Platone Municipality is located on the south of Jelgava town and is a part of the Central Latvian Lowland, which was formed during the Late Weichselian glaciation by the activation of the Zemgale Ice Lobe of the Riga Ice Stream. The diversity of soil cover within the Zemgale Plain south to the Jelgava town was observed. The relatively sharp boundary of the Baltic Ice Lake sand deposits in the north marks off the clayey and silty clayey deposits from the Zemgale Ice-Dammed Plain in the south. Therefore, majority of soils of the research area have been developed from glaciolacustrine deposits with distinct change in soil texture due to the lithic discontinuity. This discontinuity might happen at different depths and effect the water regime. Despite of the congeneric topography – flat or slightly undulating plain –, the heterogeneity of soil parent material and soil cover occurs. Altogether, 55 soil profiles were excavated in the places where soil descriptions were made in 1990. Additional soil profiles were examined during 1997–2017. Data analysis, comparisons between soil classification systems, and the development of Latvia soil classification compatible with the World Reference Base for Soil Resources were the main objectives of the work done in 2022. The project is financed by the Norwegian Financial Mechanism’s pre-defined project “Enhancement of sustainable land soil resource management in agriculture” (E2SOILAGRI).
