In 1985-88, a 25-yr-old Scots pine forest in Netherlands was limed and fertilized with P, K and Mg in a factoral design. This paper addresses effects of these treatments on foliar nutrient concentrations and tree growth. Stem volume increments of individual trees were measured. Average annual volume growth was estimated to be about 16 msuperscript 3/ha, which may be a slight underestimation. P and K showed increased foliar concentrations immediately after treatment and were the only elements that significantly increased volume growth in 1988-91. Additional annual volume growth of individual trees brought about by P and K corresponded with 0.9 and 2.2 msuperscript 3/ha, respectively. Foliar Mg and Ca increased later and insignificantly reduced and increased volume growth, respectively. Lime and Mg applications tended to lower foliar N. When absolute foliar concentrations and element ratios were compared to Dutch and German standards, it appeared that application of some of these standards in present research would not always have given a fully correct prediction of growth responses to nutrient additions.

Scots Pine Forest

In 1985-1988, a 25-yr-old Scots pine forest in Netherlands was limed and fertilized with P, K and Mg in a 24 factorial design and in an experiment with 5 liming levels, in order to alleviate potential nutrient deficiencies as a result of high N depositions (ca. 40 kg ha-1 yr-1). In this paper, effects of fertilization and liming on nutrients in forest floor and mineral soil are discussed as a basis for explanation of foliar nutrient concentrations and tree performance. Of all treatments, liming showed the widest array of effects, especially in forest floor: raised pH and lowered extractable Al in forest floor, and after 4 yr those in 0-50 cm mineral soil. These effects, except for that on forest floor pH, were stronger with increasing lime dosages. Liming showed transient effects on amounts of soil inorganic N (Ni). Until 1989, Ni in forest floor was lowered and that in mineral soil was raised by liming. This could be attributed to the formation of NO3, which is more mobile than NH4. Plots limed with 3 t lime/ha appeared to have higher Ni concentrations in the whole sampled profile than those limed with >3 t/ha or unlimed plots, the reason for which is unclear. Liming removed extractable K and Mg from forest floor probably by exchange against Ca. Residence time of added P and possibly Mg in forest floor was increased by liming, probably by solubility of added fertilizers. Added K was poorly retained in forest floor and probably quickly leached to soil layers deeper than 50 cm.

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.

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.

Alder Leaf Litter

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.
