John Williams, Stewart Wuest and Kate Reardon hosted a booth at the annual Explore Career Fair November 4th. The career fair was attended by approximately 1000 youth and community members.
- Soil Scientist Ron Rickman (retired) and biological research technician Tami Johlke have been invited to present “Wheat Development and Growth” at WSU’s Wheat Academy held in Pullman WA December 16-17, 2014.
Hero Gollany monitors greenhouse gas (GHG) emissions in the long-term no-till wheat-fallow, wheat-pea (LTE NT), and conventional tillage experiments (LTE CT) to estimate emissions of carbon dioxide and nitrous oxide and determine the global warming potential of each cropping system. Wayne Polumsky (right) injects soil atmosphere gas into a collection vial. Joe St. Claire (left) collects soil atmosphere gases from a gas chamber in the long-term no-till plots for GHG determination.
- John Sulik and Dan Long are preparing a manuscript entitled “A Spectral Index for Reproductive Growth of Vegetation” for publication in a major remote sensing journal. This article describes work on a new spectral index that may be useful for monitoring crop growth and estimating within-field yield potential during flowering of various field crops.
Stewart Wuest and Tami Johlke continue to monitor the gain and loss of water from lysimeters, but this may be the last time this winter. The lysimeters allow us to compare different soil surface conditions, such as the amount of tillage and residue cover. It appears that evaporation after a rain and evaporation during a dry summer are very different processes.
- Aron Boettcher, Dan Long, and OSU weed scientist Judit Barroso are establishing experimental protocols for measuring the effect of weeds on grain yields in the cereal-oilseed rotation study. Judit and Dan are writing a proposal that will seek funding for identifying the impact of oilseed rotations on weed communities.
Joe St. Claire uses a bar code scanner to obtain a soil weight measurement from a platform balance. The measurement is transmitted via a wireless connection to a centralized data storage and retrieval system that is accessed over the Internet. This “Cloud Computing” approach allows for simultaneous data sharing with multiple users rather than waiting for the data to be saved and emailed.
- Stewart Wuest presented research findings on building soil organic matter and how to improve soil performance at the December 2014 conference, Building Soils for Better Crops, Moses Lake, WA.
Wayne Polumsky obtains a small sample of gas from agricultural soils using a static chamber and syringe. Samples are being taken each week to determine changes in emissions of gas over time. The method is used to estimate contributions of agricultural practices to the greenhouse effect.
- Janaina de Moura Oliveira returned home to Goias, Brazil after an eight month stay in Pendleton. During this time, she trained and worked with Hero Gollany on developing a data-base for the crop-livestock integration system and simulating several management scenarios using a soil carbon model to predict the best management for carbon storage in Brazilian soils.
Kate Reardon and Hayley Peter-Contesse are analyzing soil samples from the biofuel systems trial for microbial ammonia oxidation activity.
- Aron Boettcher is completing a water balance analysis summarizing the consumptive water use of different crops in the 2014 cereal-oilseed rotation study west of Pendleton. Aron and John McCallum are creating posters that will present the results of field oilseed research at the Direct Seed and Oilseed Conference in Richland, WA on 22 January 2015.

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.
