Peat mixture. Master blender choise

Like whiskey makers, blending good peat substrates is a real art that requires experience and knowledge. There are no two identical bogs, each peat has its own characteristics (spirit). Only a good craftsman knows how to make the right choice and the proportions to match the result. (A master blender is an individual who develops specific blended spirits using a combination of spirits with different characteristics). We would like to say that each peat also has its own spirit (word game – spirits and spirit). There is another similarity between these industries. In the production of whiskey, the distinct flavour is found in its peaty taste which is produced in the early malting process by adding peat smoke.

Main characteristics of peat types. What master blender have?

  • – cheaper than others

    – good water drainage

    – good but not excellent water stores

    – stores water-soluble fertiliser better than coarser structures

    – average main physical properties

  • – slightly going to compacting over time

    – does not retain water enough

  • – very high water retention

    – better regarding the stability of the peat structure itself

    – high buffer capacity for nutrients

    – unlock minerals

    – stabilize soil temperature

    – enhance urea performance

  • shrink to form seals

    very heavy, resulting in more expensive logistics

    – poor aeration properties

  • – long term structural stability

    – increased air capacity

    – creates a structural frame of subtrate

    – stores water and fertilisers

    – improves the drainage of water

    – very low proportion of fine particles (< 1 mm) – peat dust

  • most expensive kind of peat

    very heavy, resulting in more expensive logistics

    – poor aeration properties

  • – same price with white milled peat

    – good water drainage

    – good aeration properties

    – stores water-soluble fertiliser better than coarser structures

    – better light absorbtion than white peat

    – more stable structural stability than white peat

  • – slightly going to compacting over time

    – does not retain water enough

    heavier, this was reflected in the cost of logistics

  • – important raw material for s coarse potting and container substrates

    – provide aeration and water transport capabilities

    – improves the drainage of water

  • limited resources

    need for special processing (cutting)

The main limiting factors for better blend selection.

  1. Peat mixture is chosen by the customer. Here, the economic factor often plays a decisive role. Peat types cost a variety of money.
  2. Equipment the grower works with. Trays/pots filling machines have their own requirements. In order to make the process as fast as possible, the peat mixture used must be very homogeneous, free-flowing. Not everything better for the plant is good for filling machines.
  3. Not all peat substrate manufacturers have sufficient peat resources available to provide their factories with all the types of peat they need. For example, if there is white peat, not black, and vice versa.
  4. The manufacturer does not have the necessary equipment to properly handle the required peat types

How to combine the best features of different types of peat?

Substrates based on best selected peat moss – the base for success

If the producer has all the necessary peat types, they are of good quality, properly obtained from the bog, well sifted, have suitable production equipment, then the possibilities are quite wide.

As we said earlier, peat mixing is a special process that comes with experience. Each master has his own idea of the composition that would be used for a particular group of plants. Of course, the agronomist’s advice is important, but knowledge of the specificity of peat raw materials is limited to the master blender.
