Forming of environmentally safe ecosystem at recultivation of solid somestic waste landfill (Gatchina town): initial phase of biological stage
Solid domestic waste landfill uses three types of organic substrates for recultivation: sewage sludge (SS), compost produced by local plant for solid domestic waste treatment, and coffee cake as a byproduct of sublimated coffee manufacture. The features of spontaneous overgrowth on each organic substrate have investigated. Characteristics of these substrates determined their use as fertile layer for biological stage of recultivation and created the necessary prerequisites for forming of environmentally safe quasi-natural ecosystem. All investigated substrates are differing in active trophic riches, floristic compositions, vegetative cover and overground plant biomass. The seedlings of trees and shrubs appear in vegetation cover in the pioneering phase of its forming. These species are representatives of both native and cultivated flora.
