How big is the pond?

What is the water source?

How much water comes into the pond on a monthly basis?

It would also be useful to know what the turnover is for the pond. In other words, how long does a drop of water stay in the pond.

Do you aerate?

The bottom line is that you are trying to determine how long the nitrogenous waste products from the fish remain in the system. If it's a short period of time, you can feed significantly more than if the water has time to build up these wastes.

As a general rule, if wastes are allowed to build up in your pond, you will get more plant growth in the form of rooted vegetation, and algae. The more plants you have, the more destructive they are to your fishery when they die.
