Soil Properties and Pine Growth Affected by Site Preparation after Clearcutting
A pine-hardwood sawtimber stand in southeast Texas was clearcut in September 1972. Random plots were burned, chopped, KG-bladed, or left untreated. In the spring of 1974, 1-0 loblolly pine seedlings (Pinus taeda L.) were handplanted at 8 by 10 foot spacing. Data from soil samples, taken from the 0-5 inch depth before clearcutting and 1, 3, and 5 years after site preparation showed that burning appeared to have changed soil nutrient levels the least. Of the two mechanical treatments, KG-blading altered the chemical composition of the soil most, probably because topsoil organic matter was removed. Planted pines survived and grew best on mechanically prepared areas, producing 1.5 to 3.3 times more cubic-foot volume per acre than either of the other treatments by the end of the eighth year.
