Technical Description
Substrate Engineering Before Seeding
Soil amendment is targeted modification of specific substrate parameters that prevent vegetation establishment — not standard fertiliser application.
Physical amendment: Perlite, expanded clay, mineral aggregates, organic fibre fractions. Target: water retention, aeration, root penetration. Zeolite for cation exchange capacity improvement.
Chemical amendment: pH correction, salt reduction, neutralisation of phytotoxic compounds. Lime-based and gypsum-based protocols selected based on substrate analysis.
Biological activation: Introduction of microbial communities and mycorrhizal associations appropriate to the target vegetation and substrate conditions.
Assessment Parameters
Key Amendment Parameters Assessed Before Specification
01
Substrate texture and pore structure — compaction level, clay/silt/sand fraction, hydraulic conductivity
02
pH range and buffering capacity — acid mine drainage assessment, lime requirement calculation
03
Electrical conductivity and salt load — sodium adsorption ratio, gypsum requirement for sodic soils
04
Heavy metal profile and phytotoxicity — species tolerance thresholds, immobilisation requirements
05
Organic carbon content and C:N ratio — humus layer development potential, nitrogen availability
06
Microbial activity baseline — soil biology status, mycorrhizal inoculation requirement
07
Water retention and field capacity — amendment volume calculation, polymer requirement
08
Target species establishment tolerance thresholds — species selection informed by substrate analysis
Formulation Development
Biopolymer Solutions GmbH — Amendment System Formulations
BPS develops amendment formulations — water retention polymers, biopolymer binders, mineral conditioners — that integrate into the substrate amendment system as functional engineering components.
For contaminated and inert substrates, BPS develops pedogenesis systems for the Desert-to-Green initiative: engineered conversion of inert substrate into a medium capable of supporting self-sustaining plant communities.
R&D: Biopolymer Solutions GmbH, Austria
Project Inquiry
Substrate amendment specification requires site-specific analysis. SRBT assesses substrate parameters and engineers the amendment system as the foundation of the vegetation concept — not as a separate preliminary measure.
