Microbial biomass at the Coweeta Hydrologic Laboratory in 1994

All of the data originated in the riparian watershed (WS 55) at Coweeta. Thus far, all soil data occurred in 1994 - ie. before the rhododendron removal. The summary C and N files are saved by date (year, month,and day). Within each file are data for Microbial carbon and nitrogen. The sample names (ex. C1-1, 0-5) indicate control plot, 1 meter distance from the stream, sample number 1, at the 0-5 cm soil depth, and so on. T would indicate treatment plot and 5-10 indicates the 5-10 cm soil depth. Within each plot (C and T), we established three transects, 10 meters in length, at 1, 5, and 15 meter distances upslope from a stream. Along each transect, 4 samples were collected and each sample consisted of two bulked soil cores, separated by depth (0-5 cm and 5-10 cm). All sampling dates were in 1994, beginning in March. Sample dates were selected to correspond with seasonal changes and occurred March 25, June 16, August 16, November 1, and December 16. Microbial C data is listed as microgram C per gram dry weight soil, followed by an average of C (measured by distance from the stream) and standard deviation corresponding to that average. ND listed in the Project indicates that the sample needs to be reanalyzed or was missing. The december Project needs more work, but I have included it anyway. Microbial nitrogen is listed as microgram of total persulfate N per gram dry weight soil. This is again followed by an average N value by distance from the stream and depth of the soil and the corresponding standard deviation.
