The Technology Extrapolation Domains (TED) Framework shown on the maps below display spatial units with shared soil and climatic properties where agronomic tools and products might perform similarly if all other farm management variables are the same. Each spatial unit is represented by a different color and by a six-digit number.

The six-digit TED numbers associated with ESN® trial locations are presented in the table below the maps. These numbers can be used to determine if TEDs in which ESN® trials were performed correspond to TEDs in your own farm or region. Visit the TED Framework tool page and review the tutorial to learn how to use the TED Framework.
