Assessing Sustainability of Shrimp Aquaculture and Integration with a Field Crop
A field study utilizing a randomized block design has been planned to test the effect of three low-salinity shrimp farm effluent/well water/fertilizer combinations on olive tree growth. Trees will be flood-irrigated as needed. Irrigation water will be analyzed for total nitrogen, nitrate-nitrogen, total phosphorus, potassium and electrical conductivity. Additionally, tree growth as measured both by height and diameter, soil salinity and soil macronutrients (N,P,K) will also be monitored.
- Determine the benefits of irrigating with aquacultural effluents
Determine any detrimental effects on soils
Reduction of reliance on chemical fertilizers
Efficient utilization of scarce water resources
Organize an aquaculture field day to initiate an integrated aquaculture/agriculture extension program in Arizona
Work on the project is underway. The study site has been selected and the treatments have been assigned the rows of trees. Growth studies are slated to begin in the spring of 2002.
