Description
Diameter growth response functions were developed using data collected from nitrogen fertilization study plots in eastern white pine stands on till and outwash soils. These functions were combined with height measurements and used to evaluate stand volume and value growth. White pine diameter growth functions were developed for application rates of 0, 50, 100, and 200 lb of nitrogen/ac, but only those for the 0 and 100 lb/ac treatments were compared because it was evident that the 100 lb/ac treatment would provide a larger financial return than either 50 or 200 lb/ac. The mean increase in sawtimber volume due to fertilization with 100 lb of N/ac was 1,226 bd ft/ac for stands on the till soils and 775 bd ft/ac for stands on the outwash soils. Increases in studwood volume were 293 and 172 bd ft/ac, respectively. The average stand value increase due to fertilization, with a sawtimber price of $100/thousand bd ft and a studwood price of $50/thousand bd ft, was $135/ac on the till soils and $87/ac on the outwash soils.
