plants when mycorrihza is added and when it is not added and to observe and study the importance it has in our nature and life .

This‚ in general results in a higher yield of the AM crop‚ especially in poor soils. Due to the fact that this is a symbiotic relationship‚ both the fungus and the plant benefit from this
