Why Mycorrhizae is Necessary for Agriculture

There is no doubt that bio fungicide mycorrhizae play an important role in plant growth. They help build soil aggregate structure to provides plant roots with a better & healthy environment to healthy and strong growth. Their symbiotic relationship with plants helps them access extra water and nutrients sources in soil.

Mycorrhizae is a symbiotic association between a fungus and a plant. The term mycorrhizae refers to the role of the fungus in the plant’s rhizosphere, its root system. Mycorrhizae play important roles in plant nutrition, soil microenvironment.

Mycorrhizal fungi have existed more than 450 million years, they appeared at the same time as the first plants appeared on dry land. “Myco” literally means “fungus” and “rhiza” means “root”, they form a network of filaments that associate with plant’s root system and develop a symbiotic association called “mycorrhiza”, thus plants and mycorrhizal fungi make up a single working network in nature.

How does Mycorrhizae work

A mycorrhiza grows after the germination of a fungal spore. From this spore emerge threadlike organisms that gradually penetrate the root epidermis (form hyphae). This creates a symbiotic relationship increasing the plant’s ability to uptake fixed nutrients and water, improving plant performance.

Mycorrhizal fungi increase the surface absorbing area of roots 100 to 1,000 times, thereby greatly improving the ability of the plant to access soil resources. Mycorrhizal fungi increase nutrient uptake not only by increasing the surface absorbing area of the roots but also release powerful enzymes into the soil that dissolve hard-to-capture nutrients, such as organic nitrogen, phosphorus, iron and other “tightly bound” soil nutrients.

Types of Mycorrhizae

Type-of-mycorrhiza fungi

1. Endomycorrhizae

Endomycorrhizae

Endomycorrhizal fungi are one of the major types of known mycorrhizae. Unlike ectomycorrhizae which form a system of hyphae that grow around the cells of the root, the hyphae of the endomycorrhizal not only grow inside the root of the plant but penetrate the root cell walls and become enclosed in the cell membrane as well.

This makes for a more invasive symbiotic relationship between the fungi and the plant. The penetrating hyphae create a greater contact surface area between the hyphae of the fungi and the plant. This heightened contact stimulates a greater transfer of nutrients in plants.

Endo mycorrhizae have been divided into 5 groups: Arbuscular, Ericoid, Arbutoid, Monotropoid, and Orchid mycorrhizae.

2. Ectomycorrhizae

Ectomycorrhiza

Ectomycorrhizae is a form of symbiotic relationship that occurs between a fungal symbiont and the roots of various plant species.

Ectomycorrhizal fungi do not penetrate into the root cell walls, they form a sheath around the root known as a fungal mantle as a nutrient exchange network. Ectomycorrhizal fungi only colonize the roots of trees including species from the birch, dipterocarp, myrtle, beech, willow, pine, and rose families.

Benefits of Mycorrhizae in agriculture

benefits of mycorrhizae fungi

Mycorrhizae induce plants to absorb more nutrients and water from the soil. They also increase plant tolerance ability to various bad environmental stresses. In addition to this, Mycorrhizae also play an important role in the soil structure process and stimulate beneficial microbial activity.

Based on these two characteristics, we divided functions into two parts:

For Soil

  1. Increase soil’s water & nutrition holding capacity.
  2. Improve soil porosity and permeability.
  3. Develop soil microenvironment, promote higher microbial activity, and nutrient cycling.

For Plants

  1. Increase roots establishment and survival at seeding or transplanting.
  2. Improve the plant’s mineral absorption capabilities, access many extra nutrient sources share with colonized plants.
  3. Increase plant resistance ability to soil diseases, virus, drought & salt stress, and pests, etc.
  4. Increase the plant’s root system of healthy development.

The optimum supplements to mycorrhizae are Bacillus subtilis, Trichoderma harzianum

Mycorrhizae’s ability is to regulate biological diversity in soil, develop a positive microenvironment.

Bacillus subtilis can improve plants uptake nutrients efficiency, increase roots growth, and protect roots away from soil pathogens.

Trichoderma harzianum has super soil adaptability. Good effect on soil conditioner and control soil-borne diseases. It also can increase root systems development.

In general, the more biological diversity of microorganisms, the more advantageous it is for growing.
