The aim of this study is to investigate the degree to which pseudogley structure is changed by vegetable production in plastic-covered greenhouses, under the conditions of intensive irrigation and fertilization. The six-year-long implementation of drip irrigation system caused some changes in the soil structural composition in the sense of a mild increase in the content of larger-sized aggregates (greater than 5 mm), but also their greater liability to decomposition, as well as a mild decrease in the percentage of water-stable aggregates larger than 1mm. The soil waterlogging in the plastic greenhouse led to elevated processes of structure deterioration, the formation of crumby aggregates, as well as to the decrease in water stability of structural aggregates.
