Science Affairs Botany

Under the Integrated Nutrient Management (INM), Mycorrhiza is an indispensable agricultural input. Mycorrhiza is a symbiotic association of fungus with the root of the plant. The benefits associated with such association are:

1. Improved supply of water and nutrients to the plants.

2. Increases tolerance of plants to environmental stress.

3. Protects plant from soil borne pathogenic diseases.

4. Reduces the need for Fertilizer

Explanation:

Mycorrhizae are soil fungi that benefit the soil in many ways. A healthy soil is important for a water-wise landscape. Organic matter, drainage, and plant nutrients contribute to the fertility and health of the soil and plants found therein.

Mycorrhizae literally means “fungus root” and describes a mutualistic association between fungus and plant roots that exists in almost all plants. The plant supports the fungus by providing carbohydrates needed for fungal growth, while the fungus helps the plant by increasing its root surface area.

Potential Benefits of Mycorrhizae:

Enhanced water and nutrient uptake
Reduction of irrigation requirements
Reduction need for fertilizer
Increased drought resistance
Increased pathogen resistance
Increased plant health and stress tolerance
Higher transplanting success

There are many types of mycorrihizae. Remember that most plants naturally contain mycorrhizae and may not benefit from the addition of mycorrhizal fungi. However, in cases where plants are being transplanted from or into sterile soil, adding mycorrhizal fungi may be of benefit.
