Mycorrhizae

Mycorrhizae:

Some soil fungi form mycorrhizae (intimate associations between fungi and roots of plants). The fungi acts as additional roots, helping the plant acquire nutrients. Probably, most plants have mycorrhizae, but some mycorrhizae associations, such as those between basidiomycete and beech, birch and pine trees, are particularly abundant in forest soils of temperate regions. The fungal mycelium penetrates the outermost layers of the tree root, but most of the mycelium remains just outside the root forming a sheath that can be up to 40mm thick. Most mycorrhizae forming fungi can not be cultivated in the absence of the plant with which they normally associate. Presumably, the plant supplies some essential nutrients to its fungal partner. The plant can survive without the fungus, but not very well. Such plants are yellow and stunted when grown without mycorrhizae are added they become vigorous and deep green. The fungus supplies the plant with mineral nutrients that are usually in short supply in forest soils.

Some orchids are completely dependent on their mycorrhizae partners. The fungus supplies them with organic growth factors as well as mineral nutrients. These orchids will grow with our mycorrhizae fungi if supplied with certain organic nutrients, including vitamins.

The mycorrhiza fungi are specific group of fungi that act as a symbiot with the plant. In exchange for glucose that the plant produces it will take over and help the plant with a couple of important tasks like:

-Taking in nutrients
-Taking in water
-Soil structure improvement
-Better resistancy against diseases and "bad" fungi

The mycorrhiza looks like a net through the ground and acts like additional rooting. I've been experimenting with it for a while now and I get much better results since.

You might want to look in to it.

This site describes the Mycorrhizas very nicely. :thumbsup:

Actinomycete Gk. aktis - ray, mukes - fungus.

Group of heterotropic filamentous eubacteria tending to form extremely fine ramified mycelia. They multiply by mere breaking of the mycelium or by hyphae. The most common genera in soil (Streptomyces and Nocardia) are particularly able to degrade organic substances which cannot easily by decomposed, thereby producing vitamins and antibiotics. Being aerobic, their presence in a soil signifies good structure and good aeration. They can be symbiotic with some higher plants such as Alnus and Myrica
