Make sure to include account number, soil code, crop codes, and desired analyses on form. 8 sample IDs may be listed on one page of the soil form. Fill shipping box completely with individual samples so the bags won’t move around during shipping. Use newspaper if needed to fill empty spaces. Double-check and make sure the forms in the shipping box match the samples. If you are an individual sending the sample directly to the lab, be sure to include account number or a check made out to Clemson University. Get more information for soil sampling.
