Phosphorus Retention and Storage by Isolated and Constructed Wetlands in the Lake Okeechobee Basin
Contract No:  62071
Goals and Objectives
 
Small historically isolated wetlands, which are a common feature throughout the Okeechobee Basin cover about 12,000 ha of the four priority sub-basins. These systems (about 50%) are presently ditched and drained. Hydrologic restoration of these wetlands may help to provide water storage and long-term phosphorus (P) retention within OkeechobeeĆ¢?Ts four priority basins. In addition, constructed wetlands strategically placed in the watershed can also aid in increasing P retention. Objectives: 1. quantify P storage in historically isolated wetland soils at the landscape-scale 2. determine soil characteristics and processes responsible for effective P storage in historically isolated wetland soils 3. determine efficacy of hydrological restored isolated wetlands to store and retain P from cow-calf operations, and to determine subsurface phosphorus transport 4. measure P assimilation rates and equilibrium P concentrations of wetland soils 5. determine the effect of fluctuations in hydrology on P flux 6. optimize on farm constructed wetlands to increase P removal performance using pilot scale studies 7. review current hydrologic and P models for adaptation to the Okeechobee Drainage Basin and use these models to simulate P retention capacity 8. communicate the findings and experiences gained during this project to dairy farmers and beef cattle ranchers through extension media
