It is a fungi, known as mycorrhiza, that allows plants to obtain nutrients and water from the soil.
These mycorrhiza types have enzyme systems able to break down complex organic molecules and thereby supply the plant partner with N , the most common production-limiting element for plants.
The plant – microbe interaction may also be mutualistic through the mycorrhiza by which the fungal partner supplies nutrients to the plant in exchange for C supplied by the plant.
For growth, orchids need light and moisture as well as a mycorrhiza relationship with a tree or other plant to derive their nutrients.
In addition to intercropping, trees and shrubs (agroforestry) are the anchor perennial species, providing mycorrhiza for mobilizing phosphorus and other nutrients. and these trees and shrubs promote soil protection against erosion by wind and water.
Until recently, it was difficult to procure just the right rhizobium or mycorrhiza for a particular tree species and site.
Norani (1983) confirmed the presence of VA mycorrhiza on the roots of nursery stock.
A preliminary survey on nodulation and VA mycorrhiza in legume roots.
Having spread undetected throughout her body, the developing mycelium of what was possibly an endomorphic mycorrhiza had finally fruited.
