Mycorrhizal fungi increase the surface absorbing area of roots by 100 to 1,000 times, thereby greatly improving the ability of the plant to access soil resources. Mycorrhizal fungi increase nutrient uptake not only by increasing the surface absorbing area of the roots, but also release powerful enzymes into the soil that dissolve hard-to-capture nutrients, such as organic nitrogen, phosphorus, iron, and other “tightly bound” soil nutrients. It is a powdered product applied through the soil.
