Density Results

Abstract Soil bulk densities, determined on plots representing a gradient of harvesting traffic, indicated that compaction was an average of 12 percent greater on former logging decks and primary skid roads as compared to nontrafficked areas. Penetrometer readings supported the bulk density results and, in addition, showed increased compaction on secondary roads and road borders as compared to relatively undisturbed areas. This compaction was reflected in height growth reductions of 39 to 59 percent in five-year old loblolly pine (Pinus taeda L.) on decks and primary roads. Number of pine per acre was reduced by 88 to 91 percent on the same areas. Root collar diameters also decreased but were not significantly different from those on relatively undisturbed plots. These results are discussed in relation to the 1 percent proportion of the harvested area involved in soil property impacts and reduced tree growth.

Abstract Growth response of loblolly pine (Pinus taeda L.) to bedding and phosphorus fertilization was determined on three sites classified as moderately well, somewhat poorly, and poorly drained. Ten-year growth in terms of height and diameter showed a pronounced response to treatments on the poorly drained site but only a small response on the other sites on which competition was eliminated as a factor in all treatments. Bedding and fertilization interacted only on the poorly drained site where response to bedding was most pronounced. Our projection of height over age curves for individual treatments suggest that response to phosphorus alone may compare favorably with bedding plus phosphorus after the pines are about age 20 on the poorly drained site. Nutrient concentration in foliage alone was not indicative of the differential growth response to fertilizer obtained over drainage classes.

Abstract Twenty-two-year-old loblolly (Pinus taeda L.) and slash pine (P. elliottii Engelm. var. elliottii) research plantations were clearcut-harvested and replanted with the same species. The objective was to compare tree growth between the two rotations. Seven growing seasons into the second rotation, loblolly and slash pines averaged an 8- and 3-ft reduction in total height, respectively. Height growth of loblolly pine was especially reduced on replanted plots that had been harrowed or harrowed and bedded 22 yr earlier, but the reduction in growth occurred on the burn-only (check)plots as well. The reasons for these growth declines were not identified, but it was unlikely that differences between rotations in rainfall patterns, logging damage, or competition were responsible. South. J.

Control Study

Abstract A simple competition assessment system was evaluated as part of an intensive competition control study in a natural, even-aged stand of loblolly-short-leaf pine (Pinus taeda L.- P. echinata Mill.) seedlings in southern Arkansas. Four levels of competition control were maintained annuallyfor 3 years as follows: (1) no competition control, (2) woody competition control, (3) herbaceous competition control, and (4) total control of nonpine vegetation. The competition assessment system is based on a correlation of total height to groundline diameter (gld) for loblolly pine seedlingsthat are less than 6 ft tall. The correlation indicated that if seedling gld's are not within + 10 mm of total seedling height (in feet) multiplied by 10, then the seedlings would most likely show a positive growth response to competition control.

Abstract By comparison with any o several stocking standards, loblolly pine (Pinus taeda L.) stands infested with southern pine beetle (Dendroctonus frontalis Zimm.) on the Kisatchie National Forest, Louisiana, were frequently overstocked. Stocking levels associated with reduced stand and tree growth and frequent intermittent water deficits also enhance successful southern pine beetle attack. Charts that help determine how well existing stocking meets management objectives are also useful for judging stand vulnerability to the southern pine beetle.

Density Study

A study was established with loblolly pine (Pinus taeda L.) planted at 1683 trees/ha competing with sweetgum (Liquidambar styraciflua L.), water oak (Quercus nigra L.), or loblolly pine at densities of 0, 1794, 2692, and 5382 trees/ha. The study is a split-split plot with three blocks. Main plots are the three competitor species; subplots are with or without 2 years of herbaceous vegetation control (HVC); and sub-subplots are competitor densities. The study was measured at 6 years after establishment. Pines in pure plots responded to HVC with a mean basal area gain of 1.8 m2/ha (13%). With HVC, basal area increased 2.7 m2/ha (70%) for sweetgum and 2.3 m2/ha (58%) for water oak. Pines in mixed plots did not respond, or responded negatively, to HVC. Pine height, basal area, volume index, and canopy projection were only slightly affected by sweetgum density above zero. Pine characteristics decreased as water oak density increased. Adding sweetgum or water oak to pine reduced total (pine + hardwood) volume index and basal area.
