Crop Producers, agronomists, gardeners, homeowners and anyone else who is thinking about taking soil samples this fall or next spring need to be aware that South Dakota State University no longer offers commercial testing (Effective Oct, 2011). Below is a list of nearby state or private laboratories that can be used for crop production fields, gardens and lawns. The private laboratories are not necessarily recommended or endorsed, however many will give university recommendations when asked. Crop producers, agronomists, gardeners, and home owners with questions on sample submissions, analysis charges and recommendations should contact the laboratory of interest.
