Through normal daily operations, the project will generate a large quantity of high-nutrient-level organic matter, i. e., vegetable trimmings, ash, leaves, grass clippings, and fish offal not suitable for feed. This material will be composted in specially designed containers that conserve nutrients. It will then be tested and adjusted for nutrient balance and ph, and used in separate greenhouses for the production of root crops. Fish tank effluent will be used to irrigate these crops as well. Since the effluent will not return to the tanks in this type of system, it will be replaced with fresh water. However, the plant growth stimulating effect of the fish effluent will still be in force, resulting in vigorous growth of the plants.
