Question By: Mycorrhizal inoculants are typically applied to the soil around the roots of plants during transplanting or seedling establishment. The specific application method may vary depending on the product, but generally, the inoculant is mixed with water or a carrier material and applied to the soil in the root zone.
Here are some general steps for applying mycorrhizal inoculant:
Prepare the inoculant according to the manufacturer's instructions, usually mixing the product with water or a carrier material.
Create a small hole or trench in the soil near the plant or seedling, about 2-3 inches deep.
Place the plant or seedling in the hole or trench, making sure the roots are in contact with the inoculant-treated soil.
backfill the soil around the roots and gently press down to remove air pockets.
Water the soil thoroughly to help the inoculant to spread through the soil and establish a relationship with the roots of the plant.
For established plants, it's possible to apply a mycorrhizal inoculant as a foliar spray, although it's important to keep in mind this method is less effective than soil application. A less common application method is to apply the inoculant to the roots of the plant prior to planting it.
It's worth noting that the effectiveness of the mycorrhizal inoculant can be reduced if the soil is treated with broad-spectrum fungicides, pesticides or if it's too alkaline. It's recommended to avoid using those before or after using mycorrhizal inoculant.
Ultimately, it's always recommended to check the manufacturer's instructions and recommendations for the specific product you're using. Visit https://www.dynomyco.com/blogs/blog/do-mycorrhizal-inoculants-work for more information.
