The ISCO 3700 Automatic Sampler Model Number 68-3700-001design for waste water sampling has been used in this study and proved to be a valuable tool for manure sampling in storage for consultants or researchers. Sampling at different depths and locations in the storage facility can be quickly done and processed in order to obtain an accurate measure of the nutrient concentrations. Important differences were obtained from one storage farm to the other therefore, individual sampling should be done for each farm. Sampling in mid-depth generally gave results that were representative of the whole storage.
