Some lagoons are in pretty good condition and need just a maintenance dose of <a title="Activated EM•1®" href="http://www.teraganix.com/Activated_EM_s/261.htm">Activated EM•1<sup>®</sup></a>. Others may need a more aggressive treatment plan.  These application rates can be used for manure pits, as often found in hog barns, as well.

If the lagoon has a crust and/or a large volume of sludge, continue application until some level of clarity is seen. It would be wise to measure sludge levels to set a point of comfort level as to when to decrease application rates to a maintenance dose.
