Farmland often harbors a multitude of pathogens which attack plants and reduce yields. A Swiss research team has now shown that inoculating the soil with mycorrhizal fungi can help maintain or even improve yields without using additional fertilizers or pesticides. In a large-scale field trial, plant yield increased by up to 40%.
Well, the AMF only ‘shield’ the plants against fungal pathogens. If there are none and I understood it correctly, the AMF don’t do much.
