| Abstract: | Public-private partnership efforts are working towards creating green landscapes from abandoned industrial sites. Fabricated soils, potentially an essential element of such landscapes, are designed to substitute for top-soil on the areas free from ground cover and plant community. The aluminosilicate matrix and humus form the soil micelle – the primary unit of any soil complex. Humus formation is a process based on carbon–nitrogen interaction. Sources of carbon can be materials rich in easily composted products like cellulose and polyphenols (plant leaves) or aged lignin polymers (saw dust from different woody plants). The pathways of carbon–nitrogen complexes are discussed. Properties of the fabricated soil components were examined by bio-tests and plant models. |
