Northcoast Horticulture Supply was founded in 2001 to provide local Humboldt County Farmers with the BEST Service, Selection and Solutions for all of their agricultural needs. NHS has three retail stores located in Northern Humboldt County in California. You can now find Dirty Business Soil Analytics inside of our Eureka location.
We are taking all recommended precautions for essential businesses to keep safe and effectively serve our farming/gardening community. We will offer limited access at times in each open store to help with safe access to the supplies and services we offer.

We sincerely apologize but our Redway location (drop-off spot) is closed. In order to continuing servicing our clients, we recommend that you send your samples using Priority Mail. 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:
852 W. Wabash Avenue

Humboldt Ag Supply will still offer drop-ships to this location – by appointment only – includes the Nutrient Management Programs. Please call 855-707-3276 for more information or to place an order.
