Edasil Clay minerals

Edasil clay 25kg

A natural soil improver with a high binding capacity of minerals.

Edasil Clay Minerals have a tremendous swelling capacity due to the specific plate-like structure and are therefore able to bind together a large amount of water and nutrients. In addition, Edasil contains all of the essential micro-elements in a balanced dose.

Made from a bentonite clay, it contains montmorillonite which distinguishes itself through the excellent binding capacity. This natural source of clay is used for building and improving soils and plant substrates. It supports the development of Micro-organisms in the soil, acting as an aid for compost and doesn’t contain any chemical additives.

Benefits Edasil clay minerals

• Improves light and sandy soils.
• Stimulates activity.
• Improves water balance and absorption/drainage in the soil.
• Improves the effect of fertilisers through its excellent ability to store nutrients.
• Promotes soil fertility by forming stable clay-humus-complexes.
• An ideal composting aid because micro-organisms are promoted.

• Prevents mould and inconvenient smells.
• Better nutrient uptake by plant (through the root system).
• Increases the nitrogen available.


1) Additive for plant/soil substrates. Apply 10-25 kg / m2 thinly to soil surface and rake in.
2) Bokashi composting additive. Add 12kg per tonne (organic matter).

Edasil Clay Minerals

Depending on the type of soil and the application, EDASIL® is either scattered or worked into the soil evenly as fine granules or powder with a fertiliser distributor and must be worked in about 5-10cm with a ripper; then seed the lawn. It can be easily dosed and is low in dust because of it’s fine granulation. The typical dosage is 50-300 g/mÇ respectively 10-25 kg/m3.

Soil is a conversion product of minerals and organic substances (living organisms i.e. worms and bacteria) which is saturated with water and living beings to help permit plant growth.

Mineral Substances = clay minerals

Montmorillonite (main ingredients in bentonites) is a so-called triple layer clay mineral. Because of their disc-shaped crystal structure these triple layer clay minerals have a very high specific structure (600-800mÇ/gram) with the ability to store water molecules and nutrient ions on their surface.

A soils ability to retain water (particulary in sandy soil and especially with strong solar radiation) significantly increases when a triple-layer clay mineral is added, so that the water stored in the soil is available to plants over a long period of time.

Another important characteristic of these clay minerals is their high capacity for ion exchange. So called “crystal mistakes” cause the clay minerals to be negatively charged, which is why they can bind nutrient ions such as potassium, ammonia, calcium and magnesium. A speciality of this bond, is that bonded nutrients are largely protected against being washed out, but can still be absorbed by the plants.

Combined with the minerals they cause: the soil’s crumb structure, its readiness for cultivation, as well as absorption capability, and act as nutrient deposit for plants. By adding triple layer clay minerals into the soil with organic substances plant growth and health can be effectively ensured through better storage of water and nutrients in the soil. These soil properties are achieved with the clay mineral product EDASIL, a bentonite montmorillonite made from choice bavarian clays.

EDASIL® clay minerals are used to improve structure of the soil and to re-balance the mineral content of the soil. These clay minerals have an amazing layered structure which allows them to swell to great capacity. Through this they can absorb large amounts of minerals and water which may otherwise be flushed out of the soil in certain weather conditions. They also contain essential spoor elements in a balanced amount.
