Slurry agitation can be problematic on many farms around the country due to awkward tank design or very dry slurry. Some farmers spend hours agitating very thick slurry. Adding water from time to time would help in a lot of cases. But in some situations farmers find that even with additional water agitating can be difficult. Slurry additives, more commonly known as slurry bugs, are not a new phenomenon on Irish farms, but have been receiving more attention recently.
