Fertilization: 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 trmte04.

Burning: Field D is within burn compartment #6 (106). This field is burned 2 years out of every three. Starting in 1989, two sections in each macroplot were burned in fields B and C. Starting in 1992, two sections in each macroplot were burned in field A as well. These sections are now considered experiment E057. For a list of burn treatments for each plot, see file trmte57.

On May 5, 1995, a wildfire burned several parts of B004 macroplots that were not supposed to be burned. Macroplots 1, 2, 6, 7, and 8 were completely burned.
