Suitable for dairy, hog, poultry liquid manure, penergetic g acts as a catalyst to naturally create an aerobic condition in the slurry, activating beneficial microbes which transform the slurry into a nutrient rich organic fertilizer – which is far more beneficial than the more commonly occurring and problematic untreated (anaerobic) manure or slurry.

Penergetic g is an economical, easy to apply manure treatment method (requiring no capital equipment) used by thousands of dairy farms in Europe (and around the world).



  • Optimizes slurry and liquid manure
  • Stimulates the more complete breakdown of slurry by decomposition/rotting (aerobic process), instead of the more common and less desirable putrefaction & decay (anaerobic process)
  • Overcomes the emission of malodorous gases, including hydrogen sulphide, ammonia & (odourless) methane gas
  • Activates the conversion of ammonia to ammonium (a valuable plant nutrient) resulting in less loss of nitrogen through volatilization
  • Mitigates the formation of a floating crust and solidified sedimentation layers
  • Produces a homogeneous and free flowing slurry
  • Lessens or eliminates the need for agitation of stored slurry
  • Reduces causticity for better compatibility with plants and soil microbes
  • Permits requirements for synthetic fertilizer and farm chemicals to be reduced
  • Reduces the occurrence of harmful insects and insect larvae
  • Limits probability of pathogenic organisms in slurry
  • Stabilizes manure resulting in a reduced risk of nutrients leaching into water resources
  • Optimizes manuring effect which activates the soil and contributes to plant nourishment
  • Creates a valuable organic fertilizer that delivers more balanced nutrients to plants and soil
  • No chemical ingredients, no capital investment and energy consumption reduced
  • Environmentally friendly and ecologically balanced (OMRI listed)


Penergetic g is easy to apply:

  • in the barn effluent channels / alleys
  • through slatted floors into underground pits
  • directly into a storage tank or lagoon


Application may be started at any time – when the storage tank/lagoon is all or partially full or after it is emptied.

Initial use:  For every 100 cubic metres of slurry, mix 1.0 to 2.0 kg
of penergetic g with plenty of water and pour into underground pit,
slurry tank/lagoon or effluent channels.
[Note: 1.0 m3 = 35.3 cu ft. = 265 US gal.]

Each subsequent application:  Add 5 g per livestock unit (LSU)** weekly or 1 kg for every 100 cubic metres of additional slurry or liquid manure generated into effluent channels / alley or underground pit.

e.g.: a cow = 1 LSU; heifer = 0.7 LSU; sow = 0.4 LSU; pig 25-40 kg = 0.06 LSU, etc.


a. In barn alleys or effluent channels without a floating layer

Mix penergetic g with plenty of water in a watering can and pour evenly over the channel or through slatted flooring.  Best results may be achieved by pouring 2/3rds of the recommended dosage at the head of the channel.  In barns with automatic alley scrappers, the scrappers will carry the penergetic g/water mix out with the slurry to the pit or tank.

b. In effluent channels with a floating layer

Poke two holes through the floating layer for each square metre of crust and pour the mixture of penergetic g and water through these holes into the liquid layer of the slurry.

c. In a slurry tank or lagoon

For best results at the outset, pour the penergetic g/water mixture over the stirring mechanism (agitator) while operational.  If no agitator is available, puncture any floating layer present with a suction hose and introduce the penergetic g/water mixture through the hose. Pump sufficient slurry out of the tank or lagoon to fill the suction tank then pump it back into the slurry tank/lagoon. The idea is the get the penergetic g / water mixture integrated into the slurry as much as possible at the outset so as to ensure good results more quickly. In the case of large slurry tanks or lagoons, especially if a thick crust is present at the outset (dairy) or heavy sediment layer (hog), this procedure should be repeated at several locations around the structure.

d. In underground pits and stall cleanout channels

Mix penergetic g with plenty of water in a watering can and pour it evenly over the empty pit or channel.  Repeat this procedure each time the channel or pit is drained.

e. Maintenance application

On an on-going basis, to treat manure that continues to be generated, penergetic g mixed with plenty of water is applied through the slatted flooring or into the manure alleys in the barn.  This maintenance application should be carried out regularly, usually weekly, but at least every 14 days.

Sample Costs:

Dairy: Milk Cow: 2₵ a day per cow ($7.30 / year); Heifer: 1.4₵ a day


Hog:   Sow: 1.2₵ a day per sow; pig (farrow to finish) 42₵ (total cost over 28 weeks).


