Organic Terra Preta

Organic Terra Preta soil (formerly "Riedlingsdorfer Schwarzerde") is a ready-made soil for use outdoors or in a raised bed. It can be used in any layer thickness. When planting root vegetables, a layer of at least 20-30 cm is recommended.

Like any other soil, the Organic Terra Preta should always be covered with organic material - our organic fiber is ideal for this, but any organic material (such as grass clippings) from your own garden can be used. Due to the high proportion of activated biochar, all nutrients from the mulch material are temporarily stored until they are either absorbed by the plants or converted into humus

Attention! This soil stores water extremely well. Always check whether this is necessary before watering.

This product contains stably bound, climate-impacting carbon. This carbon has already been certified and compensated for in the form of CO₂ certificates. Further sales of such certificates are therefore not possible for this product.

Terra Preta

In order for terra preta to develop, the soil system had to be enriched not only with carbon (biochar), but also with a variety of nutrients. The indigenous people of the Amazon region achieved this in the form of a perfect and almost loss-free recycling economy. All waste produced in the settlements - from their own faeces to food scraps, garden waste, fish bones, bone remains and other animal waste - was regularly applied to the garden beds in combination with the remains from the production of plant charcoal. Mud from the Amazon was also used regularly. The biochar acted like a sponge, retaining the nutrients in the extremely permeable soil. Fresh minerals and trace elements were constantly replenished with the Amazon mud, while the fish and animal waste mainly supplied calcium and phosphorus.

All this waste was either applied directly to the ground or temporarily stored in piles and thus subjected to a certain rotting (composting) process before being applied. There was virtually no loss of nutrients, mainly due to the added residues from the production of biochar, and the soil system was thus enriched with more and more nutrients over the centuries.

Many row trials have confirmed that up to 25 kg of vegetables can be harvested per m² in this soil - without fertilization or plant protection. This high fertility does not diminish over the years, but is actually maintained.

In addition, this soil stores carbon - so by buying and using it, you are also actively protecting the climate. The carbon from the biochar remains stable for centuries, and with correct handling (mulching), additional humus (and therefore carbon) accumulates in this soil.

It is simply a good feeling when you not only achieve the highest yields, but also have less work and actively protect the climate!

The horn shavings contained in the soil are a nitrogen storage fertilizer and are slowly decomposed by fungi. A white fungal network is therefore normal and shows the high biological activity.

Following the example of Terra Preta, "Bio Schwarzerde" was developed after many years of testing and research. If this soil is used correctly, long-term fertility is guaranteed and regular use of fertilizer is no longer necessary. This is due to the special composition of the soil (organic compost, organic biochar, clay minerals, trace elements) and a special microbiology (mycorrhizal fungi, N-binding bacteria), which ensure a loss-free soil system and a constant supply of nitrogen as well as an improved supply of nutrients.
