The soils at Polonnaruwa area belong to the general classification of alluvial soils. The Alluvial soils vary considerably in their fertility characters. These soils are formed on recent water laid deposits in which there is no profile development other than accumulation of some organic matter on the surface. Considerable variation is observed in the texture, depth, drainage and colors of the alluvial soils. Because of the extremely wide range of characteristics exhibited, it is not possible to describe a model profile in respect of these soils. Rice could be grown very successfully.
