However, a brief review of the literature shows that results of trial applications of fertilizers are still inconclusive and vary widely with species and sites. In fact, under certain conditions, the response to fertilization may produce results contrary to those desired. This proved the case in a 5-year study aimed at increasing cone production in a young loblolly pine (Pinus taeda L.) seed production area in southern Illinois.
