Mycorrhizae

The term “mycorrhizae” does not refer to a type or species of fungus, but rather to the interaction between the fungi and the plant’s roots. When it was first described in the late 19th Century by German scientists, the interaction was thought to be parasitic, with the fungi stealing carbohydrates from the plant and giving nothing in return. It was later discovered that this relationship is mutualistic, benefiting both parties. The plant gives the fungus energy in the form of carbohydrates; the fungus, in turn, provides the plant with increased uptake of water and nutrients, such as organic nitrogen, sulphur, and phosphorus.

Mycorrhizal associations are generally categorized into two groups, based on whether the fungi actually penetrates the cells of the plant (known as endomycorrhizae) or the fungus simply colonizes the root zone without actually entering the plant (ectomycorrhizae). They can be applied at the time of planting or incorporated into the soil using tools like the Air-Spade.
