Fur

Explanation:

The Middle Colonies consisted of what is now Pennsylvania, Delaware, New York, and New Jersey. These colonies had very fertile soil that enabled them to farm effectively. They farmed mostly grain crops like wheat.

Another thing they did was hunt. With the presence of many animals in the forests as well as American Indians that traded in fur, the Middle colonies were able to export fur to other colonies and to Britain.
