Resumo

The article presents the results of laboratory studies of soils obtained during composting of food and organic waste. The study considered two bulk soil samples collected in May 2024 at a municipal solid waste processing complex in the Moscow region. The main objective is to study the soil properties and the morphology of solid particles after soil composting. The natural soil moisture, solid particle density, and organic matter content were determined in laboratory, and soil particle morphology was studied with a binocular microscope.
