­ higher stress tolerance against dryness
­ loss of nutrients
­ salinity and heavy metal pollution

Under stressful conditions Mycorrhiza has these positive effects:

­ raises the chance that new plantings will thrive
­ better resistance against parasites including harmful mushrooms or nematodes
­ for year-round plants, only one application of Mycorrhiza is necessary because the Mycorrhiza stays in the   soil all year

How does agriculture affect Mycorrhiza?
Fertilizers: The use of fertilizers containing strong phosphates reduces the amount of Mycorrhiza in the soil, causing the Mycorrhiza to lose its effectiveness.

Turnover: Rototilling, shoveling, or plowing the ground in any way, particularly in construction, disperses and weakens the Mycorrhiza.
Where has Mycorrhiza already been used?
Our customers have experienced:

· faster-growing indoor and balcony plants
· more beautiful gardens with herbaceous plants, tomatoes, flowers, particularly roses
· better chances of survival for plants after home improvements
· nicer lawns on playing fields and parks
· stronger levees during and after flooding
Are there any known negative effects?
No, at this time there are no known side effects. In the worst case, there is no effect because the plant has no symbiosis with Mycorrhiza. Reasons for no symbiosis could be that the plant is incompatible with Mycorrhiza, or that the environment is unhealthy due to all-year frozen ground, or toxins. Our knowledge to date says Mycorrhiza can not damage plants, animals or humans.
