Bone Meal

Bone meal is a material used in Dye-making. It can be made by placing a bone into a crafting square. It only requires one square, so can be made without the workbench.

Uses

 * Bone meal is used to make white wool by crafting one Wool block with bone meal above it.
 * Bone meal can be used on crops and saplings to fertilize them (although the tree may not grow properly (in multiplayer), as shown in this video), instantly making them ready for harvest. This makes the process of farming much faster.

Crafting
Bone meal can be used to make a number of dyes such as white, for wool.

Trivia

 * If you use bone meal and the crop does not grow, the bone meal still is consumed.
