Humus build up in the soil

Soils useable for plant growth of any types (agriculture, forestry, gardening etc) contain mineral as well as organic components. The mineral components become available through mineralisation of the rock. The organic components are derived from the perishing of all life forms and become humus.

How does humus originate?

Many of our agriculturally used soils have only 1-2% of humus left.  Plant feeding is done by mineral fertilization and the soil is used merely as root support.  Sustainable agriculture will only function with a higher humus content and organic fertilizing through slurry, manure, horn-meal.

Mineral or organic fertilization

To increase the humus in the soil the regular application of good compost is necessary. Additionally the supplementation of trace elements in the form of primeval stone meal is of great benefit. This way within a few years the soil can become fertile again.  The quality of of food, plants and vegetables grown on such fertile grounds is dramatically increased in comparison to soils of nowadays.

How can one increase the humus content?

Simultaneously petrification processes must be avoided as they build up poisonous material and attract pathogenic bacteria.  This is guaranteed through sufficient oxygen availability in the compost, homogenous slurry and manure as well as in the soil itself. 

Avoid rotting

Optimised Composting Processes


During a successful composting process a lack of oxygen must never occur.  This one achieves through the correct handling of compost heaps and through the addition of penac-k.

Good management of compost

The oxygen information will also work under less ideal conditions i.e. also stacked compost  with the help of penac-k.
on the bedding of the stables will initiate the start of this composting process. Due to that, break down of nitrogen into ammonia and other bad odours are reduced drastically. Less ammonia is beneficial to animal health as well as the humans working in the stables. A pinch of penac-k in your bio bin will also reduce bad odours.

Preparation of raw materials for composting

Organic matter on the fields, especially after harvesting, will also be composted by application of penac-k.
 A single application of penac-k guarantees activation of all microbes and sufficient oxygen availability. These harvest remains, after a short while, can be worked into the ground.  In the same manner one optimises green covers.

Compost harvest remains on the field

Finally penac-k is suitable as a soil activator. The application over the whole soil surface, preferably in autumn, will not only guarantee a perfect decomposing instead of rotting of all organic material in the soil and therefore in spring release the proper nutrients.
