Bundle harvest was conducted in long-term no-till and GRACEnet plots on July 29, 2014, and combined harvest was carried out on July 31, 2014. Above is a photo from the bundle harvest in the long-term no-till plots. From left to right are Joe St. Claire, Wayne Polumsky and Aron Boettcher, shown collecting wheat bundles to determine wheat yield, and aboveground biomass production.
Harvest of numerous small plots in all field experiments is now complete. Steve Umbarger uses the Case IH 1470 combine to harvest winter wheat from larger non-experimental areas.
- Dan Long and John McCallum will be leaving for their trip to Malta, Montana to test a new optical sensor on a combine during harvest and obtain grab samples of canola. A mounting plate has been constructed for installing the sensor to the auger housing of a Case New Holland combine. A software interface was written for recording the sensor’s spectra on-the-go and mapping the estimates of seed oil concentration.
Biological Science Technician Aron Boettcher collects post-harvest soil samples from plots that grew different oilseed crops. These samples will be weighed and dried to determine their water content and compute the amount of water consumed by each oilseed over the 2014 growing season.
Kate Reardon collaborated with ARS technician Aron Boettcher to develop an in house method for quantifying glucose and sucrose sugars in nectar from canola flowers. Shown above Aron Boettcher and Hayley Peter-Contesse prepare pollinator exclusion bags.

- Everyone is engaged in harvest of experimental plots of various cereal and oilseed crops under conditions that are hot and dry.
Steve Umbarger and Mandy Wuest operate a small plot combine for harvesting the numerous plots of wheat, triticale, barley, carinata, and canola within a cropping systems study west of Pendleton. July 17, 2014.
- Hero Gollany is preparing for wheat bundle harvest in the long-term no-till plots and GRACEnet experiments, and is completing a book chapter on Soil Carbon.
Steve Umbarger performs rodweeding during the fallow phase of conventional winter wheat-fallow rotation in the long-term plots. July 16, 2014.
- Nolan Hill, mathematics and physics major at the College of Idaho, will spend the next four weeks working with Dr.’s Stewart Wuest and John Williams in developing a water vapor flux study of tillage and farming practices with the aim of improving conservation of soil water during summer fallow.
