Microbial Mix

Microbial Mix is a soil mix which acts as a bio-stimulant on the plants, by increasing plant metabolism, so as to increase crop yields and to improve plant quality.


Microbial Mix contains a specially selected strain of beneficial soil microorganisms (Rhizobacteria) to promote germination, rooting and biomass increase. The plants have improved vitality and increased resistance, and their protection against pathogenic microorganisms and fungi is ensured by the natural microbial modifier (Thrichoderma koningii) brought into the soil. The mix acts in symbiosis with the root tissues, by retaining the nutrients in them and stimulating them to synthesize their own plant hormones.

Microbial Mix is based on some essential types of peat – white, black and coco peat, which together with the natural silicate perlite help to retain oxygen and moisture in it. The coco peat further reduces the risk of diseases and provides a buffer zone for the nutrients in the soil.

This natural mix is blended with microelements and minerals, such as nitrogen, phosphorus, magnesium, potassium, copper, iron, manganese, molybdenum, boron and zinc. Their storage and gradual absorption are controlled by the added amount of clay and the precisely calculated value of the pH of the medium.

Microbial Mix contains the exclusive bio-stimulant elfer Bioroot – a product specially designed to stimulate root system growth by improving plant nutrient absorption capacity. Benefits:

  • Root system bio-stimulant
  • Root activator for transplanting
  • Root enhancer
  • It increases the plant’s capacity to absorb the available nutrients and water.

elfer Bioroot bio-stimulant significantly increases the root system by inducing new roots. The new root system is more active and has more absorption capacity.
An increase in the root mass leads to an increase of the upper part of the plant, which in turn leads to an increase in the strength of the plant and more crop productivity.
Plants with stronger and more stable root systems have greater resistance to adverse environmental conditions.

Organic Farming:

BCS ÖKO Garantie confirmed that the application of elfer Bioroot is a contribution to organic farming, in accordance with the requirements of Regulations (EC) No. 889/2008, Annex I (European Union).

Microbial Mix has a stable structure that prevents external factors from altering its beneficial composition.

Xpert Nutrients soil mixes have not been treated and do not contain toxic substances or pesticides!

Manner of use:

Open the sack and distribute the soil mix into the plant pots. Add water and when it begins to drain away, Microbial Mix will be ready for planting.
