The research was conducted on the growth and vital functions of watercress under the conditions of encapsulated mineral fertilizers treatment. The cyclic application of mineral fertilizers during three vegetation periods was simulated in this paper. The used mineral fertilizers were encapsulated on the basis of polyethylene terephthalate and polystyrene waste. It was found that the intermediate products of the polymer covering decomposition do not have a negative impact on the soil environment and the use of encapsulated fertilizers is safe for growing plants.

We have carried out research on multi-stage handling of polyethylene terephthalate and polystyrene household waste. The method has been developed for both their safe utilization in manufacturing technologies and the use of encapsulated mineral fertilizers. The technical feasibility of implementing all stages of plastic waste processing has been defined: separate collection, creation of a film-forming composition, encapsulation of granular fertilizers. Our study has confirmed the safe biodegradation of polymer shell residues in the soil environment after the dissolution of the fertilizers. The proposed method of handling of these wastes is a method of their safe utilization.
