|
Enhance the water-holding capacity of the soil
|
|
|
Help bind soil particles together, better structure and prevent soil erosion
|
|
|
Have a selective intake of minerals, preventing toxicity from heavy metals
|
|
|
Provide resistance against nematodes to the plants
|
Detailed explanation-1: -Mycorrhizal fungi allow plants to draw more nutrients and water from the soil. They also increase plant tolerance to different environmental stresses. Moreover, these fungi play a major role in soil aggregation process and stimulate microbial activity.
Detailed explanation-2: -Increased drought resistance. Increased pathogen resistance. Increased plant health and stress tolerance. Higher transplanting success.
Detailed explanation-3: -Advantages: relatively easy to culture in vitro; attack infective nematodes in soil. Limitations: poor saprophytic competitor; limited spread in soil. Advantages: easy to culture in vitro; can be applied as seed treatments; reduce plant damage.
Detailed explanation-4: -Mycorrhizal benefits can include greater plant yield, macro-and micro-nutrient uptake, and protection from drought stress and pathogens. Moreover, hyphal linkages shared by two or more plants may facilitate the transfer of resources in a community, or assist in seedling establishment.
