What tips should I know when working with / applying mycorrhizae?

1. The main goal of any mycorrhizal application is to get the product in the root zone of the plant. Since the mycorrhizae germinate in the presence of root exudates this is the key to successful  inoculation.  We have formulated our products in many different forms (granulars, powders, liquids, etc) to be easier for you.   You know your equipment and soil the best.  We are here to help if you have questions.

2.  Mycorrhizae are probably more hardy than you might think, which has helped them to survive the last 450 million years.  There are some conditions to avoid:

  • High temperatures of 140 degrees F and above can kill the mycorrhizae, which could be important to  other manufacturers that might be looking to process the mycorrhizae into pellets for example or to people who want to use before Composting.
  • Not all, but certain Fungicides can also damage mycorrhizal fungi.  Please see our List of Fungicides and their know effects, to help you pick a mycorrhiza friendly fungicide.
  • Mycorrhizal fungi actually attach and become part of the plant, they are not free living soil organisms, they require that symbiotic relationship, meaning they will stay with the plant for the life-cycle of that plant. When annual plants die, or a field is tilled, etc those mycorrhizae do not remain indefinitely, they die along with those plants.

3.  High levels of available Phosphorous does not harm or kill mycorrhizae, but it can slow there progress. One of the main functions of mycorrhizae is to extract phosphorous.  However, if there is already an over abundance of phosphorous available to the plant the mycorrhizae have to reason to “go to work” so to speak.  This means they won’t be performing some of their other important tasks like water uptake, and other nutrient extraction as well.  You really want to keep  available phosphorous at a low to moderate level.  This is most important at the time of inoculation when those spores are trying to attach to the plant and assimilating to their new environment.  Click Here to refer to our Phosphorous Tips.
