Abstract:
Residues of building material play an important role in construction material recycling and circular economy. The present thesis deals with the evaluation of the substrate RMH as a material for soil bioengineering reinforcement constructions to stabilize soil erosion and slopes. Furthermore, this analysis/thesis aims at examining the substrates’ effects on biomass and the vitality of woody plants. Two test facilities were set up with two different substrates in Groß-Enzersdorf, Lower Austria. Live stakes from Salix purpurea and rooted plant inlays from Acer campestre were installed as hedge brush layers. Vitality and growth parameters, such as appearance, leaf health, leaf sizes, number of leaves, and cubic plant quantities were taken from the entire test facility. The dry weight of the biomass was extracted/measured from the first running metre. The Acer campestre plants sprouted strongly. The vegetation’s vitality on both experimental plots appeared weakened due to poor leaf health and a lower number on leaves. The factors emergence of weeds, nutrient deficiency, and leaf diseases affected the vitality of the plants. Statistical analysis showed that the production of aboveground and belowground biomass is not significantly different in both plots. In the substrate RMH, the amount and weight of adventitious coarse and fine root of purple willow cuttings was twice as much as in the reference substrate VG. Consequently, the soil of substrate RMH was rooted faster and deeper than in the reference substrate. This has a positive effect on the stabilization of the soil or slope against erosion.
