The amount of resources preserved by the Fortress level applies to the available resources in the province. If there is only one kind of resource in the province, the whole preserved amount by the fortress will apply for this resource. But if the there is more than it can be preserved, the attacker will loot as much as its army's carrying capacity allows.
