dc.description.abstractAs 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.eng
