Bio Compost

Bio compost is a "young" compost with a much higher nitrogen content and a much higher proportion of organic matter. As a result, Bio compost has an extremely good, instantly visible fertilizing effect and is ideal for the use in urban gardening. This fully mature compost has a very low content of salts and heavy metals and at the same time a high content of nutrients, which guarantees an optimal and natural nutrient supply for the plant. Due to the high biological activity the soil life is promoted and the humus content of the soil is increased. In contrast to peat, the soil structure gets sustainably improved and the water balance is regulated since compost can store a lot of water and slowly returns it to the plants.

The compost used in the production of our Hortisol corresponds to quality class "A +" according to the composting regulations and is suitable for organic farming.



Wooden Fibers

Wood fibers should at first loosen the substrate and promote the aeration of our Hortisol. This prevents a fast compaction of the soil during the cultivation of the plants and facilitates the spreading of a healthy and strong root braid. It also acts as "food" for microorganisms living in the soil. We replace the common coconut fibers, which have a negative climatic quality due to the long transport distances, by the wooden fibers.



Bio Char Coal

Bio char coal is not a nutrient, but because of its large surface is an optimal habitat for desired aerobic microorganisms! Preserved nutrients are initially stored and can therefore no longer get lost. The nutrient supply is significantly increased in our Hortisol. The coal is first "charged" with nutrients and microbiology. Only when the coal is saturated and "activated" it can also become active and unfold its positive effect.

Thanks to the application of the bio char, soil fertility is further improved in our Hortisol. This is reflected in an improved soil structure, an increased water absorption capacity and an increased water storage capacity. The plants become more resistant to diseases and pests. This means that the plants grow healthy and the yields are stable, especially in the case of cultivation mistakes.



Brick gravel

Pure clay roof tile production waste is broken and sieved to the grain size we are looking for.

It is contained in our Hortisol as an additive and replaces the frequently used Perlite. The split acts like Perlite to improve the soil structure and at the same time it is able to store water and release it slowly to the plants. 1 m³ saves up to 350 l of water. Microorganisms can also settle very well in the porous surface, this also promotes soil life.
