Success with penergetic g in the rotting of long straw

The rotting of long straw is much more time-consuming than the rotting of short straw because the straw is not split. With penergetic g, the rotting was concluded within a short time.

The 40 cows on Ueli Keller's Swiss farm are kept in a barn in which the cubicles are strewn with relatively long straw. In addition to the long straw, which is difficult to rot, there is a cross channel on the farm, which can only be drained using a rinsing process with the slurry barrel.


Weekly 12g of penergetic g per livestock unit

Just 4 weeks after the start of treatment, the first bubbles were arising in the slurry pit. Mr. Keller told us that he had never seen this in his pit, although he had already used slurry-processing agents before. Thus, with the product from Penergetic Int. AG, we helped to bring the rotting bacteria to an enormous activity and were able to achieve a first success after only 4 weeks.

On August 20, Mr. Keller explained that the flowability in the canals had improved considerably! In addition, the smell of ammonia in the barn has also been reduced, which is of course good for the animals and the farmer. 

This is due to the use of penergetic g.

The ammonia of the fresh manure and the air oxygen chemically unite. This, in turn, leads to more ammonium in the liquid manure. In these times, this is an essential advantage, because in many cases the nutrient balance on farms means that artificial fertilizer can hardly be bought in addition.

Condition of liquid manure after four weeks

At the end of September 2011, Mr. Keller told us that the slurry was much more homogeneous and flowable during spreading and that the smell was less. This is a proof that within 3 months with penergetic g we achieved a faster and better rotting of the long straw and the slurry. Thus, the basic product liquid manure could be upgraded to a high-quality fertilizer.

Conclusion of the test

  • Rotting of longer straw is possible
  • Better flowability of the slurry
  • Homogeneous, active slurry
  • Less odour
  • No burning of the plants when applicated as fertilizer
