Toxic nitrogen forms in fresh organic growing media?

If you formulate an organic growing medium by adding starter organic fertilizers, the growing medium should not be used immediately. It should be allowed to “rest” for 2-4 weeks before using it because various microorganism populations that are required to break down complex organic materials into various intermediary forms of nitrogen need to build up.

Until this occurs, there is a possibility that toxic, intermediary forms of nitrogen accumulate in the growing medium until another group of microorganisms build up to continue the nitrogen conversion process.

This is especially true if a customer makes his/her own growing media as prepackaged growing media has had enough time to rest by the time the customer uses it. The following explains this process.
