No Seed without Additives!
The most common fault when setting restoration measures on raw soils is to apply seed without necessary additives. Even donor areas of extremely poor and dry grassland are functioning ecosystems and a corresponding nutrient cycle. Hence, generally an initial nutrient admixture and soil amelioration is required in vegetation areas with raw soils, so that a dynamic ecosystem with functions corresponding to bioengineering can develop. However, by using autochthonous seeds of optimally adapted plants, the amount of additives can be reduced in most cases.
Establishing native vegetation usually aims at semi-dry or dry grassland rich in species with a root system ensuring reliable erosion control.
With indigenous vegetation, sown with the hay-mulch and Heudrusch® - procedure, a larger acceptability of civil engineering construction measures and landscape interferences is achieved, as an increasingly sensitized public observes and appreciates the aesthetical, ecological and economical aspects arising by the biodiversity and floweriness and the considerably reduced maintenance costs. To ensure quality assurance, we recommend the cooperation with renowned organizations. Meanwhile, long-term experience with autochthonous vegetation forms the basis of the described procedures.
Under the name "Regiosaat", the associate partners BENDER and JULIWA-HESA offer autochthonous seed with regionally harvested hay-mulch. The Heudrusch®-method is carried out in cooperation with our partner engelhardt.oekologie.
