Guide to Prohibited, Domestic Regulated and Quarantine Soils

The Cornell Soil Health Lab has three categories of regulated soils: Prohibited, Domestic Regulated and Quarantined.

All samples being shipped to the Cornell Lab, regardless of the category, need to be double bagged prior to packaging and shipping. Packing material such as crumpled paper or bubble wrap must be placed in the box with the samples to minimize sample movement and spillage during shipping.

Prohibited Soils:

There are certain counties in the US where soil should neither be packaged nor shipped, these are considered prohibited soils. Soil received from these counties will be destroyed in our lab without processing.
