Title: Accumulated data from experiment E001, Long-term nitrogen deposition - Effects on plant diversity, composition, productivity, and stability Principal Investigator: G. David Tilman LTER: Cedar Creek Natural History Area Data set: e001.tab Project: E001 Year: 1982-1997 Biomass notes: Biomass sample size = 0.30 m2 Light data notes: - These data are the mean percent light penetration. In 1982 15 observations were made in fields A, B, and C except in field B, plots 37, 41, 44, and 54 and in field C plot 2 where 14 observations were made. In 1983 all plots in field A and plot 1-38 in field B had 4 observations made and all other plots had 2 observations. All other years had 2 observations made per plot. In 1989 Plots 4-F, 7-F, 21-F, 23-F, and 23-B were shaded. Soil moisture/NO3 notes: 1985 - Samples taken 4-26 for fields A and D, 9-20 for field C and D; 2 M Kcl; samples for field D on 4-26 are not given in this file 1986 - Samples taken 7-16 for field A, 7-30 for field B, 8-18 for field C, 8-19 for field D; 2 M Kcl 1987 - Samples taken 7-20 for field A, 7-28 for field B, 8-4 for field C, 8-24 for field D; 2 M Kcl 1988 - Samples taken 8-18 for fields A and D, 8-17 for fields B and C 1989 - Samples taken 8-14; 2 M Kcl 1994 - Samples taken 7-7 for field A, 7-27 for field B, 8-9 for field C 9-19 for field D Addtional biomass notes: Sample size = 0.30 m2 1995 - Originally plot 6,11,12,34,35,37 in field B had Burnt Moss. These were changed to Mosses & Lichens and totaled with Mosses & Lichens where appropriate Label Exp: Cedar Creek experiment number.
