This is achieved by using variable compost composition, natural sorbents of various types, and encapsulated prolonged-release fertilizers in substrates. popup.description2 The technology of aerobic biocomposting of organic waste was tested both in laboratory and industrial conditions at the composting station of LKP ‘Green City’. It has been shown that microorganisms that promote nitrification improve the structure, porosity and air access to the compost mixture, contributing to additional aeration and nutrient conversion. Microbiological studies have shown that during composting, bacteria of the genus Salmonella were completely destroyed, and the use of microbial preparations, vermicompost and the established composting regime ensures a reduction in the index of Escherichia coli bacteria to the values regulated by DSTU 7369:2013. For the production of encapsulated fertilisers, an experimental installation for encapsulating fertilisers in a fluidised bed was developed. Nitrogen-containing granular fertilisers were encapsulated with coatings based on polyvinyl alcohol and starch. It was shown that the kinetic curves of dissolution of such fertilisers are smooth and predictable. This is evidence of a uniform, high-quality coating, which makes it possible to use long-acting mineral fertilisers with the required release time in technologies for the restoration and rehabilitation of damaged soils. The kinetics of ryegrass development using encapsulated mineral fertilisers were studied, and it was found that such fertilisers have a positive effect on plant growth and development. Based on the combination of different components and stages of damaged soil restoration, the effect of compost-based substrates on plant growth and development was studied. The study was conducted using the bioindication method. It was found that the highest germination rate was in the substrate variant (clay 20%, soil 20%, compost 20%, sand 20%, peat 20%) – 95.8%, and the lowest in the variant (soil 30%, compost 40%, sand 30%) – 85.8%. Most of the proposed substrates are characterised by high average values of the main parameters of ryegrass.
