Reference soil Netherlands 6: Fluvisol

A deep, clayey soil with low chroma (/1), derived from holocene alluvial deposits, with a weak prismatic structure breaking into moderate subangular blocks. There are shallow drainage channels on site, the groundwater table is below 120 cm. In B1 horizon, there are some brick pieces. At 105 cm, there is the top part of a buried soil.
