Considerable quantities of dirty water, composed of milking parlour wash-water, milk spillages, runoff from cattle yard areas and, possibly, effluent from silage and manure, are produced on dairy farms In Ireland, dirty water from dairy farm facilities is normally managed by spreading on, or irrigation to, land It has considerable potential to cause water pollution due to its high pH, 5-day biochemical oxygen demand and its N and P concentrations The objective of the present study was to contribute to better management of dirty water on dairy farms by providing estimates of its composition using rapid methods that can be easily used on farms During the experiment, 34 samples were collected from the facilities on the dairy farm at Teagasc, Johnstown Castle (Wexford), between 27 January and I May, 2006 Dry matter and specific gravity provided the best indicator of biochemical oxygen demand, total nitrogen and phosphorous, and micro and macro nutrients The nutrient concentration of dirty water can be determined rapidly using either dry matter concentration or specific gravity, enabling farmers to Include this information in the nutrient management plan for their farm
