Subsoiling and Reduced Radial Growth in Seed Orchard Loblolly Pine Established on Sandy Soils
Mean radial increment growth rates of healthy subsoiled and nonsubsoiled loblolly pines were compared to declining subsoiled and nonsubsoiled trees in a seed orchard located on sandy soil. Following subsoiling during adverse climatic conditions, declining and healthy subsoiled pines demonstrated a progressive reduction in radial increment growth when compared to their respective controls. Three years after subsoiling, healthy and declining subsoiled trees grew significantly more slowly than their controls. Implications for seed orchard management are discussed.
