Abstract

Growth rates in loblolly pine (Pinus taeda L.) stands can often be increased markedly by applying phosphorus, nitrogen, or nitrogen and phosphorus fertilizers. On phosphorus-deficient Lowe Coastal Plain sites, the growth improvement from phosphorus fertilization of loblolly pine often amounts to an increase in site index (age 25) of 15 feet.Nitrogen and nitrogen plus phosphorus fertilizaion produces 200 to 250 cubic feet of additional wood in the 5 years after application mostly on larger diameter trees.
