The Cornell Nutrient Analysis Laboratory (CNAL) is closed and is no longer accepting samples.

The Cornell Soil Health Lab is open and analyzing more and more samples every year.  Learn more about their  suite of soil health testing services.

Several land grant institutions in the Northeast have analytical labs that offer testing services formerly offered by CNAL.  They include:

Penn State’s Agricultural Analytical Services Laboratory provides these testing services

  • Soil testing
  • Water testing
  • Plant analysis
  • Compost testing
  • Biosolids testing
  • Green roof media testing
  • Greenhouse (soilless) media testing

The University of Maine’s Analytical Lab and Maine Soil Testing Service analyzes:

  • Soil
  • Plant tissue
  • Compost
  • Manure
  • Irrigation water
  • Wood ash
  • Fertilizers
  • Organic residuals and other materials

Note that the above facilities offer routine analytical analyses. Researchers desiring “modified” analytical services will need to contact the analytical staff for advice on the lab capabilities.
