Multivariate analysis of covariance to determine effects of near-stream best management practices on nitrogen and phosphorus concentrations on a dairy farm in New York

A study in the Catskills Mountains of New York State found that near-stream best management practices, specifically exclusionary fencing and cattle crossings, reduced soluble reactive phosphorus (SRP) concentrations in a treatment creek by 27% annually (34% during the growing season), though they had little effect on nitrate nitrogen concentrations.

• The implementation of near-stream best management practices (BMPs), specifically exclusionary fencing with a cattle crossing, resulted in a 27% yearly reduction in soluble reactive phosphorus (SRP) concentrations in the treatment creek, with the reduction increasing to 34% during the growing season. However, these practices had little impact on nitrate nitrogen concentrations.
• The performance of the multivariate statistical model was significantly improved by incorporating SRP concentrations from a nearby control creek and controlling for groundwater hydrology (water table height) and groundwater SRP levels.
• The study concludes that protecting near-stream areas from practices that cause pollution is an important method for controlling phosphorus levels in water bodies.
