[[File:soil_preview.png|thumb|270px|right|Probably not enough for 80 dwarves.]]'''Soil''' is the name for the various kinds of ground that can be [[farming|planted]] on (both above and below ground) without [[irrigation]] using [[water]].  In ''Dwarf Fortress'', the category of "Soil" includes all types of sand, [[clay]], ooze and any "non-stone" layer equally, even if you or I generally don't associate that substance with "growing plants".

'''Notes:'''
* The "topsoil" types listed in the upper part of the table do '''not''' count as [[sand]] for [[glass]]making, even if their names include the word "sand" - only those in the "Sand" section are usable for this purpose.
* The 3 "ocean floor" layers are only found under deep [[ocean]] tiles, usually far out from any embarkable site. Thus, they can rarely, if ever be encountered, in either [[fortress mode]] or [[adventurer mode]].
* Soil layers marked with {{Raw Tile|≈|1:1:1}} are capable of supporting an [[aquifer]].
* The [[clay]] types listed at the bottom can be used for making ceramic items. Fire clay produces [[stoneware]], while the other types produce [[earthenware]].

In previous versions, types and quantities of available soils were listed at the bottom right of the fortress location selection screen; in the current version, however, it will only indicate the presence of soil and whether it can be used as [[clay]].

Digging into soil does not generate any byproduct materials, unlike digging in [[stone|rock]], and also is a much faster process which makes it much easier to create storerooms and other large areas of empty space, and to train [[miner]]s.

Soil cannot be [[Smoothing|smooth]]ed, which makes it more difficult to make high-value rooms or pierce [[aquifer]]s, and impossible to carve [[fortification]]s, [[track]]s, or [[engraving]]s.

Building a [[farm plot]] or [[road]] or removing a [[construction]] on top of soil will cause it to become "furrowed", making it appear with the {{Tile|≈|6:0}} and {{Tile|~|6:0}} tiles. Furrowed soil — including furrowed subterranean soil — will gradually smooth itself out, at which point grass and other vegetation will begin to grow. Sand always appears as {{Tile|≈|6:0}} and {{Tile|~|6:0}} and cannot become furrowed - as such, sand roads do not last as long as those made on ordinary soil.

===Trees and Shrubs===
Once you discover the [[cavern]]s, subterranean trees, shrubs and mosses will begin to grow on any subterranean soil.  Any kind of vegetation implicitly has some soil under it, even if it grew on [[mud]]dy stone; clearing the growth (such as by building a [[road]]) will thus create a soil floor, even in a stone [[layer]].  It will typically correspond to the lowest soil layer in the local [[biome]]; if that happens to be useful clay or sand, an enterprising player can use [[irrigation]] and some patience to move their sand/clay collection [[zones]] closer to the [[magma]].

== Kaleidoscopic soil ==
If the game somehow fails to assign any soil materials to the current region's geological layer definitions (e.g. if the {{token|SOIL|imat}} or {{token|SOIL_SAND|imat}} tokens are removed), then when the game attempts to determine the material used by a given soil tile, it will return a '''random number''' in order to alert the user that something has gone wrong. As a result, the tile's appearance will rapidly change, and [[mining]] will yield a random [[stone]], [[gem]], or unusable boulder made of [[metal]] or other [[material|generated material]] and leave behind a floor composed of the original layer material, assuming the mining job does not randomly cancel due to the selection of an undiggable material such as [[slade]].

The same thing can happen with layer stone tiles if no materials are marked with an appropriate layer type (such as {{token|IGNEOUS_EXTRUSIVE|imat}} or {{token|SEDIMENTARY|imat}}).
