Evaluating subsoiling and herbaceous weed control on shortleaf pine planted in retired farm landThis article is part of a larger document. View the larger document here.
In March 2005, shortleaf pine was planted on retired fields of the Mississippi Agriculture and Forestry Experiment Station in Holly Springs. The objectives were to evaluate subsoiling and herbaceous weed control on first year seedling stocking, survival, and size. First year seedling measurements were made on stocking, survival, and size. Only results for first year seedling survival will be reported here. Subsoil tillage, herbaceous weed control, and control treatments were completed. Treatments were replicated 3 times in a randomized complete block design. The subsoiling treatment was done in December of 2004. The herbaceous weed control treatment was 4 ounces Arsenal AC® + 2 ounces Oust XP® per sprayed acre applied in a 4-foot band over the row in April 2005. In addition, mowing was completed 3 times between rows during the first growing season. Measurements were conducted on a 0.1-acre plot within each treatment. Neither subsoiling nor herbaceous weed control had any significant effect on seedling survival the first year.
