Denotes post-hoc pooling, P>0.25; new F-values are given for those tested against the pooled term. Results of SNK tests are also reported. NB  =  no burial, AC  =  artifact control, CB  =  complete burial, PB  =  partial burial. A1, A2 =  area 1 or 2, S1, S2 =  site 1 or 2, N−  =  no nutrient added, N+  =  nutrient added.
