Zusammenfassung:Fertiliser in the form of granules made of natural raw materials, prepared by mixing 40 to 60% of bird and/poultry excrements with 25 to 50% of fermentation humus with an addition of water, the bulk being shaped into small spheres having a diameter of 0.5 to 5 mm, and the small spheres being dusted by adding 20 to 30% of ground primary rocks and coated with this rock powder, after which this rock powder sets to form a solid coating. The amount of water added to the mixture must be such that the mixture inside the small spheres retains a moisture of 20% or above after the rock powder has set.
