The paper presents the analysis of retention properties of mineral soils, and an attempt to establish statistical relationships of the soil basic physical properties and characteristic moisture contents. Because of a relatively complicated and time-consuming process of a direct measurement of moisture and retention soil characteristics (e.g. pF curves), more often indirect methods are sought, such that utilize relationships between basic physical properties of the soil, and characteristic moisture contents. In this paper, the relationships between individual soil texture classes, soil density and the content of organic matter with water retention at certain soil suction values (pF values) were analysed. The research was performed on 59 mineral soils of a diverse textural composition, from sands to heavy clays. The relationship between examined properties and the soil moisture at certain pF value was proved statistically.
