Growth and Biomass Production of Six Coniferous Species on Luvisol     pdf     HR     EN 361
Summary: An investigation was carried out in the area of the Bjelovar Forest Administration, at the pilot plots "Slatki potok", in a comparative experiment with six coniferous species. The pilot plots are located in the hilly area of the Bjelovar Basin. Geographical positioning was: 45 degrees and 46 minutes ofnothern latitude, 17 degrees and 3 minutes of eastern longitude and 140- 145 m altitude.

The climate of the investigated area is humid, and the soil is luvic to to sloghl pseudogleic. With regard to vegetation it is an area of Sessile/lowered Oak and Common Hornbeam forest.

In the comparative experiment the growth of the following coniferous species was investigated: Norway Spruce (OS), Scotch Pine (OB), Austrian Pine (CB), European Larch, (EA), Douglas-fir (ZD) and Eastern White Pine (AB).

The planting material utilized was of known origin. The field experiment was established in the spring of 1969. A randomized block design was applied in three repetitions. Spacing of planting was 2x2 m (2.500 N/ha) in all species.

The latest measuring during the experiment was taken in the autumn of 1994 and spring 1995, i. e. in the 26th year following its establishment. Plant survival was registered and the height and diameter breast height of all trees was measured. The volume of wood was calculated by measured. The volume of wood was calculated by means of one-entry tables-tariffs. The mean stand tree of each species was calculated by means of the mean basal area and height curve. The produced biomass in each area unit was calculated by means of the mean stand tree, which was felled at each repetition. The weight of the fresh matter of the stem, stump, roots and branches was determined by weighing. Samples for laboratory analyses were taken from all parts of the tree. The samples were dried at 105 degrees C up to a constant weight, cut into small pieces, and analysed. A high percentage of survival was registered in Scotch Pine (81.8), Austrian Pine (80.1) and Norway Spruce (79.9), and considerably poorer in European Larch (39.1) and Douglas-fir (17.4). With regard to the diameter and height growth the leading species were the Douglas-fir (18.9 cm and 18.71 m), Eastern White Pine (21.5 cm and 19.15 m) and European Larch (18.9 cm and 18.7 m). The indigenous species of Scotch Pine, Austrian Pine and Norway Spruce demonstrated slower growth in this developmental phase. In view of the volume of wood produced per hectare the leading species are the Eastern White Pine (549.12 m3) and Scotch Pine (336.72 m3), while, due to the low survival percentage, the European Larch (250.00 m3) and Douglas-fir (169.08 m3) are considerably poorer.

Similary as in the case of growing stock, Eastern White Pine produced the largest (242.324 kg/ha), and Douglas-fir the smallest (127.616 kg/ha) amount of dry plant matter. With regard to the production of biomass the Eastern White Pine is followed by the Scotch Pine (218.081 kg/ha) and then, considerably lagging behind, follow three species; Norway Spruce (175.921 kg/ha), Austrian Pine (168.228 kg/ha) and European Larch (158.231 kg/ha). The share of bolewood biomass in the overall biomass was relatively the smallest in Norway Spruce (55.92), and the greatest in European Larch (71.3 ). The biomass share of the subsoil part ranged between 10.1 (Austrian Pine) and 16.2 (Eastern White Pine). Regarding nutrients, wood was the poorest, while needles and bark were the richest. In the majority of the tree species investigated the biomass contained the most nitrogen, followed by calcium. The spruce in this experiment, as in several other experiments, absorbed the most calcium. With regard to the effectiveness of the absorbed nutrients, particularly nitrogen, in view of the bolewood dry matter produced, it was highest in European Larch, and lowest in Norway Spruce,
