As a result of military operations on the territory of Ukraine, sown areas are reduced,
the cost of plant protection products and fertilizers increases which emphasizes the problem of
obtaining maximum yields from a smaller area of farmland. Given that a shortage of food grains
can cause a global food crisis, research on the use of MSW as an environmentally friendly
substitute for agrochemicals is relevant today. The aim of the research was to assess the
ecotoxicological properties of MSW as an environmentally friendly substitute for synthetic
agrochemicals. The impact of MSW as a fertilizer on soil chemical properties and assessment of
MSW phytotoxicity as an herbicide for weeds and productivity of winter wheat were studied
under field conditions. Toxicological assessment of MSW under laboratory conditions was
carried out according to the following parameters: acute oral toxicity and resorptive-toxic effect
of MSW. As a result of the assessment of MSW impact on soil chemical properties, it was found
that significant soil acidification occurs only when MSW dose of more than 2,400 L ha-1 is used.
The content of nitrates and oil products did not increase and there was no soil salinity when the
MSW was used in doses of 300–1,200 L ha-1
. It was determined that the greatest decrease in weed
plant biomass (85.5%) was observed when 100% concentration of MSW was used in a dose of
350 L ha-1
. As a consequence, with reduced weed infestation, there was a 21.5% increase in
winter wheat yield if 100% MSW was used and a 19.1% increase if 75% MSW was used. As a
result of the toxicological assessment of MSW, it was found that it belongs to low-toxic
compounds. These results of ecotoxicological investigation of MSW make it possible to assert
that its use is safe in agriculture, in particular as an environmentally safe organomineral fertilizer
and herbicide.
