Forest Tree Nutrition

Abstract This article provides foliar nutrient concentration distributions and sample size calculations for Douglas-fir, grand fir, ponderosa pine, and lodgepole pine. Managers can obtain foliar nutrient values from their own lands and use this information to make judgments on the relative nutrient status of forest stands. Foliage was collected from unfertilized trees at 160 different research sites of the Intermountain Forest Tree Nutrition Cooperative spanning a 16 yr period from 1982 to 1997. Douglas-fir showed the lowest variation in foliar nutrient concentrations, while grand fir was the most variable of the species sampled. Nitrogen was the least variable and Mn and Mo generally the most variable elements for all species. Grand fir had much higher foliar concentrations of K and Ca than the other species. Ponderosa pine had the highest foliar N concentrations. The pines generally have lower nutrient concentrations than the firs, with the exception of Zn. Western hemlock habitat types showed lower Douglas-fir foliar Ca, Mg, and B concentrations, but higher K concentrations than other habitat type series. Douglas-fir growing on soils derived from meta-sedimentary rocks generally had lower foliar nutrient concentrations than those growing on other rock types. West. J. Appl. For. 19(1):13–24.

The natural invasion of mountain alder (Alnuscrispa (Ait.) Pursh) into monoculture plantations of black spruce (Piceamariana (Mill.) B.S.P.) and Sitka spruce (Piceasitchensis (Bong.) Carr.) afforded an opportunity to assess the effects of mountain alder on soils, and on the growth, nutrient status, and survival of spruce in eastern Newfoundland. The plantations were established on ploughed Kalmia–Vaccinium heath in 1968–1969. Significant increases in the growth of spruce were associated with the presence of high densities of mountain alder in the two plantations studied. The increases began 3–6 years after the invasion and establishment of mountain alder. Estimated nitrogen (N) contributions to each plantation from mountain alder leaf litter fall were approximately 50 kg•ha−1•year−1. Spruce foliage N content was 10–15% higher in high-density mountain alder (HD-alder) plots than in low-density mountain alder (LD-alder) plots, but other foliar nutrient concentrations were low and possibly deficient in the HD-alder plots. Development of a litter fall–humus layer was observed in HD-alder plots but not in LD-alder plots; however, B-horizon soil-N values did not differ significantly between HD-alder and LD-alder plots. The mountain alder invasion did not reduce the densities (stems/ha) of spruce. Additional studies on the autecology of Alnus spp. native to Newfoundland, and on alder-spruce interaction are recommended to further the development of an adequate ecological basis for heathland and peatland afforestation in the region.

We tested the hypothesis of nutrient limitation in the trees of the alpine forest – tundra ecotone by comparing the foliar nutrient status of windsculpted elfinwood (also called krummholz) growing at the upper limit of tree success with symmetrically formed toll trees growing at the nearby timberline. The species investigated included Picea engelmannii (Parry) Engelmann, Abies lasiocarpa (Hooker) Nuttall, pinus flexilis james, and Pinus aristata Bailey. The foliar nutrient concentrations of the ecotone trees were similar to other healthy montane forests. Most of the significant differences in mean foliar nutrient concentrations between elfinwood and tall trees indicate lower concentrations in elfinwood trees. We found significantly lower mean phosphorus concentrations in Picea engelmannii and Abies lasiocarpa elfinwood compared with tall trees, but the mean nitrogen–phosphorus ratios were within the normal range. The foliar nutrient status of Pinus aristata elfinwood was similar to tall trees, while Pinus flexilis had considerably more significant differences in nutrient concentrations between the tree forms. Although there are many theoretical processes that could cause nutrient deficiencies at treeline, this study suggests that the elfinwood along the Colorado Front Range is not currently nutrient deficient. We discuss the potential differences in nutrient ecology between elfinwood and tall trees. Keywords: foliar nutrients, alpine ecotone, treeline, elfinwood, krummholz, conifer.

