Doc explains how Mycorrhizal Fungi Works in the lawn and garden and then does an application of Super Juice with added Mycorrhizal Fungi spores and microbes. He also adds a wetting agent to help water infiltrate the clay soil better. It's a long day of learning, cutting the lawn, and working in the garden.
How it Works -
Mycorrhizal fungi are a fascinating group of fungi that form a symbiotic relationship with the roots of most plants. The word "mycorrhiza" comes from the Greek words "mycos," meaning fungus, and "rhiza," meaning root. This mutually beneficial association between plants and mycorrhizal fungi has been crucial for the success and health of both terrestrial plants and ecosystems for millions of years.
Colonization: Mycorrhizal fungi colonize the soil and develop a vast network of tiny, thread-like structures called hyphae. These hyphae are much smaller than plant roots and can access soil spaces and nutrients that are out of reach for plant roots.
Root Association: When a plant root comes into contact with the mycorrhizal hyphae, the fungi form a physical and functional association with the root. This association can take different forms depending on the type of mycorrhizal fungi and the plant species involved, but the two most common types are: Ectomycorrhizae: These fungi form a sheath around the outside of the root and extend their hyphae into the soil between soil particles. Commonly associated with trees like oaks, pines, and birches.b. Endomycorrhizae (Arbuscular Mycorrhizae): These fungi penetrate the plant root cells, forming intricate structures called arbuscules and vesicles within the root cells. This type of mycorrhizae is more widespread and is commonly found in a wide range of plants, including most agricultural crops.
Nutrient Exchange: The mycorrhizal association enables a mutually beneficial nutrient exchange between the plant and the fungus. The plant provides the mycorrhizal fungi with sugars and other organic compounds produced during photosynthesis. In return, the mycorrhizal fungi enhance the plant's ability to absorb nutrients, especially phosphorus, nitrogen, potassium, zinc, and copper, from the soil. This is particularly important in soils with low nutrient availability.
Water Uptake: Mycorrhizal fungi also help plants improve their water uptake. The extensive network of hyphae acts like a secondary root system, increasing the surface area available for water absorption and reducing water loss by enhancing the plant's drought resistance.
Pathogen Protection: Mycorrhizal fungi can also play a role in protecting plants from certain pathogens. The hyphal network can create a barrier that restricts the entry of harmful soil-borne pathogens into the root zone.
Ecosystem Impact: Mycorrhizal fungi have significant implications for ecosystems. They enhance soil structure and stability, contribute to carbon sequestration, and facilitate nutrient cycling. In natural environments, they are crucial for plant succession and the establishment of new vegetation.
In summary, mycorrhizal fungi form a mutually beneficial relationship with plants, enhancing nutrient uptake, water absorption, and pathogen protection. This association has been essential for the success of plants in various terrestrial environments and plays a critical role in maintaining healthy ecosystems.
