I was just reviewing my mediocre results from Auburn and wondered this same thing.

 

Waypoint result chart is nice.

 

I've been using Waypoint for the last few years. The S3M test gives the important data points and their recommendations seem sound.

 

Another vote for Waypoint!! I really like their format and they give you all the info you really need with an S3M test and it's only $16.50. They are also super fast as I got results from mine the day after they received it in the mail. They are super friendly too when you call.

 

If you go with Waypoint, @g-man recommends using the Memphis lab. If you have high pH, use the SW1 test. For low pH use the S3M.

I've been using the Richmond lab, no complaints.

 

I too have used the Richmond Waypoint lab and have no complaints (and also no complaints about VA Tech). However, the Richmond lab does only the S3M, which is fine for acidic soils but not alkaline ones. I suspect San Diego has alkaline soil. The Tennessee Waypoint does S3M but also the SW1 test which is appropriate for alkaline soils. I included Ridgerunner's information on picking labs because he goes into the details of using appropriate extractants. It's nice if the soil test results are easy to read but more important that they give the best information for your kind of soil.

 

Thank you all! I will give Waypoint a try. @Virginiagal thanks for the additional guidance regarding which test to choose based on pH.

 

To find the form, look under Resources, then Submittal Forms, then Waypoint Tennessee, then Western Soil Sample. On the form SW1 is one of the columns and that's the one to mark. You probably have to call to get the proper amount to pay. There are directions on taking soil samples but you have to look around to around to find it,
