Popkes deep pit hog barn.
On a hog barn project in Northwest Iowa, big things are happening beside a deep pit hog barn. In the middle of July, Wyatt Beyer spent the week pumping pig manure from the deep pit through our manure separation trailer to be applied via SDI (subsurface drip irrigation) to a growing crop for fertigation through a NutraDrip irrigation system. This system is applying this liquid gold at 35 gallons a minute to beans and alfalfa.

To start, the manure is pumped from the deep pit to the screw press. This removes most of the solids, which will be left in a dry waste pile. The dry solids do not usually smell, and can be spread on the field, or used as compost.

The liquid from the screw press then go to a holding container.
From the container the liquids are run through microfilters. These clean out any solids the screw press misses. The result is a liquid that can be run through irrigation. It is stored in a clean manure holding tank until ready to apply.

From there it is pumped to the subsurface drip irrigation system where it is blended with water to be applied on the field as nutrients to the growing crops. Bonus, it doesn’t smell when it is being applied.
Conclusion
Hog manure is turned into an in-season fertilizer when the manure separation trailer is used to pull manure from the deep pit hog barn, separate the liquid, and apply it for a non-smelling fertigation source to crops.