Cost Savings:

  • no capital equipment (or capital expenditures) required
  • no aeration equipment
  • minimal agitation required (sometimes none)
  • lower energy costs
  • reduced need for barn ventilation equipment & cost
  • no need for lagoon cover (for odour containment)
  • less need for soil incorporation/injection


  • By recirculating treated manure – a higher value, nutrient-rich organic fertilizer (superior to untreated manure) back to the land:
    • need for (and cost of) other forms of nutrients (synthetic fertilizer) is reduced
    • transportation and manure spreading expense reduced versus using less fertile untreated manure
    • disease and insect suppression expenses should also be reduced

≈ Using penergetic g permits manure management to be turned from
a cost centre into a profitable venture. ≈


Penergetic g uses a proprietary process to infuse information from oxygen and minerals into the carrier medium (calcium carbonate). This information activates the aerobic microorganisms, stops the putrefaction process and stimulates the beneficial decomposition/rotting process. Since pig slurry sometimes responds more slowly to the application of penergetic g for slurry and liquid manure, special action properties (information) have been incorporated into penergetic g for pig slurry to accelerate the process.



Penergetic g works so effectively because it activates an aerobic process in the slurry. How is this achieved and why it is advantageous are described below:


Slurry as a “problem situation” requiring resolution
The daily problems involving slurry are familiar to any dairy or pig farmer: blocked effluent channels, floating layers and solidified sedimentation layers in the slurry tanks, the need for extensive lagoon agitation before applying the slurry, an acrid, pungent smell in the area of barns and pits, gas emissions during agitation and application of the slurry, burning and scorching of the crops after application and many other problems. Often despite the farmer’s best efforts, the slurry fails to produce the desired fertilizing effect. This leads to the application of additional fertilizers and other crop protection measures.

The underlying problem – putrefaction
Typically, slurry will become a problematic waste product when conversion takes place by means of putrefaction processes.  This involves decay under anaerobic conditions, i.e. in the absence of oxygen.  Anaerobic conversion of slurry leads to the development of malodorous gases, including hydrogen sulphide and ammonia, and (odourless) methane gas.  Also problematic, the odour carriers in manure – indole and skatole (3-methylindole) – attract harmful insects.  These insects lay their eggs in the slurry, and the subsequent larvae often remain in the slurry when it is applied on the fields, leading to crop damage and the need to apply pesticides.  Furthermore, the valuable substance ammonium nitrogen is lost in the anaerobic slurry, because ammonium is converted into ammonia, through volatilization, and consequently is no longer available as a nutrient for plants.

Oxygen through aeration?
The conventional method of introducing oxygen into the slurry involves mechanical aeration by means of stirrers or compressors. However, this technical method becomes problematic when dealing with large quantities of slurry which cannot be stirred effectively every day. Floating layers then quickly form, further sealing off the slurry from the oxygen supply and thus strengthening the anaerobic environment. Also, the annual energy costs for stirring/agitation operations can be considerable.

The natural solution – decomposition
But there is another way! The simple and natural solution to turn slurry into a valuable organic fertilizer involves activating decomposition processes in the slurry which only take place with oxygen. The decomposition processes involve mould fungi, yeasts and many other microorganisms and include several biological processes which are absolutely vital to maintaining a state of equilibrium in nature. Mould fungi very quickly bind any ammonia which is present in the first stage of the decomposition process to form ammonium nitrogen, which is subsequently available to plants as a slow release source of nitrogen. The harmful and unpleasant biogases are also largely eliminated, providing for a noticeable difference in the pit and during application. Healthy, decomposed (rotted) slurry thus constitutes an important element of a closed substance cycle management system which benefits the soil, plants, animals and humans alike.

Activating sludge
The best solution is a simple method which activates the aerobic bacteria while avoiding the use of external energy and other factors detrimental to the environment. Penergetic g possesses the specific active properties of oxygen and reactivates the life processes in slurry. The putrefactive bacteria die and the oxygen which is present in the slurry is aerobically activated. An oxygen-producing and breathing biomass quickly arises. The micro algae which develop change the colour of the slurry to dark green and the work performed by the bacteria renders the slurry homogeneous. In the course of time, existing floating layers and sedimentation layers dissolve. As a natural side-effect of these processes, the smell is diminished. Using the decomposed slurry produced with penergetic g enables the quantity of commercial fertilizer used to be reduced.
