To all Seed Analysts, Seed Technologists, and Seed Control Officials,
Now available is the AOSA Special Tolerances Computer Program for automatically calculating purity tolerances of seed mixture using Tables 14D and 14E. In consultation with the AOSA Purity Subcommittee and the AOSA Statistics Committee, the program was developed by Andrew Meyer, a Computer Science major at California State University, Sacramento. Since the 2015 AOSA/SCST Annual Meeting, two rounds of beta testing have been conducted. Based on comments received, the special tolerance calculation program has been upgraded significantly adding a more extensive user guide and the automatic tolerance determination using Table 14B in cases when particle-weight ratio is 1.45 or less.
Data you will need to supply when using the program:
Please e-mail Andrew (firstname.lastname@example.org) if you have any questions or comments about the program. Please include me as a ‘cc’ on your email so I can track comments and questions.
Also, to avoid confusion, if you participated in prior beta testing rounds please remove the old version of the program from your computer and discard the CDs.
For folks that are unable to download the program file from the website due to IT policy restrictions at your worksite, please contact me and I will provide the program file on a CD.
Good luck with your Special Tolerance calculations!
