Samples of forest components that are normally burned or removed during harvest were collected at the Coram Experimental Forest and the Lubrecht Experimental Forest and analyzed for elemental content. The elements calcium, copper, iron, potassium, magnesium, manganese, nitrogen, sodium, phosphorus and zinc in standard fuel-size categories were analyzed to help assess how much of these nutrients would be lost during harvesting or fires of different intensities. The data can be used to describe the essential nutrient content in forest biomass and for modeling. The proportioned weights and nutrient contents of vegetation examined in other studies can be related to the nutrient content of vegetation reported here. Estimates can be made of nutrient losses caused by harvesting and slash burning. Many of these procedures are complex, but the measurements and calculations can be invaluable when dealing with problem soils.
