, 2014. She presented the paper “Measured and CQESTR Simulated Soil Organic Carbon Changes of Dryland Agroecosystem Under Climate Change Scenarios”, presided over a live-streaming session “Agricultural Practices to Improve Nitrogen-Use Efficiency and Mitigate Greenhouse Gas Emission: I”, and co-organized the workshop “Measurement Issues for Nitrous Oxide Emissions from Soil” on November 6, 2014, following the regular meeting.


  • Hero Gollany’s research team seeded winter wheat, Austrain pea, and tritcale in the GRACEnet plots, long-term no-till and conventional till experiments.



  • Steve Umbarger is seeding winter wheat with ConserveaPack in the GRACEnet plots.



    Steve Umbarger is seeding Austrian pea while Wayne Polumsky is redistributing the wheat residue in the long-term no-till (NTB) experiment.


  • John McCallum is evaluating the performance of an inexpensive, off-the-shelf spectrometer and determining if it can be adapted for use on a combine harvester to measure the protein or oil content of grain during harvesting.


  • John McCallum recently met with Mark Manahan of Cosa Xentaur. The two of them updated the temperature control and spectrometer of the Nuclear Magnetic Resonsance instrument that is being used to measure the oil concentration of seed samples from harvested plots.



  • A former employee of ARS is shown (left) with pumpkins she has gathered for local foster children from the on-site OSU pumpkin patch. Tami Johlke, biological science technician, is shown (right) with her great-nephews and the pumpkins they gathered.

    ARS technician Elizabeth Torres and Washington State University technician Jeanene DeAvila preparing samples for DNA analysis. Kate Reardon hosted Jeanene DeAvila as part of a collaboration with Professor Tarah Sullivan to investigate the effects of soil treatments on fungal and bacterial populations in grape and wheat cropping.


    Hero Gollany and her team performed soil sampling in the long-term conventional tillage, no-till winter wheat–pea cover crop rotation and winter wheat– fallow plots. From left to right, Wayne Polumsky, Patrick Nash, and Joe St. Claire are shown preparing for the next sample extraction.


    Stewart Wuest, Tami Johlke, and Steve Umbarger seeded on-farm test plots in a grower’s field. The test plots received one non-inversion tillage pass the 29th of May, leaving all of last year’s crop residue on the surface. We were successful in placing the seed into moist soil, and we have hopes that it will emerge sooner than the rest of the field where the seed was “dusted in” and is waiting for rain. This region has received very little effective rain so far this fall.
