Abstract
The use of clearcut and burn and clearcut and leave site preparation techniques were investigated to determine their influence on nutrient distribution and seedling development in a pine plantation. The study site was located on a sand ridge in Newton County, Texas. The soils were loamy sands belonging to the Rosalie and Darco series, a complex of Arenic and Grossarenic Paleudults. The site was clearcut in January 1976, and six plots were established and paired for study. The three burn plots were treated in March 1976. Logging debris was sampled prior to burning and at one and two year intervals following treatment. Soil samples were obtained to a depth of 91 cm immediately after treatment and one and two years later. Chemical analysis of the plant and soil samples for N, P, K, Ca, and Mg, followed standard techniques. Soil organic matter was determined by the Walkley-Black method. Ninety-six seedlings were planted on each of the six plots in March 1976. Height and survival measurements were made at monthly intervals during the first and second growing seasons following out-planting. Seedling foliage was analyzed for N, P, K, Ca, and Mg by standard methods at the end of each growing season. Seedling survival and height growth were unaffected by treatment through the two years of the study. Survival averaged 80% the first growing season and 59% the second. Seedling height averaged 30 cm and 48 cm at the end of the first and second growing seasons, respectively. ...
