RAG; the quality mark for soil supply and soil improvers

Continuously the utmost is asked from the soil. A higher and better production is expected. With the result that the soil wears. In order to hold back the wear, soil supply and/or soil improvers with the RAG quality mark are used. The soil is so processed, that an optimal structure for the culture is created.

On the basis of a soil analysis, it is determined which soil characteristic should be improved. Does the soil improver have to improve the processing of the soil or does it have to buffer the moisture. Or is it just draining moisture what the soil improver should do. When the result gets out, the suitable soil improver is chosen.

Soil improvement with products with the RAG quality mark are helpful in favourable culture results.

Right organic matter content important for a healthy soil
One of the essential parts of a healthy soil is the organic matter content. Organic matter is necessary for a good connection between soil parts and the humid capacity. In addition to that a right organic matter content raises the capacity for binding nutrient matters. The decayed organic matter also inhibits the development of diseases and pests. In total this provides for:
• Good rooting.
• Healthy air in the soil.
• A soil that can be processed excellently.

Soil supply and soil improvers with the RAG-quality mark really contribute to the construction of the right organic matter content in the soil.

Optimal nutrient medium
On the basis of ‘tracking and tracing' of product and process, the raw materials and substrates with the RAG-quality mark are inspected in the whole chain. The substrate with the RAG-quality mark has amongst others been tested on chemical, physical and phytosanitary requirements. This means among other things that the substrates lack the most occurring quarantine diseases. The supplier sends the analysis report enclosed if the client wishes so. The raw materials that are used, for the production of the substrates, have been tested on the quantity of weed seeds.

The raw materials that are used for the production of the substrates have been tested on the quantity of germinative weed seeds. If the requirement for this is exceeded, such materials are rejected for the application of the RAG-quality mark.

This system of quality control supplies the best possible assurance on:
• Better growth circumstances.
• Good air- and water content in the culture medium.
• Regular supply of nutrients in the soil.

Nothing may be left to chance at soil improvement.

  • Soil supply

    Soil supply is a substrate that is composed of several raw materials. The main raw material is peat. Besides, also compost from municipal waste, composted bark and impoverishment sand is made use of. Eventually the soil supply can also be fertilised with manure or spent mushroom compost. The soil supply is used to compensate the loss of soil by root balls and natural decay of organic matter. There are several types of soil supply. A sandy, peaty, clayey and a standard type of soil supply. The choice depends on the type of subsoil.

  • Soil improvers (Soil supply)

    Mixture of raw materials with a view to executing soil improvement.

  • Bark (Soil supply)

    Composted bark is used as raw material for soil supply or as soil improver. The bark originates from pine trees like Pinus (Coarse pine), Picea (Norway spruce) and suchlike.

  • Compost (Soil supply)

    Compost from municipal waste is composted vegetable-, fruit- and garden waste (Municipal waste). Fresh municipal waste is processed several times till the product compost from municipal waste is produced. Requirements have been made for this composting process and to the product characteristics of the compost, which have been recorded in a quality manual for producers of compost from municipal waste. Compost from municipal waste is used as raw material for soil supply and as soil improver.

  • Heather compost (Soil supply)

    Heather compost is the composted product of heather sods. It is used as soil improver or as raw material for soil supply. Heather compost with a low organic matter content is called heather soil.

  • Frozen black peat (Soil supply)

    Frozen black peat is frozen black peat. The frozen black peat is very suitable as raw material for soil supply or as soil improver.

  • Peat materials (Soil supply)

    The peat materials belong to the basis of soil supply. There are several types of peat materials. The low moor peat is mainly extracted in the Netherlands and is often an important source of both organic matter as Lutum. The peat moor originates mainly from Germany and is an important organic matter source.

  • Sand (Soil supply)

    Sand is because of its chemical, physical and granular characteristics very suitable as raw material for amongst others tree sand.
