There are many different products on the market containing mycorrhizal fungi for use in crop production. Some of these products contain very poor quality material, most probably because of poor quality control, or are mixed with a carrier substrate that is not free of other microbes or which is very difficult to apply.
Symbiom have overcome these problems with their products and Symbiom has consistently delivered very high quality products that are easy to apply. This is why we use their products or fungi produced in their production system for our research that involves field trials with mycorrhizal fungi. After working for over 30 years with mycorrhizal fungi, these products have been the best ones we have tested and working with Symbiom has always been very straightforward and a good experience.
