For the LTER deep core soil samples, a sieved soil sample from each treatment, sampling station, and soil depth is oven dried at 60 degrees C for at least 48 hours until no further mass loss occurs. Air dried soil can also be used. The sample is then pulverized to a fine powder using a swing mill pulverizer (similar to a ball mill) and placed into polyethylene vials for storage.
