If you would like to have soil or plant samples analyzed by the SDSU Soil and Plant Testing Laboratory, please send the samples, along with completed information sheets and payments:
Soil Testing LaboratoryThe Soil Testing Laboratory is located in Agricultural Hall on the SDSU Campus. Check out the SDSU Map for more information - Ag Hall is building #4 (somewhat to the left center of the map). To get to the lab, enter Ag Hall through the North doors and walk straight ahead - we're located on the basement floor - room 07.
