Abstract: Organic soils that had been drained in order to obtain fertile agricultural land underwent changes leading to the formation of mursh (also known as moorsh). The mursh-forming process is a generic soil process that occurs in drained (artificially or naturally) organic soils, and leads to the changes in soil morphology, soil physical properties (including water retention capability), physicochemical properties, and chemical and biological properties. The aim of the paper is to present scientific knowledge on mursh soils, especially those that are not available to the wider audience. We firstly reviewed scientific literature on the mursh (moorsh) forming process of drained organic soils used for agriculture. We described the specific character of organic soils, differences between mursh and peat, the origin of the mursh-forming process, and the classification of organic soils (Histosols). Additionally, we described the changes in organic matter, such as the loss of soil carbon, increase of availability of plant nutrients, and leaching of biogens to groundwater. We revealed that the mineral matter in organic soils can be an indicator for distinguishing various types of murshes. We have highlighted the current gaps in the research that need to be filled in. The mursh-forming process is inherently related to the mineralization of soil organic matter and leads to a reduction of organic carbon in soil. Mursh has many unfavorable properties with regards to agriculture and environmental management. These properties are mainly related to decreased water storage capacity, which significantly limits the hydrological function of organic soils. The use of drained organic soils is a trade-off between environmental quality and agricultural production.
