Effects of Surface Application of Dairy Manure on the Infiltration Rate and Quality of Surface Runoff

摘要

The purpose of the research project for which results are presented in this report was to measure and to evaluate quantitatively the pollutants' concentration in runoff generated by a simulated rainfall event as affected by the form of the dairy manure applied, the nitrogen loading rate and the time delay between manure application and the rainfall event. The plots are on an established pasture planted with fescue grass. Also, presented in this report is an objective developed during the research phase which was to assess the saturated or steady state infiltration rate of the manured plots during a simulated rainfall event as affected by the same parameters cited above.
