EdaBiom Microbial Substrate
Price range: CHF 14.65 through CHF 114.00
The EdaBiom microbial substrate contains the microorganisms required for the brewing process. The EdaBiom microbial substrate meets the highest quality standards for promoting the natural edaphon—the totality of soil biota—and is reflected in the high diversity of beneficial microorganisms. Ongoing chemical-physical and biological tests continuously guarantee the high quality.

Organisms in the EdaBiom microbial substrate
The EdaBiom microbial substrate contains a wide range of beneficial microorganisms that function as a community in constant communication with each other. The following organisms are included in the EdaBiom microbial substrate:
- Bacteria
- Fungi
- Protozoa
- Nematodes
Application rate
The required amount of EdaBiom microbial substrate depends on the EdaLife brewing system model. The quantities are shown in the table above.
Shelf life
Maximum 3 to 4 months
Storage temperature
Store cool and moist; protect from drying out
Storage
Store protected from sunlight
Oxygen
Do not stack bags
The compost determines what ends up in the tank. In a germination trial at ZHAW Wädenswil, all six tested compost tea variants were above the water control in root weight of cucumber seedlings—even those with no nutrient addition at all. What else the trial shows: Inoculate seeds with compost tea.

Bacteria
Bacteria are the last element in the food chain, decomposing organic matter to absorb nitrogen, carbon bonds and other nutrients, which are then fixed in the organisms. When bacteria are consumed by other organisms (protozoa, nematodes), they then become plant-available (mineralised).
Since the bacteria themselves are attached to the soil particles, the nutrients they trap remain in the soil instead of being washed out, as is the case with mineral fertilisation.
Protozoa
Protozoa feed mainly on bacteria, so their quantity is directly related to the number of bacteria. As a result, the immobilised (not plant-available) nutrients in the bacteria and fungi are mineralised and thus plant-available. Since bacteria and fungi mainly reside in the root zone (rhizosphere), the unicellular protozoa are also there and supply the plant with available nutrients.
Studies show that protozoa graze the bacteria at the rhizosphere (rhizobacteria) and influence the bacterial community at the rhizosphere. The protozoa indirectly induce the formation of new lateral roots by changing the bacterial community and thus the excretion of further plant secretions (exudates), plant growth is promoted.
Fungi
Fungi are able to transport nutrients over long distances because of their longitudinal growth compared to bacteria. Fungi, unlike bacteria, break down hard-to-digest food such as lignin, chitin (from insect shells), animal bones or toenails and fingernails. They also have the ability to penetrate hard surfaces.
Phosphorus is very often chemically bound in the soil and not available to plants. Fungi are able to locate it, release it from the bonds and transport it to the roots, which is one of the main functions of fungi. Nitrogen in the form of ammonium (NH4+) is also released by fungi in acidic environments. One form of fungi is mycorrhizal fungi, which live in symbiosis with plant roots. At least 90% of all plants form a symbiosis with mycorrhiza.
Nematodes
Nematodes are undissected, blind nematodes that, together with protozoa, mineralise (make available to plants) the nutrients found in bacteria and fungi.
Nematodes are the main consumers in the soil. In addition to the parasitic nematodes that feed on plant roots, there are also nematodes that feed on bacteria (bacterivorous) and nematodes that feed on fungi (fungivorous). Both types mineralise the nutrients found in the smaller organisms. Predatory nematodes feed on protozoa, algae and other organisms.
Root-feeding nematodes are no longer present in compost that has reached a temperature above 55°C for at least three days.
