Fertilizer is mixed and spread by hand twice a year,
once in early May and once in late June. Each plot gets the fertilizer
mixture specified by its fertilizer treatment code. For a list of fertilizer
treatments for each plot, see file trmte36. Starting in
the spring of 1992, half of all replicates of each treatment in fields A and B
were assigned to receive no more fertilizer. For a list of treatments stating
whether each plot receives its usual fertilizer treatment or no fertilizer,
see file trmte100.
Light
Light shades, reducing light penetration by 80%, are put in
place over subplots within specific plots (those with light treatment 2) in
spring (mid-April to mid-May) and taken down in mid-October. For a list of
light treatments for each plot, see file trmte36.
Burning
Starting in the spring of 1992, half of all plots in
E011 in field B were burned. These plots will be burned each
spring. For a lit of treatments for each plot, see the treatment layouts in
file trmte100. On May 5, 1995, a wildfire burned all of
the plots in experiment 36 in field B.
