Soil volume and root mass
Due to mycorrhiza plants can explore a larger volume of soil (fig. 1 and 2) increasing their nutrient and water supply. The plant absorbing capacity rises up to 10000 times. The root also increases its mass (fig. 3).

In the diagram below: a scientific definition of the suction capacity of the roots with the VA-mycorrhizae and without it.

A one centimetre long root is taken for a scientific analysis. Without mycorrhiza the root plants can withdraw water and nutrients from the soil volume of 1.8 cm3. (Fig. 1) Due to mycorrhizae the processed soil volume increases significantly. Fig. 2 shows the results of the effect of mycorrhiza after 6 weeks of the symbiotic infection: the volume has increased up to 12.6 cm3. After 12 weeks from the start of the test the soil volume has already increased to 201 cm3. (Fig. 3)
Further increase of the processed soil volume can be considered only hypothetically. Scientists are of the assumption that the soil volume can be increased up to 10 000 times.
