Without detailed knowledge of site properties, there is the risk, that measures for establishing vegetation and slope reinforcement remain without success, and thus, do not fulfil their functions. Unfortunately, it can be observed, that seed comparatively often does not come up, or if it comes up, does not grow properly. Then, there are slope areas, which - in spite of applied soil bioengineering techniques of slope reinforcement - have slipped off or show erosion grooves.
Frequently, insufficient knowledge of the site properties is the reason. This leads to the application of unsuitable or wrongly dosed components like seed, fertilizers and soil conditioners or inadequate reinforcement constructions not suited for the respective site.
A detailed knowledge of the site properties of the area to be reclaimed, revegetated or reinforced, decisively contributes to avoid imperfectly sowed vegetation and slope reinforcements.
A survey of the most important site properties:
Most soils and substrates usually require no detailed analyses in the laboratory, as the relevant parameters generally can be sufficiently determined or approximately evaluated by an inspection, a sample of the soil and a glance at the geological map.
Due to our decades-long activities and comprehensive project experience we are perfectly acquainted with sites in all natural and cultural areas from the coast to the Alps, from the Rhine to the Oder and far beyond those, even with sites in other climates.
Merely extreme sites especially hostile to plants, like e.g. tertiary sands of lignite opencast mining, hard coal mining waste, technogenic soils, polluted areas and often road sides (salt), frequently deserve a close soil-chemical analysis.
Particular important is a professional on-site soil preparation, e. g. according to the German DIN 18915. Soil compaction and planished slopes should be avoided as this would result in germination and growth depressions!
