Can test results be converted from one system to another, such as AOSA to AOSA/EC (OECD) or Crop and Weed to OR Sod Quality?

Yes. Crop and weed exams can be converted to sod quality (SQ) for most species, UGS, or Canada exams in most cases. For example, a crop and weed exam on Tall fescue can be converted to SQ, UGS or a Canada exam with no additional testing required. SQ can be converted to UGS or Crop and Weed certificates in most cases. See the price list for conversion pricing information.
