MCSE: Soil C and N


see KBS029-prot01


Sampling Frequency: Annually through 2001

Total soil carbon and nitrogen are analyzed using the same basic methodology as total plant carbon and nitrogen. Subsamples from the composite soil sample from each plot in April are air-dried or oven-dried at 60 degrees C for 48 h. Duplicate subsamples (10 mg) from each dried sample are then finely ground in a roller mill, weighed into tin foil cups and analyzed for C and N using a CHN analyzer.
