Farm (Age of Empires II)

Farms in Age of Empires II provide a steady Food source inside a player's base. They may be upgraded to provide more Food at the Mill by the technologies Horse Collar, Heavy Plow, and Crop Rotation. Farms may be built early on, but become most useful in the late game, where they provide high amounts of Food due to upgrades and also because most other food sources (animals, forage bushes) are eventually used up.

Unlike in Age of Empires I, Farms may only be gathered from by one Villager at a time. Farms are very weak and do not hinder movements of friendly or enemy troops. If an enemy takes over a farm, he may use a Villager to collect from it. Farms can be automatically reseeded by "buying" them in advance from the Mill.

Overview
''The technology of farming was carried forward into the Middle Ages and improved. Northern European soils were often rich glacial deposits hidden under dense forests. Over the course of the Middle Ages, much of this land was cleared and converted into farms. Key technology improvements in farming were the improved horse harness, the heavy plow, and crop rotation. The new horse harness did not choke the animal and increased pulling power. The heavy plow could cut into the dense soils. Farms in Europe were largely communal affairs where each family received the produce of several rows in the field. The production of some rows went directly to the local lord as his rent.''
