To evaluate site preparation effects on loblolly pine five years after stand establishment in east Texas, trees/acre, d.b.h., total height. and total biomass were measured on four treatments: clear-fell, burn, chop and burn, and shear/pile and disk. Treatment effects on production were not statistically significant (α = 0.1), but two points were evident: (1) more intensively prepared sites had better stem distributions, and (2) the height variation component due to soil was larger than the treatment component. Bulk densities indicated no significant compaction; soil chemical properties for the mechanical treatments were similar to the clear-fell treatment. Foliar and stemwood Ca, Mg, K, P, N were similar for all treatments. Adverse effects of the mechanical methods on site productivity were not evident when compared to the clear-fell treatment.
