Agricultural planets provide food for all other populated planets in your fiefdom. It is important to balance the number of agricultural planets with other kinds, as shortage of food frequently leads to riots, and malnutrition is also one of the black plague preconditions.

Food production depends on the tech level and environmental conditions of the planet. Reforming planets to agricultural is rewarded with NutriCOM shares.

Mining colonies base their income on selling raw ore. The incomes are fairly low, but the colonies only require small working populations and therefore food requirements are low as well. Almost any kind of planet may be reformed to a mining colony, which is also rewarded with a small percentage of Mining Corp shares, however, to reform lunar and gas giant class planets, these shares will have to be traded back.

Mining production depends on the resources of the planet. Gas giants produce three times as much, and lunar planets twice as much.
