− | [[Dwarves]] require approximately 2 units of [[food]] and | + | [[Dwarves]] require approximately 2 units of [[food]] and 4 units of [[drink]] each season. [[Farming]] can produce enough [[crop]]s to satisfy part or all of these requirements. However, be aware that the more and larger your farms are, the more time and effort must be accorded to their maintenance. |

Brewing always quintuples stack sizes; for example, a stack of [[cave wheat]]s [5] is brewed into a [[barrel]] of [[Dwarven beer]] [25] at a [[still]]. Processing [[quarry bush]] plants into quarry bush leaves at a farmer's workshop also quintuples stack size, as does processing [[sweet pod]]s into [[Dwarven syrup]]. [[mill|Milling]] sweet pods into [[Dwarven sugar]] does ''not'' increase stack size. [[Pig tail]]s and [[plump helmet]]s grow faster than other crops, and as long as the mature plants are harvested promptly, it is not hard to grow multiple crops of either plant each season from the same plot. |

− | + | Each dwarf (age 1 year or greater) consumes 4 [[Main:urist|urist]]s of booze and 2 urists of food per season, or 16 booze and 8 food per year. | |
− | + | A 100 dwarf fortress (not counting infants) therefore needs 1600 booze and 800 food per year. | |

− | + | A single farm tile, with fertilizer, configured for 3 quarry bush seasons + 1 plump helmet season, can produce 150 units of food (quarry bush leaves, 3 seasons * 2 crops per season * 5 plants per crop * 5 leaves per plant) and 75 units of booze (plump helmet wine, 1 season * 3 crops per season * 5 plants per crop * 5 booze per plant). Another tile dedicated solely to booze can produce 300 units (plump helmet wine, as above but 4 seasons), at the expense of variety. Together, they produce 375 booze and 150 food, which is enough for 18.75 dwarves, with some booze left over. That's 9.375 dwarves per farm tile, if the tiles are split in this manner. A 100 dwarf fortress therefore could ''theoretically'' get by with about 11 tiles of farmland, if the dwarves were willing to subsist on a single type of food and booze, and did not need any clothing. | |
− | + | In practice, however, you want booze variety to avoid bad [[thought]]s, and your dwarves are going to need some [[clothing]]. If you grow crops for textiles to make this clothing, that will add more farmland. This calculation also assumes you use fertilizer, which is a dubious practice given the difficulty in maintaining a steady supply of wood. Why use 11 tiles with fertilizer when you could just use 20 tiles with no fertilizer, especially when the latter would use less labor? Finally, the calculation assumes all your planters have Legendary skill, and that there are enough of them to avoid any labor shortages at planting times. This may eventually be true in a long-running fortress, but is not typical in most forts. | |

Given the small number of dwarves, a single smaller farm (2x4 or 3x3) is probably best for beginning fortresses. As the growers [[experience|level up]] and farm yields increase the farm can be expanded and newer, smaller farms with different crops can be added to enable new growers to practice their skills. The more tiles of farm plot you have, the more growers (and harvesters) you will need. |
If you plan to [[farming|fertilize]], farm plots should ideally be one less than a multiple of 4 tiles -- ex. (1x3), (1x7), (3x5), (3x9), (5x7), (7x9) | If you plan to [[farming|fertilize]], farm plots should ideally be one less than a multiple of 4 tiles -- ex. (1x3), (1x7), (3x5), (3x9), (5x7), (7x9) | ||
