Fertilization of A 21-Year 01d Slash Pine Stand

The integration of gum naval stores and wood production suggests the need for knowledge of fertilization for stimulating growth of trees large enough to be “worked” for gum. Associated with this is an interest in fertilization for gum and cone production and seedling development. Hence, this study was installed in a 21-year-old slash pine (Pinus elliottii) plantation in the upper Coastal Plain of Georgia. The soil was low in nitrogen (trace), phosphorus (about 4 ppm P), and potassium (about 5 ppm K). Calcium analyzed medium (about 28 ppm Ca). The pH averaged 5.0.
