Cornell Nutrient Analysis Laboratory (CNAL) participates in the North American Proficiency Testing (NAPT) program. This program is managed by the Soil Science Society of America and assists soil, plant and water testing laboratories in their performance through inter-laboratory sample exchanges and a statistical evaluation of the analytical data. We also validate our analyses using National Institute of Standards and Technology materials. Specific questions regarding methodology can be directed to Dr. Michael Rutzke, Director of CNAL

Heavy Metal Screening: Testing for heavy metals is available for situation where soil contamination is suspected, or as a precautionary measure. Heavy metals accumulate in soils at low levels naturally, but toxic levels can be reached as a result of mining, manufacturing, and industrial activities. Contact with heavy metals is dangerous for humans and animals, but can also have adverse effects on plants and soil organisms. Metals falling under this category include cadmium, chromium, lead, copper, nickel, and zinc. To extract heavy metals, a soil sample is digested using acid; quantification of metals in extracts is then performed using Inductively-Coupled Plasma (ICP) atomic emission spectroscopy. Use Soil Analysis Submission Form for this test.
