Pit-King slurry store


Pit-King® is a manure digestant product designed for farm manure pits, lagoons, slurry stores, feedlots and pens. It contains a patented and proprietary blend of enzymes and microorganisms that help break down manure solids produced by dairy cattle, beef cattle and swine.

Key Ingredients

  • Multi-enzyme Blend: Rapid breakdown of manure solids and undigested substances (i.e. fibers, starches)
  • Enzyme-producing Microorganisms: Continued decomposition of manure solids in pits, lagoons and slurry stores
  • Viable Microorganisms: Increase manure solid decomposition and reduce commonly associated obnoxious odors (i.e. ammonia, methane, hydrogen sulfide)

What Clients Are Saying About Pit-King

  • “...had results in the first week of application. The manure smelled different and was very easy to pump.” — East Wisconsin farm
  • First time in 17 years we have not had a lot of solids floating in lagoon.” — North Indiana farm
  • “After just two weeks and during cooler temperatures, the Pit-King treated manure pits took three hours less time to ‘stirate’ compared to the untreated pits.” — South Wisconsin farm
  • The manure pumps easier, faster and with less agitation. Now we get 14 days of manure in the holding pit instead of 12 days. The solids that stayed in the holding pit are now gone, giving us more capacity.” — Central Minnesota farm
  • “We have two pits, one treated with Pit-King and one not, that we pumped simultaneously after three weeks. With an older pump and six-inch hose, the manure treated with Pit-King pumped faster than the untreated manure, which was on a newer pump and eight-inch hose. The Pit-King manure had much less odor, too.” — Northeast Iowa farm

What Users are Seeing

At a large Washington dairy farm, Pit-King was added to the lagoon in late May. Within one month, the farm noticed considerably fewer floating manure solids. The lagoon also became much easier to manage and odor levels saw a steady decrease during that time period.


How Much Pit-King Do I Need?

The amount of Pit-King applied and frequency of application will be dependent on the amount of waste entering the pit. Adjust the treatment amount and frequency with consideration to historical build‐up of solids and amount of waste entering the pit. For example, if hay or bedding, disinfectants, detergents or excessively hard water is entering the pit, then treat heavier with Pit‐King. We would suggest at a 1.5x rate.

For pits with more than three feet of manure solids, then triple (3x) the initial “shock” treatment and double (2x) the treatment amount for the next two months of treatment as well in order to enhance solids reduction in this type of scenario.
