Multivariate Analysis of Paired Watershed Data to Evaluate Agricultural Best Management Practice Effects on Stream Water Phosphorus.

Studies the reductions in phosphorus loading attributable to an extensive program of agricultural best management practices (BMP) implemented on a working dairy farm in the watershed of a water supply reservoir in New York City. Quantification of the BMP treatment effects; Use of statistical formulas to estimate the analytucal power and minimum detectable treatment effect associated with the paired watershed analysis; Event flow volumes at the farm watershed.
