Title:

Nitrogen and Phosphorus Fertilization Applied in a Subsoil Slit at Time of Planting Loblolly Pine - Ninth Year Results, 1989 (Charlottesville Research Center Research Report No. 85)

Description:

A complete factorial of nitrogen (0, 100, and 200 lbs N/acre) and phosphorus (0, 50, and 100 lbs P/acre) applied 8 to 10 inches below ground in a subsoil slit, was installed on a hardwood conversion area in Buckingham County, Virginia during May 1979. Loblolly pine survival and heights were tallied initially and then after 1, 2, 5, and 9 growing seasons and diameter at breast height after 5 and 9 growing seasons. Nitrogen fertilization did not significantly influence height or DBH. Phosphorus fertilization produced a positive and significant increase in height and diameter at all measurement ages. When applied alone, there was a linear response to phosphorus. Applying nitrogen below ground at planting does not appear to enhance growth. New field studies should be initiated to identify the soil/site factors which are important in dictating loblolly pine response to below-ground phosphorus fertilization at planting.
