What Micorrhiza is

Among more than 100,000 different kinds of fungi, there is a small group living under natural conditions in symbiosis with plant roots. This co-existence to the mutual advantage is called Mycorrhiza (Frank, in 1885). About 85% of all examined botanical species are infect-able by the ubiquitär seeming Mycorrhiza fungus. From the mykorrhized root, extremely thin fungus threads (Hyphen) expand into the ground and cause the root surface to enlarge up to a thousand times. The so enlarged surface between fungus and plant leads to an extremely favorable water-   and nutrient exchange. The fungus improves the supply of nutrients and water supply for the plant. Positive by-product is, that ground nutrients or water, otherwise not available for the plants, are utilised. (The reduction of the irrigation and the fertilisation is therefore possible). Among the numerous positive effects for the plant are:

– Increased growth, increased returns

– improvement of stress resistance, e.g., against illness cause, pests etc.

(In exchange from the plant, the fungus receives carbo-hydrates (sugar) which are needed for its growth, but cannot produced by the fungus.

Agricultural value of the product:

The Inokulation of cultivated plants with Mycorrhiza fungi leads to numerous positive effects. There are hundreds of scientific reports confirming the positive effect of Mycorrhiza fungi.

Mycorrhiza fungi - a miracle of nature!

Still an insider tip among bio gardeners – the mycorrhiza fungi. They provide plants with nutrients and help them to grow larger roots.

But what is a mycorrhiza fungus?

Mycorrhiza is translated as “root of a fungus” Effectively it is a fungus which enters “life-community” symbiosis with its host plant. The appearance of mycorrhizae is quite different in the different plant groups. Just as a fruit body is a special organ for the propagation of a fungus, the mycorrhiza is also an organ, which the fungus needs as its nutrient supplier. Here the plant also has a quite positive benefit and is in every way completely ecologically.

Symbiosis between plant and fungus:

Mycorrhiza is a lifeblood between fungi and plant roots, which makes life easier for both organisms. In biology such a life-community is also called “mycorrhizal symbiosis”. Each partner benefits from each other: The fungus absorbs valuable vitamins and sugars from the root cells of the plant, which the plant itself cannot produce because it lacks the necessary  chlorophyll. The plant receives in turn water and nutrients, such as nitrogen and phosphorus from the fungus braid, as the fungi can better brake up nutrients and water in the soil. The subterranean fungus (mycelium) grows with the root of the plant and thus increases its root surface. The plant has now the possibility to cover a more extensive area and penetrate deeper into the ground. It is better fed and is more resistant to weathering, pathogens and pests due to its good nutrition. Even un-favourable environmental conditions such as high salt concentrations and longer lasting dryness in the soil are better tolerated by the plant with the help of the fungus. A simple test with a garden cress with a mycorrhised expanded clay (AGROMYC® VITAL) and with sterile swelling (see picture below) shows after just a few days, that the cress seed seeded with mycorrhiza has larger roots and is considerably stronger.

This symbiosis has been working for millions of years:

In the Central European forests, the trees live, without exception, with mycorrhiza fungi. Of the visible fruit bodies, which are known to us as mushrooms, more than a third belong to the mycorrhiza fungus family. Both, edible fungi, as well as poisonous specimens. Did you know that fungi are the oldest living beings on our planet? 

In the undisturbed nature, the mycorrhizal symbiosis still functions alone. In disturbed soils, on intensively cultivated land or after construction measures, this symbiosis is disturbed. It may take many years, if not decades, before the mycorrhiza symbiosis refreshes, if at all. In organic farming, cultivation areas are therefore inoculated with mycorrhiza fungi in order to re-cultivate soils. There are also various mycorrhiza products for the amateur gardener who have been specially developed for each plant. AGROMYC® VITAL Mycorrhizal Concentrate is the name of our product line, in which vaccines of mycorrhizal fungi are fixed on different carrier materials and thus are present in high concentration.

What is important when using AGROMYC® VITAL Mycorrhizal Concentrates?

If you decide to use our AGROMYC® VITAL Mycorrhizal fungi, the motto is “Less is more”. They need less fertiliser and less water. In the first eight weeks after the application of the mycorrhiza preparation, do not use any plant protection üroduct of any kind and make sure that fungicides (fungicides) do not get into the soil immediately. the future use of fertilisers should be reduced by about  50 per cent.  Use, if possible, only organic fertiliser.

The supply of excessively high doses of nutrients, especially phosphor, can reduce the symbiotic effects of the mycorrhiza, and thus its effect. Since the mycorrhiza fungus is not “consumed” in contrast to the fertiliser, all plants only a single inoculation in  normal cases, unless the plant is reacted. If too little mycorrhiza substrate is used, the effect starts with a delay, as the mycorrhiza takes longer to spread. Too much mycorrhiza substrate does not harm, since it is a purely biological product, which is completely harmless for humans, animals and soil life. If the mycorrhiza fungus   does not find a symbiosis partner, it dies without endangering the soil or plants.
