Check back here often for more local event updates from USDA-ARS Pendleton, Oregon.
The First Wednesday discussion in August has been cancelled, as harvest is keeping everyone very busy. We will see you in September!
The next First Wednesday Seminar will be September 7th, 12:05 pm. Come join us!
Presenter: Jay Gibbs, NRCS Team Leader for John Day/Umatilla and Snake River Basins
Title: A Discussion on CRP
The Conservation Reserve Program has had a major influence on farming and communities in many areas. Many contracts are not being renewed. This raises serious questions about the best ways for putting these acres back into production. There are also questions on the potential pressure on land values, alternative uses, and how it will affect progress on soil erosion and habitat.

Staff at the agricultural research station get together on a monthly basis to talk research findings, issues, ideas, and aspirations. We meet the first Wednesday of every month, from 12:05 to maybe 1pm, in the conference room, 48037 Tubbs Ranch Rd, Adams OR. It is informal, everyone is welcome, and you can leave whenever you need to.
If you would like to receive e-mail correspondence about the First Wednesday Discussions, please e-mail Brenda Carlson (Brenda.Carlson@ars.usda.gov).
Stewart and Bekah pulled large cores from a low-rainfall research site and placed them in a lysimeter study at the research station. Some of the cores were placed directly into plastic buckets, which will be placed in liners in the ground and weighed weekly to follow evaporation and capture of rainfall. One of the lysimeters was repacked with water potential sensors placed at several depths (photo) to monitor the movement of water. The lysimeter setup allows us to follow gain and loss of soil water in different soil types and under different surface residue amounts and tillage treatments. July 13, 2016.

Hero Gollany is monitoring soil carbon and nitrogen changes in six cropping systems in the GRACEnet, long-term no-till and conventional tillage experiments. Wayne Polumsky is taking the photo while Steve Umbarger is sweep tilling the fallow phase of winter wheat-fallow rotation in the GRACEnet plots. July 11, 2016.
Each year, the ARS owned Case IH combine is taken off-station to harvest a few farmer-owned fields. The combine is equipped with GPS receivers, a yield monitor, and two optical sensors for measuring grain protein. Observers ride outside the combine to monitor the instruments. On July 6, yield and protein were mapped within a 40-ac winter wheat field near Pendleton. One of the optical sensors is sensitive to chlorophyll particles from green weedy material in the grain stream. This information is being applied into mapping infestations of Russian thistle, kochia, and other weeds that mature well after wheat is harvested.
ARS scientists mounted an optical sensor on a combine to measure and map the seed oil concentration of canola as it was harvested over June 29-30. Shown is the Polytec model 1721 sensor on the grain bin filling auger in the grain tank of the combine. The measurements help with understanding how seed oil concentration varies across farm fields.

The scientists are also interested in knowing how much oilseed variation is lost when the harvested canola seed reaches the elevator. Here, a Polytec sensor is also mounted to the conveyor at the elevator. A measurement of seed oil concentration can be made each second. Batches of seed differing in oil concentration could be blended to a constant oil content and if that is possible, then a cold pressing operation could be optimized to lessen the loss of oil in the meal.
