A sample of the garden soil was submitted to the Cornell Nutrient Analysis Laboratory to test for heavy metals that might pose a toxicity threat to humans or adversely affect plant health. The test results showed that the metals levels in the soil are below what is considered toxic to humans or crops.
Cornell's Recommended Maximum Safe Concentrations for Garden Soils:
Arsenic (As): 16 mg/kg
Barium (Ba): 350 mg/kg
Cadmium (Cd): 2.5 mg/kg
Chromium (Cr): 36 mg/kg
Copper (Cu): 75 mg/kg
Nickel (Ni): 40 mg/kg
Lead (Pb): 400 mg/kg
Zinc (Zn): 150 mg/kg
