Agriculture

Agriculture is a mod by the Metallurgy Team. It is used to expand the cooking and farming systems within Minecraft. It adds new machines, recipes, and a new hunger system called the Well Fed system.

Well Fed System
Eating a "good" food item (processed) will give you Well Fed points. You can view the points on your hunger bar as a golden outline that very slowly degrades. There are 20 levels of Well Fed, each one will improve your movement and item-swinging speed by about 1%.

Crops
The Agriculture mod adds a variety of Crops and Spices to the world. Spices are rare plants that drop bits of their type as you hit them (but lowers their growth stage each hit) when they are at stage 1 they can be broken and replanted on tilled ground. There are no seeds for these. Cinnamon is the main Spice available with Agriculture. There are also Peanuts and Strawberries, which you can find in treasure chests scattered around the world (dungeons, strongholds, villages, etc.).
