Quantifying the Effects of Phosphorus Control Best Management Practices. In: Radcliffe, D.E., Cabrera, M. L., editors. Modeling Phosphorus in the Environment. Boca Raton, FL: CRC Press. P. 351-382. Interpretive Summary: An interpretive summary is not required. Technical Abstract: Techniques for quantifying Best Management Practice (BMP) effectiveness have expanded from individual BMPs on experimental hill slope plots to modeling and model-based approaches and, more recently, to watershed-level optimizations of BMP solutions. This chapter explores this progression and points out assets and roles of each technique. Additionally, this chapter discusses a number of issues to be kept in mind when modeling BMPs and interpreting the resulting impacts to the natural system. Recent work in multi-objective optimization holds exciting promise for further evaluating phosphorus control BMPs, in line with potential secondary effects on other pollutants such as nitrogen, and will increase the overall effectiveness with which we can protect our natural resources. Three examples of quantifying BMP effectiveness are provided. These examples demonstrate work at the watershed, farm, and field levels. Continuing and expanding on such work will provide the interdisciplinary methodologies we need to locate BMP suites that are not only effective in reducing pollutant losses, but that are also cost-effective at the public and private level and socially acceptable to the local community. |
