2010 Annual Report
States producing hard red winter (HRW) wheat were ranked based on their total annual winter wheat production (USDA NASS, 2009). Lists of hard red winter wheat varieties produced in each state were obtained from NASS. Varieties that were common to multiple states and/or were available for multiple crop years were given high priority in the selection of test varieties. Other varieties that were popular in specific states were included to provide coverage of all of the leading HRW wheat producing states. Seed producers and vendors with the chosen varieties in stock were identified in each state through various contacts with foundation seed programs and others in each state’s seed industry. The chosen varieties have been ordered and delivered to the University of Kentucky Granular Mechanics Laboratory to undergo compressibility tests.
A terminal elevator in north-central Kansas that has an automated system for grain loading and unloading is being used as a test site to evaluate automated data collection. This elevator uses a commercial system that logs all their transaction data for incoming and outgoing grain. A virtual private network (VPN) system was installed in January 27, 2010 in the USDA-ARS lab to remotely collect daily transaction data. The data obtained through the VPN were analyzed to sort out grain bins that were empty and to monitor filling with incoming wheat. A field exercise was conducted at this elevator on June 10, 2010. The height and hopper dimension of empty bins, with heights ranging from 100 to 120 ft, were measured using a laser distance meter. The height and dimension data were used to draw the grain bin configuration in a computer-aided design (CAD) software package. These measurements provided the empty-bin reference values needed to determine grain volume from future loaded-bin measurements.
Four bins were measured in the USDA ARS research facility in Manhattan, Kansas on June 10-11, two metal bins and two concrete bins. One lot of wheat was measured in the first metal bin. The lot was moved to a second bin where it was first measured peaked, then was measured again after leveling. A 12,000 bu round concrete bin and 1250 bu square concrete bin, each containing wheat, were measured in the research elevator. All distances were measured using the commercial laser distance meter. The grain height and hopper dimensions of empty bins in the research elevator were also measured using the commercial laser distance meter. These data are being incorporated into CAD drawings to compare filled and empty grain bin configurations, giving accurate grain volumes for pack factor calculations.
These activities were monitored via numerous meetings with the cooperator to discuss project plans and review program goals and accomplishments, along with personal oversight of the research, the majority of which was performed in ARS facilities.
