An Oakfield Soil Sampler, with a coring diameter of 3/4" (19.05 mm) is used to obtain soil. Litter is scraped off of the surface prior to inserting the tube. Soils are sampled to a depth of 5 cm at all upland sites. A composite sample is obtained by taking ten 5 cm cores along each of the vegetation transects and mixing these together in plastic zip-closed bags.
All samples were stored at 5-10 oC until they could be processed. The samples were sieved through a #5 U.S.A. Standard Testing sieve (4 mm opening). All visible rocks and large root fragments are subsequently removed from the sieved soil. Sorting takes approximately 20 minutes for each composite sample. Sieved soil is returned to the plastic sampling bag and submitted to the K.S.U. Soils Testing Laboratory for chemical analyses. Upon completion of analysis, any remaining soil is returned to KSU Biology for archival storage.
Bulk density data are obtained from the individual cores placed in soil tins. These are air‑dried and weighed, sieved (as above) and reweighed, then dried at 105oC and weighed a final time. No chemical analyses are performed on these samples.
