Description:
Feasibility and market potential were determined for non-food-chain crops cultivated using sewage sludge. Non-food-chain crops that are currently being sold on the open market or that have a good potential for marketability were selected. From a list of 20 crops, 3 were selected and subjected to a cost analysis to determine how the costs for cultivation using sewage sludge compared with the costs for cultivation using commercial fertilizer. Cotton, sod, and energy biomass trees were determined to have the best potential for cultivation using sewage sludge, based on the market values and nutrient requirements for each crop, and on the hectares presently under cultivation for production of these crops. Results indicate that large quantities of sewage sludge can be used, based solely on the nitrogen and phosphorus requirements for the cultivation of these crops.
