Once we receive the samples, we can then contact you andinquire about any questions or comments you may have.  As a token of our continued appreciation, we will deduct the shipping cost from your analysis. Alternatively, you can drop off your soil sample at Northcoast Horticulture Supply in Fortuna, off the 12thstreet exit. NHS will then expedite the sample to the DBS lab in Eureka and get the process started.

Please mail samples to:
