No. 113 Controlling Herbaceous Competition and Tip Moth - Effects After 16 Years; by T. A. Dierauf and J. A. Scrivani

No. 113 Controlling Herbaceous Competition and Tip Moth – Effects After 16 Years; by T. A. Dierauf and J. A. Scrivani

November 3, 2020 - Report describes the effects of four treatments – herbaceous vegetation control, tip moth control, herbaceous vegetation and tip moth control combined, and no treatment – on loblolly pine growth through age 16. Herbaceous control increased height by 2 feet, diameter by 0.5 inches, and basal area by 25 square feet. Tip moth control had only slight effects on those attributes.

No. 082 Root Pruning White Pine Seedlings Prior to Planting; by T. A. Dierauf and H. Hannah

No. 082 Root Pruning White Pine Seedlings Prior to Planting; by T. A. Dierauf and H. Hannah

November 3, 2020 - Report provides results from six separate studies installed between 1980 and 1984 to test root pruning of white pine seedlings to lengths of 1, 3, and 5 inches compared to unpruned seedlings. Severe root pruning (to 1 inch) reduced survival by 60-75%, and pruning to 3- or 5-inch lengths reduced survival to lesser amounts. Surviving seedlings did not differ in height growth regardless of severity or pruning.

No. 083 Early Planting, Over-Winter Storage, and Late Planting of White Pine Seedlings; by T. A. Dierauf

No. 083 Early Planting, Over-Winter Storage, and Late Planting of White Pine Seedlings; by T. A. Dierauf

November 3, 2020 - Report summarizes results from a study installed from 1981-1984 to evaluate early lifting/planting, over-winter storage, and late lifting/planting of white pine. The most significant effect on survival came from storage; seedlings lifted and planted in the fall or in the spring survived equally. Height growth of surviving seedlings was not affected by lifting/planting schedule.

No. 084 Loblolly Pine Release Study Report No. 13; by T. A. Dierauf

No. 084 Loblolly Pine Release Study Report No. 13; by T. A. Dierauf

November 3, 2020 - Report summarizes findings from plots comparing release from hardwood competition by basal spraying herbicides at two dilution rates at age one to no treatment and measured through age 17. Herbicide plots averaged 68-70% more basal area and 91-99% more volume than check plots.

November 3, 2020 - Report summarizes findings from plots comparing release from hardwood competition by aerial application of herbicides at age four to no treatment and measured through age 16. Herbicide plots averaged 22% more basal area and 35% more volume than check plots.

November 3, 2020 - Report summarizes findings from plots comparing release from hardwood competition by aerial application of herbicides at age four to no treatment and measured through age 19. Herbicide plots averaged 31% more basal area and 53% more volume than check plots.

No. 087 Loblolly Pine Release Study Report No. 16; by T. A. Dierauf

No. 087 Loblolly Pine Release Study Report No. 16; by T. A. Dierauf

November 3, 2020 - Report summarizes findings from plots comparing release from hardwood competition by aerial application of herbicides at age three to no treatment and measured through age 15. Herbicide plots averaged slightly less basal area and only 0.4 cords per acre more volume than check plots.

November 3, 2020 - Report summarizes findings from plots comparing release from hardwood competition by basal spraying herbicides at two dilution rates at age one to no treatment and measured through age 18. Herbicide plots averaged 10-16% more basal area and 13-23% more volume than check plots.
