Title:     Nitrogen mineralization in 6 plots of E133, Fire effects on structure
           and function of oak savanna/woodlands
Principal Investigator:	Dave Wedin
LTER:      Cedar Creek Natural History Area
Date Set:  e13312.tab (Nitrogen mineralization by plot)
Project:   E133
Years:     1995, 1996, 1997, 1998

Description: In situ estimates of nitrogen mineralization rates for 6 permanent
             plots from 1995-1998. In 1995, 1996, and 1997 incubations were done
             from mid-May to mid-June, mid-June to mid-July and mid-July to 
             mid-August.  In 1998, only the mid-May to mid-June incubation was 
             done.  Therefore, 98aveiNO3, 98aveiNH4, and 98aveiH20 are from the 
             initial data for May to June only.
