Soil Test Company



Can anyone recommend a reputable soil test company? I live in Northern California.
Thank you!


IAS Laboratories offers soil testing.

You might contact your local university cooperative extension service. Many do soil testing free of charge.



I like to use a soil test kit from Lowe’s. If you follow the directions on the package, you will have accurate results in 8 hours or less.

I use this along with a soil Ph meter for best results.
