“…However, nutrient concentrations of plant parts, Pinus sylvestris, (e.g. needles, wood) have not been observed to show a decreasing trend with stand age (Helmisaari 1990, Helmisaari 1992, Augusto et al 2000). The ratio of stand level needle mass to fine root mass, often interpreted as an indicator of nutrient availability (Santantonio 1989), has also been observed to be relatively independent of stand age in Pinus sylvestris (Vanninen and Mäkelä 1999).…”

Vanninen, P. 2004. Allocation of above-ground growth inPinus sylvestris -impacts of tree size and competition. Silva Fennica 38(2): 155-166.The effect of tree age, size and competition on above ground growth allocation was studied with 69 Pinus sylvestris trees. Competition was described by tree-level indicators (needle density, crown ratio and height-diameter ratio). The stem, branch and needle growth were determined by stem and branch radial increments and tree level biomass analysis. Combined growth of compartments was strongly correlated with needle mass. Furthermore, tree age, size and competition indicators affected the allocation of growth among the compartments. The allocation of growth to stem and needle increased with tree age and size while the allocation of growth to branch decreased. The increasing crown ratio increased allocation of growth to branches. The combined growth of the components and separate growth of needles, branches and stem were related to needle mass. However, competition and tree size were significant additional explanatory variables when the stem, branch and needle growth were estimated according to needle mass. The growth efficiency increased with relative tree height and decreased with increasing needle density. Allocation of Above-ground Growth in Pinus sylvestris -Impacts of Tree Size and Competition

“…WTH causes greater nutrient removals than SOH because nutrient concentrations are generally higher in foliage and branches than in stems (Mälkönen 1974;Mälkönen and Saarsalmi 1982;Kubin 1983;Finér 1989). The developmental stage of the stand, in turn, affects biomass allocation and nutrient contents (Mälkönen 1974;Helmisaari 1995;Augusto et al 2000). The proportion of nutrient-rich crown and bark out of the total biomass decreases as a stand ages (Albrektson 1980;Hakkila 1989;Vanninen et al 1996) and accordingly also the nutrient amount per unit of stem and total biomass (Augusto et al 2000).…”

Whole-tree harvesting (WTH), where logging residues are removed in addition to stems, is widely practised in Fennoscandian boreal forests. WTH increases the export of nutrients from forest ecosystems. The extent of nutrient removals may depend on tree species, harvesting method, and the intensity of harvesting. We developed generalized nutrient equations for Scots pine (Pinus sylvestris L.), Norway spruce (Picea abies Karsten), and birch (Betula pendula Roth and Betula pubescens Ehrh.) stands to be able to calculate the amounts of nitrogen, phosphorus, potassium, and calcium in stems and aboveground biomass (stem and crown) as a function of stand volume. The equations were based on Fennoscandian literature data from 34 pine, 26 spruce, and 5 birch stands, and they explained, depending on the tree species and nutrient, 61-99% and 56-87% of the variation in the nutrient amounts of stems and above-ground biomass, respectively. The calculations based on the equations showed that nutrient removals caused by stem-only harvesting (SOH) and WTH per harvested stem m 3 were smaller in pine than in spruce and birch stands. If the same volume of stem is harvested, nutrient removals are, in general, nearly equal at thinnings and final cuttings in SOH, but larger in thinnings than final cuttings in WTH. If the principal aim is to minimize the nutrient removals per harvested stem m 3 , the harvesting should be done at mature pine stands. The effect of biomass removal on overall site nutrient status depends on site-specific factors such as atmospheric deposition, weathering of minerals, and the size of the nutrient pools in the soil.

Persian ironwood (Parrotia persica) is native species from Iran and covers 10,54% of the commercial volume. Its wood structure and its chemical composition are affected by growth conditions. The aim of the study was to assess the variation of mineral content (Ni, Fe, Cu, Zn, Pb, Cd), wood density and chemical properties (cellulose, lignin, ash and extractive) of ironwood in relation to altitude above sea level (100, 500 and 700 meter) and pith distance within stem (near to pith and bark and middle point). In addition was investigate the relationship between mineral content with oven-dried density and chemical properties. Results showed that Cd, Cu, Fe, Ni and Zn content (except Pb concentration) increased by increasing of altitude and decreased along radial position within stem from the pith to the bark. Lignin, ash and extractive content increased by increasing altitudes from 100 to 700 meter while cellulose decreased. Radial position had not significant impact on the chemical properties. There are significant relationships between mineral content-chemical properties and between mineral content-wood density (except Cu -density). Forward stepwise regression showed that ash and lignin content had important role on the variation of all of mineral content except on Cd.
