Soil testing labs listed by SDSU Extension

Soil testing Commercial

SDSU no longer does commercial soil testing. Its Extension page (updated April 11, 2025) lists labs that test by mail. SDSU says private labs are not necessarily recommended or endorsed, but many will give university recommendations when asked. The page does not say which labs take home-garden samples, so ask the lab. South Dakota: AgLab Express, Nisland, (605) 257-7637; Next Level Ag, Alpena, (605) 849-5227, nextlevelag.com.
