Mycorrhiza...
"Endomycorrhiza" is a specific type of mycorrhiza, and "arbuscular mycorrhiza" is just a more specific name for endomycorrhiza.
Arbuscular mycorrhiza (AM) is a mutually beneficial partnership between beneficial fungi and plants. - the plant gets something it needs from the fungus (mostly soil nutrients) and in exchange the fungus gets sugar or carbon.
In just one handful of good soil/coco there are more than 100 million bacteria, several miles of fungal filaments, and another million of algae, protozoa, and nematodes combined. This diverse community is responsible for nutrient cycling and storage and provides competition for disease causing organisms. Soil fungi are the dominant residents of this community, contributing over 50% of the soil biomass. The obvious stars of this living soil are a specialized group of beneficial soil fungi that form an intimate relationship with plant roots. This relationship is called mycorrhiza. Mycorrhiza plays a key role in plant-soil health and functioning.
The AM fungal hyphae increase the amount of soil that the plant roots can "mine" for nutrients and thus increases the soil nutrient uptake. This works most effectively on nutrients that are poorly mobile in the soil. Phosphorus is a particularly "sticky" nutrient and extremely important in plant nutrition so it gets a starring role but mycorrhiza has also been shown to increase the uptake of other poorly mobile nutrients.
Watch Phosphorus
Fertilization Phosphorus plays a major role in the establishment and functioning of the symbiosis. High phosphorus fertilization limits mycorrhiza effectiveness, but low to moderate levels of phosphorus or the use of slow release forms such as rock phosphate maximize plant benefits from mycorrhiza.
Increased Drought and Pest Tolerance
Along with accessing more nutrients, the hyphae also allow greater access to water. In addition, the extensive hyphal network block pest access to roots. The improved plant nutrition of mycorrhizal plants also boosts the plants natural ability to fight drought and pests.
Increased Tolerance to Toxic Heavy Metals:
Mycorrhiza alleviates root stunting typically caused by toxic metals, thereby increasing nutrient uptake. AM fungi may also bind metals in the root zone and alter the plant cells ability to capture the metals.
Improved Soil Aggregation
The AM fungal hyphae has also been shown to excrete gluey sugar based compounds termed "Glomalin" which helps to bind soil particles and create stable soil aggregates, which gives the soil structure and improves water and air infiltration as well as enhance carbon and nutrient storage.
Enhance Biodiversity of Soil Microorganisms
The presence of mycorrhiza also increases the biodiversity of soil microbe populations, which creates a healthy soil ecosystem. What a healthy soil ecosystem means to plants is improved nutrient cycling and retention, improved air and water relations, and importantly resistance to invasion and establishment of disease causing organisms.
BOOST PLANTS "IMMUNE SYSTEM"
All of these benefits are actually interrelated and all work together to make the plant healthy by recreating a "Living Soil".

How much Mycorrhizae do I need?
Specifying Mycorrhiza, or more specifically, mycorrhizal inoculant (inoculum and inoculant are the same) is like specifying "grass seed." You must specify the right kind in the right amounts in the right form. Just like you would not specify "pounds of grass seed product" per acre you need to specify numbers of ENDO mycorrhiza propagules per acre.
Remember; ECTO mycorrhizal spores will not benefit your ENDO mycorrhizal plants. If you wish for the benefits of mycorrhiza to Pines, Firs and Spruces and certain Oaks you would specify ECTO mycorrhiza as spores. For planting individual seedlings it is most cost effective to apply the correct mycorrhiza or a cocktail of both ENDO and ECTO mycorrhiza to each seedling with a root dip. A mycorrhizal material that does not clarify the specific amount of each kind of spores or propagules in its' inoculants may be "watered down" with cheap material that is not of benefit to your target plants.
This fungus is wholly dependent upon relationships with higher plants and attaches itself to roots in order to obtain carbohydrates which the plant provides. In exchange, mycorrhizae perform a myriad of chores to protect the plant and encourage growth. Most importantly, it grows a complex network of fungal filament that can mine a far greater area of the soil based moisture and nutrients than a naked root. (up to 50 times more area). It also produces a complex by product known as "glomalin" that improves soil structure allowing greater movement of moisture the topsoil and into natural aquifers.
Glomalin is produced by Arbuscular Mycorrhizal Fungi (AMF). Discovered by NRCS Soil Scientists in 1996, "Glomalin", was noted by two characteristics; The first was the apparent abundance of this material that was produced by AMF and the second was the "toughness" of its molecular structure. It was observed that higher levels of "Glomalin" improve water infiltration, increase soil permeability to air, promote greater root development, higher microbial activity and greater resistance to surface sealing (crusts) and erosion (wind / water). It is thought that "Glomalin" helps protect the filaments or hyphae produced by mycorrhizal fungi that collect moisture and nutrients for the host plants. The plants in return, supply large amounts of carbon to the fungi, which in part is used to produce "Glomalin". The carbon sequestration resulting from this process can reach 40% or greater of the total carbon retained within the plant itself.
Limit Use of Fungicides
Some fungicides have been found to damage AM fungi.
Limit Soil Disturbance
Severe disruption of the soil hyphae limits nutrient and water movement into the
plant root.
