Ready-to-Use System

Substrate additives, Substrates for Microgreens

Cellulose fibers serve as a substrate for seedlings and microgreens or can be mixed into substrates as a structuring agent for better consistency.

As ready-to-use cellulose substrate, they fulfill requirement of highest purity and easy handling. This ensures most homogeneous growth of Microgreens. The fibers are suitable for organic farming and horticulture (FiBL) and moreover even allowed for contact with food stuff.

JRS fibers can also be used as substrate additives. They positively influence the consistency and elasticity of special substrates. Furthermore, they increase the water retention and water availability to the plants.

Organic wetting agent for peat-based substrates

JRS produces the only FiBL-listed, plant fiber-based wetting agent. It is used for organic substrates and as a substitute for synthetic surfactants in conventional soils. The high efficiency allows operating quantities of 0.25% measured by the weight of substrate. Long-chained molecules provide a lasting effect for months unlike synthetic alternatives. The easy-to-use dry powder can also be prepared as dispersion and is completely harmless in terms of environment and human health.

Brown algae granules for Plant strengthening

Brown algae products are of increasing importance in agriculture and horticulture. They contain micronutrients and stimulators for healthy and vigorous plant growth. Their properties have been proven in coastal agriculture for hundreds of years. They not only provide important nutrients for the plants but also support the formation of useful microorganisms for a healthy soil. As a substrate and soil additive, they enable a reduced use of chemical pesticides and mineral fertilizers.

These properties have been scientifically confirmed in many studies and described in specialist literature.

Our brown algae products are harvested in an environmentally friendly manner, processed separately by type of Algae, gently technically dried and milled to the ideal size using the JRS grinding technology.

Cellulose mulch for Hydro seeding

In hydro seeding JRS cellulose is forming a protective layer on slopes and exposed areas.

  Formation of a fine cellulose fleece

  Fast, efficient greening

  Sustainable erosion protection against wind and rain

  Efficient additive in combination with seeds, fertilizers and binders

  Effective physical protection of the seeds

  Highly effective water storage

  Best adhesion to the surface of the ground and reinforcement

Sowing aids / Diluents for Wildflower seeds and Fine seeds

JRS offers a selection of plant raw materials and defined particle sizes that perfectly matches seeds and seed mixes in terms of grain size, shape and bulk density.

JRS products for sowing aids are made from corncob granules or wood. Soft and hardwood granules have a fibrous or cubic structure, while corncob granules are of round shape.

JRS fibers dilute fine seeds for a more precise seed treatment or for easier sowing. Matching the seeds in structure and bulk density avoids separation of the mix for easy handling.

Water reservoir for Pot plants

During transport, storage or in retail markets, the water supply for pot plants can be difficult to manage requiring some labour. As a solution to overcome these efforts, the pot substrate can be dipped in a gel, which provides a long-lasting water reservoir for the plant roots. This can be done by the producers of pot plants prior to the delivery.

Basis of this water-reservoir gel is the JRS hydro colloidal microcrystalline celluloses (MCG), which is activated to form a gel by adding water. The roots can easily penetrate the gel and are supplied with water several days to weeks, depending on the application quantity and plant requirements.
