Can someone explain to me this micro herd and organic growing.Do you have a micro herd if using chemical nutes. Just not up on this stuff Thanks Showgirl

What are mycorrhiza?
Mycorrhizal fungi are a group of soil fungi that infect the roots of most plants. The fungi is not a pest or parasite as it supplies the plant with nutrients like phosphorus, copper and zinc, as well as increasing water availability. The plant supports the fungus with carbon in the form of sugars. This symbiotic relationship does not affect the plants, as they produce excess carbon. In fact, lack of water and nutrients is more often the limiting factor to plants’ growth and establishment. Mycorrhizal fungi are found in most environments, although their importance is greater in more extreme environments, where nutrients and water may be limited. There are very few plants that do not form mycorrhizal associations at all, although most can grow without it. In plants that have been infected by mycorrhizal fungi, the fungus is actually the chief method of nutrient uptake, not the roots.

There are several types of mycorrhiza, the type that we are interested in are by far the most common and are called arbuscular mycorrhiza (AM). This type of mycorrhiza is invisible to the naked eye but forms a fine mesh through the soil. They enter the cells of the roots where they form branched arbuscles within these cells, this is where the exchange of nutrients and carbon occurs.

Thanks showgirl for raising this

It's a live topic for everyone cos as I understand it our collective knowledge around the 'microherd' is advancing all the time

Amazing little fungi even made land-life on earth possible, evolving along with the plants. I look at my little pack of Rootgrow and get amazed at life

I only heard of this stuff last year and it's got me fascinated - the people on 420, especially in the Organic Forum have opened my eyes to so much

Arbuscule
