| Summary: | The paper presents the impact of UGmax enricher on soil physical and water retention properties. The experiment was established in 2005 in a 2 ha field 9 km from Lidzbark Warmiński in the village of Budniki. The studied soils were classified as Cambisols and Luvisols (IUSS Working Group WRB 2015), and they were formed from glaciolimnic deposits. Soil bulk density, soil particle density, texture, total porosity and water retention properties using low and high-pressure chambers were determined. The use of UGmax enricher on loamy soils used as arable lands in temperate climate of north-eastern Poland caused significant decrease of soil bulk density, increase of available water capacity and readily available water capacity. Statistically significant differences between examined soil properties were observed in most studied years.
