We are looking for recommendations for a reliable (and ideally reasonably priced) Soil analytical lab for environmental (non-agricultural)soil samples. Analyses would include metals (e.g., Ni, Co, Cr) as well as standard OM, N, P,CEC etc. . Analysis would be in extractable units, not totals.
We would be especially interested in recommendations for labs when standards were sent to labs and found to accurately reflect composition of standards. Thanks. Sharon
