Ducklings are raised in the rice fields to do the weeding, fertilizing, and pest control, instead of farmers relying on pesticides and the usual deep water method for weed control. There are only upsides to this method, as labor and pesticide costs for controlling weeds and insects are minimized and the soil health is improved. By raising ducks in the field along with the rice, LFF is able to do its part in helping the environment while producing two sources of food in the same field with less resources used.
