Abstract
  • There are many diagnostic approaches to evaluate the nutritional status of a forest stand. "Inference based on site and stand characteristics, visual symptoms, and foliar analysis are suggested to have the greatest utility in routine evaluations, while soil analysis and pot trial techniques should primarily be regarded as research tools (Carter, 1992)." Field trials are the ultimate proof that a stand will respond to fertilization. Fertilization trials should be carefully designed to aid in predicting response from stands where field trials have not yet been evaluated. Although this section is useful for selecting stands for fertilization, its focus was diagnosing nutrient deficiency. Once a deficiency is diagnosed, the next step is to determine whether the particular site in question is likely to respond to fertilization. What is the probability of response? More detailed knowledge including strategic, biological, and operational considerations of nitrogen fertilization must now be built. Subsequent sections will attempt to build this foundation with the ultimate goal of providing the knowledge to successfully establish a large-scale fertilization program.
