HEALTHY (LIQUID) MANURE - A valuable fertilizer.


A well-run agricultural operation uses the natural potentials optimally, so that even without chemical aids good results can be expected. This in addition protects the environment and preserves the basis of life. For a properly functioning agricultural operation the complete utilization of liquid manure is essential.

The aim of the so called "Manure Revolution" is to convert the animal and human waste into a valuable fertilizer, which is not only in the farmers and communities interest - but everyone will benefit.

"Problem Substance" Liquid manure.

Every farmer knows the problems he is experiencing with liquid manure: clogging drains, crusts on the surface and sediments in the manure containers. Then the hard job of stirring the manure before it can be distributed; penetrating, pungent smells in the stables and containers, gas formation in the stables and during the stirring and distribution; damage to plants, roots and soil organisms. In spite of all efforts the fertilizing effects are frequently not convincing compared with the damage - making additional use of chemical fertilizers and pesticides necessary.


"The Troublemaker" DECAY, ROTTING
The main causes of these problems is not the liquid manure itself, but the fact that it is incorrectly decayed. This occurs in the absences of oxygen which causes anaerobic rotting. During an anaerobic rotting process obnoxious gases are released, like hydrogen sulfide and ammonia as well as methane, which does not smell but adds to the atmosphere's hothouse effect. These excretions of the anaerobic bacteria cause further chemical production of poisonous substances etc.. The substances that cause the smell of manure, Idol and Skatol, for example, attract various pests that lay their eggs on it and their larvae are then distributed together with the liquid manure, causing damage to the crops. The rotting bacteria also aid the development of dangerous disease bacteria such as swine fever and paratyphus, which often end up with the farmers animals. Besides this the liquid manure tends to loose its valuable ammonia-nitrogen during decaying. The anaerobic bacteria change the ammonia into nitrate-nitrogen which the plants cannot utilize and which ends up in the ground water. Decay is all-together a life-threatening process and one can understand that rotting liquid manure damages the soil and its micro organisms, the underground water, plants, animals and finally humans at the at the end of the food chain.


"The Natural solution" DECOMPOSING
But there is another way
. The simple and natural solution for changing liquid manure into a valuable fertilizer is the activation of vital processes in it which, however, can only take place in the presence of oxygen. As soon as the anaerobic bacteria are at work they kill off the anaerobic decomposition bacteria and decomposition becomes rotting. Rotting includes the activities of many fungi, yeast’s and other microorganisms as well as various biological processes essential to the balance of nature. Dangerous bacteria are eliminated , and ammonia is changed into ammonia- nitrogen due the action of fungi , giving the plants a steady source of nitrogen. Besides the conservation of ground water the dangerous and pungent gases are eliminated.
Instead, the typical carbon dioxide and humus smells of healthy compost are produced. Vital vitamins such as those of B-complex, trace elements and great quantities of important enzymes are produced. In other words the soil is regenerated by using properly rotted liquid manure. Soil, plants, animals and humans benefit.


Oxygen Through Ventilation?

The usual method of introducing oxygen into the manure is by means of forced ventilation with stirring and ventilating machinery. This is difficult with large amounts of liquid manure, especially when daily stirring is not possible. Then solid crusts form quickly which tend to cut off the oxygen supply even more. In addition the energy costs for such mechanical processes are high and an additional burden for the environment.


Putting Life into the Liquid manure

The best solution would be a simple method which activates the aerobic bacteria without energy costs and environmentally detrimental consequences. Here the Plocher- Energy System can demonstrate pioneering successes. PENAC- G, the liquid manure activator of the Plocher company has the power to activate the oxygenating processes in the liquid manure and by bring new life into it. Through simply stirring-in of some PENAC-G into the liquid manure, an anaerobic situation changes to an aerobic one. The decomposition bacteria die off and the rotting process takes over. In a short time the liquid manure becomes an oxygen-producing and breathing bio-mass The aerobic bacteria now produce carbon dioxide which forms carbonic acid in the manure and so changes the pH values below pH 7. Only at this point can the ammonia change into the valuable ammonia-nitrogen. The emerging algae change the color of the manure to dark green and the substance becomes homogenous. Eventually the crusts and sediments dissolve. Smells disappear and even in the stable a healthy climate is generated. This fertilizer can now be applied to the fields and crops without causing damage to the plants and the environment. Plants will also become stronger and resistant.

Finally overall costs of fertilizing are dramatically reduced and better soil means stronger plants.

The positive results of the use of PENAC-G were recently confirmed in a thesis written for the Agriculture University of HOHENHEIM. A summary of these results, as well as some cost calculations for the use of PENAC products in farming are available directly from:

Aerobic Manure




Little or no smell

Aerobic decomposing bacteria

No dangerous gases



Assimilation of plant available nitrogen to bacterial proteins

Liquid Manure remains liquid and homogenous

No formation of root-inhibiting


No cauterization of plants during application

Promotes the growth of low-growing grasses = good fodder

Healthy cattle due to better stable air and healthy fodder

Application feasible in dry and hot weather

Only small amounts of liquid manure per acre necessary because of good fertilizing effect

Nutritional elements in insoluble form = no danger to ground water.


Anaerobic Manure

(rotting, decaying)


No Oxygen

Pungent, evil smells

Anaerobic decaying, rotting bacteria

Production of Hydrogen Sulfide, Ammonia, Methane and rotting gases.

Large losses of nitrogen


Formation of surface crusts and sediments

Formation of powerful root toxins


Danger of cauterization during application

Promotes the growth of woody high

grasses = poor fodder

Occurrence of cattle diseases due to dangerous bacteria

Application mostly in rainy weather


To achieve a fertilizing effect large amounts of liquid manure necessary


Deleterious substances in soluble form = danger to ground water.
