Agriculture

-Every 50 acres of farmland requires 1 worker (10 gp/day). A plow animal adds 50 acres to what a farm worker can cover, such that 100 acres only requires 1 worker and 1 plow animal (plow animals are horses, donkeys, and cows).
-If the farmland is irrigated, double its yield.
-Starting 100 acres of farmland requires 50 gp of equipment (5 sp/acre).

1 ration = 5 sp of human food

Crops (yield per acre per year):

-Alfalfa - 6,000 sp feed
-Potatoes/Carrots/Cabbage/Leeks - 250 rations
-Corn - 200 rations and 1,000 sp feed
-Wheat - 1,500 sp feed; if you have access to a powered grindstone and a millworker (10 gp/day) per 1000 acres of wheat then convert feed to an equivalent value of rations (300 rations/acre)
-Apples/Pears - 320 rations - takes 10 years to start producing fruit

Animals:

-Riding horse - 150 gp, 5 sp feed/day, 1.15x annual growth
-Warhorse - 400 gp, 6 sp feed/day, 1.1x annual growth
-Riding pony - 125 gp, 4 sp feed/day, 1.15x annual growth
-War pony - 300 gp, 5 sp feed/day, 1.1x annual growth
-Donkey/Mule - 100 gp, 5 sp feed/day, 1.15x annual growth
-Guard dog - 80 gp, 1 ration/day, 1.4x annual growth
-Chicken - 15 gp, 1 cp feed/day, produces 1/30 rations/day or 1 ration of meat, 3x annual growth
-Goat - 40 gp, 1 sp feed/day, produces 1/2 ration/day or 15 rations of meat, 1.3x annual growth
-Sheep - 40 gp, 1 sp feed/day, produces 2 sp wool/day or 15 rations of meat, 1.3x annual growth
-Cow - 150 gp, 8 sp feed/day, produces 6 rations/day or 200 rations of meat, 1.2x annual growth
-Pig - 40 gp, 2 sp feed/day or 1 excess ration, produces 80 rations of meat, 1.5x annual growth, boars can be trained for war (at most half of your pigs can be boars) - 1 beast trainer per 5 boars

Converting eggs into rations requires an oven and a cook (10 gp/day) per 100 rations/day created this way. Excess eggs go bad and are lost.

Milking goats and cows requires one milkmaid (10 gp/day) per 100 rations/day created this way. Excess milk goes bad and is lost.

Cheese production - If you have access to an oven, a cheesemaker (10 gp/day), and a seed culture, then you can convert milk into cheese. After 60 days, all milk production becomes cheese production. Your cows and goats produce double rations. Excess cheese is not lost.
