Abstract Using a computerized tree growth simulator for old-field plantations, this study reaches tentative and preliminary conclusions about loblolly pine (Pinus taeda L.) plantation management systems which maximize rotation-start present value under various situations. Assumptions included different product mixes and prices; interest rates; planting spacings; harvest ages; and intensity, frequency, and timing of thinnings.

Abstract Stem analysis data were used to examine volume, height-dbh, form and taper relationships for loblolly pine (Pinus taeda L.) trees grown in unthinned old-field plantations, cutover-site plantations, and natural stands. Results showed significant differences in volume, height-dbh, tree form and taper relationships for loblolly pine grown in stands from these three origins. Thus, in order to accurately predict total and merchantable volumes as well as upper stem diameters and heights, forest managers should apply separate volume and taper equations for each stand class.

Plant Control

Abstract Through 11 years, fertilization at planting significantly increased the stemwood volume (outside bark) per loblolly pine (Pinus taeda L.) on an intensively prepared moderately well-drained fine sandy loam site in northern Louisiana. Four years of herbaceous plant control significantly increased pine survival, and because herbaceous plant control increased survival, it resulted in a significant increase in total stand volume. Woody plant control no longer produced significant results by age 11. South. J. Appl. For. 14(4):173-177.

Volume Equations

Abstract It has been suggested that the many published loblolly pine (Pinus taeda L.) volume equations be consolidated. Comparative analysis demonstrated that a single volume prediction system can be used to estimate total and merchantable volume for old-field plantation-grown loblolly pine through much of its range. Three data sets were pooled to produce total volume equations and ratio equations for merchantable volume. These equations will be particularly useful in areas for which no volume tables have been specifically prepared.

Abstract Herbaceous weed control influenced the growth of planted loblolly pine (Pinus taeda L.) over a 10-yr-period. Five treatments were examined: (1) Untreated control: seedlings were planted in the established herbaceous vegetation; (2) Glyphosate: glyphosate was broadcast in September 1981 before planting; (3) Disked: plots were cross-disked in September 1981 before planting; (4) Glyphosate-PPWC: glyphosate was broadcast before planting as in Treatment 2, and postplant weed control (PPWC) herbicides were broadcast yearly for 4 yr (1982, atrazine plus simazine ; 1983, atrazine plus oxyfluorfen; 1984 and 1985, hexazinone ); and (5) Disked-PPWC: plots were disked before planting as in Treatment 3, and the PPWC herbicides were broadcast as in Treatment 4. Four years of PPWC did not affect survival and resulted in greater height, dbh, and volume per loblolly pine through 10 growing seasons. The disked-PPWC plots were the most productive through 8 growing seasons, but higher than average mortality after 8 yr on the disked-PPWC treatment resulted in the glyphosate-PPWC plots producing more volume per acre after 10 growing seasons. Total volume production was 253 inside bark ft³/ac greater on the two PPWC treatments than on the untreated controls. South. J. Appl. For. 18(3): 105-109.

Fertilization Effects

Abstract Effects of precommercial thinning and subsequent fertilizing on white-tailed deer (Odocoileus virginianus) forage in a loblolly pine (Pinus taeda L.) plantation, at ages 7 to 9 years, were studied in the upper coastal plain of Alabama. Based on pooled means, total deer forage available in August (1977-79) was significantly greater (P < 0.05) on thinned plots (515 lbs/acre) than on plots unthinned (283 lbs/acre). Pooled means of February (1978-80) samples showed a significantly (P < 0.05) greater abundance of deer forage on thinned (38 lbs/acre) than on unthinned plots (14 lbs/acre). An application of urea (329 lbs/acre) in March 1978 apparently increased deer forage on thinned (790 lbs/acre) and unthinned plots (431 lbs/acre) in August 1978. Fertilization effects on deer forage were still evident in the February 1979 sample on thinned and unthinned plots but were not evident the following August.

Abstract Four equations were compared for predicting mortality after thinning in old-field loblolly pine (Pinus taeda L.) plantations. The model selected is of the form: N2 = [N1a1 + a2(A2a3 - A1a3)] 1/a1 where N1 and N2 denote trees per acre at ages A1 and A2. Survival curves for thinned, old-field loblolly pine plantations in Coastal Plain and Piedmont Virginia are given.

Abstract Surface drainage created adequate conditions for survival and growth of loblolly pine (Pinus taeda L.) on most sites within a wet lowland area. Successful pine establishment occurred on soils having loamy or sandy surface horizons and where original forest cover had been pine-hardwood or hardwood. On a lesser but significant number of sites, however, loblolly pine had unsatisfactory survival. Such problems were common where clay content of surface soil was high and the water table remained near the surface after ditch installation. In most cases, these conditions occurred on sites formerly occupied by cypress-hardwood timber. Planted sweetgum (Liquid ambar styraciflua L.) and baldcypress (Taxodium distichum (L.) Rich.) had better survival than loblolly pine on these sites. Guidelines for delineating such problem sites are given and management alternatives discussed.

Pinus Taeda L

Abstract Ninety-four trees were measured by two crews with six height-measurement methods in a loblolly (Pinus taeda L.) pine plantation. The Suunto clinometer with tape was most precise; however, it was also biased. Two methods using the Christen hypsometer were faster than the three methods based on measured horizontal distance and a method using a vertical pole and a hypsometer. In addition to technique selection, crew selection, training, and supervision were important.
