ArticleThe preservation of natural forests through the establishment of industrial wood production plantations via the new, fast growing Robinia pseudoacacia ‘Turbo Obelisk’ varieties and new cultivation technologies

No results found.After decades of research and development, Silvanus Forestry Ltd. and HungaroPlant Ltd. have successfully propagated the Robinia pseudoacacia ‘Turbo Obelisk’ variety group and developed the necessary cultivation technologies, specifically for intensive industrial wood production plantations. In comparison to the Hungarian and traditional black locust varieties and cultivation technology, industrial wood production plantations established with our variety group and using our cultivation technologies can produce twice as much timber yield and industrial timber yield, considering 15-year rotation periods. These parameters are comparable with the performance of the widespread Eucalyptus and Pinus plantations in the subtropics. Our varieties and cultivation technologies, however, are also usable in subtropical, temperate, as well as tropical climates. The outstanding yields achieved by the ‘Turbo Obelisk’ varieties and the extremely high industrial wood output can provide a significant contribution to the conservation and maintenance of natural ecosystems, whilst the CO2 sequestration per unit area per time is also several times that of natural forests. A particular advantage to emphasize is long term carbon sequestration due to the high percentage of industrial wood yield. Increasing the exceptional tolerance of black locust against drought, pollution and low-quality soils, our varieties are exceptionally suitable for the utilization of marginal agricultural areas, the agricultural utilization of which would otherwise create an economical loss. This can also significantly increase the advancement of less developed regions. In addition to plantation cultivation, it also provides a cost-effective solution for the establishment of protective forest belts, road-side plantings, quicksand fixation and soil renovation. Delicious honey production is also a possible revenue stream. The global exploitation of the research findings has begun, having already successfully established test plantations in China, India, and Pakistan, as well as in several European countries.

DocumentImprovement of reclaimed soil for sustainable wood energy forest and analysis of growth inhibitory factors by growing season of Populus euramericana
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.In this study, the effect of soil amendment and ferilization on soil physicochemical properties and tree growth(Populus euramericana) in reclaimed land was investigated. The stduy plot were established with two tillage levels and three soil additive levels: control(till 20cm, additives 0kg), T1(20cm, 4kg), T3(40cm, 8kg); each soil amendment treatments can be divided by two fertilization treatment(N: non-ferilized, F: ferilized). The first year after soil amendment treatments, NaCl and EC decreased compared to pre-treatment; however, there were no differences among the four treatments. The organic matter, total nitrogen and available phosphorus measured 3years after treatments, significantly increased compared to control while EC and NaCl notably lowered than control. Especially, EC in all treatments except the control was within the optimum range of tree growth(below 0.4dS/m). In terms of fertilization, chlorophyll concentration(SPAD) and biomass productivity in fertilization treatment were hight than no-fertilized treatment. The PCA analysis was performed to examine the relationship between soil abiotic properties and poplar growth each at the initial stage(rootage) and after rootage. The PCA analysis indicated that the major factor for poplar growth each at the initial stage was soil physical properties which play an important role in the early root development. After root development, soil pH and NaCl in the soil were the major growth inhibitory factors. This findings confirmed that the essential conditions for the efficient production of the wood energy feedstock in the reclaimed land were soil physical properties at the initial stage of (Populus euramericana) (before rootage) but soil chemical properties became important at the lateralstage of (Populus euramericana).
