The Role of Mycorrhizae in Plant Growth and Soil Health

Geposted von Guy Hyams am

Mycorrhizae and plants have a mutually beneficial relationship that plays a vital role in protecting the health and productivity of our ecosystems. For instance, you can improve your soil and plant health using fungal inoculants that introduce fungi such as mycorrhizae.

These fungi form a network of underground hyphae that help plants access essential nutrients like nitrogen, phosphorus, and potassium, often limited in soil. Mycorrhizae also promotes nutrient absorption and increases water retention, which in turn, improves soil health.

Types of Mycorrhizae

There are two main types of mycorrhizae: arbuscular mycorrhizae and ectomycorrhizae. Arbuscular mycorrhizae are present in over 80 percent of plant species and are closely associated with plant roots. Ectomycorrhizae form a sheath around the roots of woody plants.

Mycorrhizae for plants work by extending the surface area of the roots, allowing them to absorb more nutrients and water from the soil. Additionally, they produce enzymes that help break down organic matter in the soil, releasing nutrients for plant uptake. This leads to healthier and more productive plants, making organic gardening an easier and more rewarding endeavor.

The Symbiotic Relationship

This relationship is vital to the survival of both plants and mycorrhizae. Plants provide mycorrhizae with carbohydrates produced through photosynthesis, while mycorrhizae enhance the plant’s ability to absorb essential nutrients from the soil, like phosphorus and nitrogen. Using mycorrhizal inoculants can help promote the growth and health of plants in various settings, including agriculture, horticulture, and landscaping.



1. Question: Can mycorrhizae increase plant tolerance to environmental stress?

Answer: Yes, mycorrhizae can help improve the absorption of nutrients, water retention, and disease resistance – all of which allow plants to withstand harsh conditions like drought, extreme temperatures, and high salinity.

2. Question: How does mycorrhizae help plants absorb nutrients?

Answer: They do this by extending the surface area of the roots, allowing for increased nutrient absorption and water uptake. Additionally, they produce enzymes that help break down organic matter in the soil, which releases nutrients for the plants.
