Advanced Harvesting Program is a technology that can be researched at the Food Proc Ctr in Tech Level 4. It costs 250 Food and 250 Carbon, and makes Farms produce +175 Food. Harvesting Program must be researched before it becomes available.
Unless the player has enough animals in the Animal Nursery to ensure a good flow of food, this technology should be researched soon after reaching Tech Level 4, so that less carbon is spent replanting farms. If there are enough animals, the player should research Cloning instead.
"This Tech Level 4 farming technology makes Farms even richer, so that they rarely need to be replanted."