The Relationship

Foliar nutrient concentration differences between provenances, and the relationship between foliar nutrient levels and provenance growth was examined in Douglas fir (Pseudotsugamenziesii (Mirb.) Franco) from the coastal region of British Columbia.In the first experiment differences in foliar nutrient concentrations among four provenances of 3-year old plants, ranged from 8 to 18%. The relationships between these provenances differed according to whether needle, or whole plant nutrient concentrations were considered.In the second experiment 2-year old plants of three provenances, grown under four fertilizer regimes, at each of three nurseries, showed that differences in growth and foliar nutrient concentrations between provenances were affected by nursery. The degree of correlation between shoot length and foliage nutrient concentration varied according to provenance. Coefficients for the regression of shoot length on foliar N and K differed between provenances even when provenance foliar N and K levels were similar. It was suggested that the relationship between foliar nutrient concentrations and shoot length may differ between provenances.

One-year-old seedlings of western red cedar (Thujapiicata Donn ex D.Don) and Douglas-fir (Pseudotsugamenziesii (Mirb.) Franco) were grown for one season in five nutrient treatments with nitrogen (N) supplied in solution at rates of 20, 100, or 250 mg•L−1 and phosphorus (P) supplied at rates of 4, 20, or 60 mg•L−1. Growth, onset of dormancy, frost hardiness on six dates, and foliar nutrient concentrations in autumn and spring were measured. Midwinter rates of net photosynthesis and transpiration were measured at air temperatures of 4, 7, and 11 °C in seedlings from all nutrient treatments. Recovery of net photosynthesis and transpiration in whole seedlings from the three N treatments was assessed at intervals for 28 days after the seedlings were frozen to −5, −15, and −25°C. Foliar N content differed significantly among nutrient treatments and was positively correlated with supply. Mitotic activity ceased earliest in plants with low N supply. Douglas-fir seedlings in the low-N treatment also ceased height growth earliest. These differences in growth had no significant correlation with frost hardiness. No consistent differences in frost hardiness among nutrient treatments were observed. Higher rates of N and P supply resulted in higher rates of winter net photosynthesis. Net photosynthesis was reduced dramatically by night frost, with greater damage occurring at lower temperatures. Net photosynthesis recovery occurred most quickly in seedlings with the midrate of N and P supply.

The distribution of the koala (Phascolarctos cinereus) and the common brushtail possum (Trichosurus vulpecula) within the Prairie-Torrens Creek Alluvials province of the Desert Upland region of north-western Queensland was examined. The optimum habitat for each species as indicated by the occurrence of faecal pellet groups was found to be that associated with creek-lines. However, other land types were also used by each species to varying degrees. The relationship between various habitat variables and pellet group counts was investigated using Multiple regression and a Generalised linear model. Proximity to creek-bed, total basal area of trees, species richness and Acacia basal area (negative) best explained the occurrence of koalas. Proximity to creek-bed, Acacia basal area (negative), total basal area of trees, and available water (negative) best explained the occurrence of brushtail possums. In contrast to studies of arboreal species in the moist-south-eastern forests of Australia no relationship was found between foliar nutrient concentrations and the occurrence of koalas or brushtail possums. However, a significant relationship was found between leaf water concentration and the occurrence of koalas. It is suggested that water availability is the paramount factor defining preferred arboreal habitat in arid and semi-arid woodlands.

Stimulation Of

We evaluated the potential of crushed amphibolite and artificial slow-release N-P-K-Mg fertiliser to stimulate the survival, growth and nutrition of Norway spruce planted on an acidified air-polluted mountain site. Control plots and treatments with slow-release fertiliser (SRF) and amphibolite (AMT) were installed. In the SRF, forty grams of tabletted amendment were applied in the close vicinity of the trees. In the AMT, two kilograms of amendment were incorporated into the soil inside the planting hole of each tree at planting. The SRF application resulted in a significant growth stimulation of spruces. The growth stimulation by amphibolite was perceptible but not significant; this amendment, however, significantly reduced mortality. None of the amendments induced marked changes in foliar nutrient concentrations.
