Land and Resource Management on Typic Quartzipsamments

TL;DRAbstract

Survival and growth of seven species/treatment combinations were tested on Tonkawa fine sand (thermic, coated Typic Quartzipsamment) in Nacogdoches County, Texas. In January 1983, seedlings were hand-planted on an intensively prepared clearcut site on the Tonkawa soil series in northern Nacogdoches County. Tonkawa sands serve as recharge zones for the Carrizo aquifer, a major source of clean groundwater for much of East Texas. Intensive management practices on this sensitive site created severe site conditions, providing incentive for the study. Species/ treatment combinations were: untreated loblolly (Pinus taeda L.) pine (LOB/CON); Terra-SorbTM -treated loblolly (LOB/Tm);olin clay slurry-treated loblolly (LOB/CLA); untreated slash (P. elliottii Engelm.) pine (SLA/CON); Terra-Sorb-treated slash (%A/ TBR); kaolin clay slurry-treated slash (SLA/ CLA); and containerized longleaf pine (P. alustris Mill.) (LL/CONT). Treatments were applied as a bareroot+up prior to planting, to increase so
