There are so many different opinions on the use of compost, compost tea, and all the additives that can be put in them that it is very difficult to know what is beneficial and what is not. So I can't give any definitive answers. Having never made compost tea or used any of the "formulas" or additives so often recommended, I can not give personal experience on them either. The best I can tell the scientific data seems to indicate there would be very little chance of adding mycorrhiza fungi successfully. However that is beyond my understanding, I am still trying to understand if mycorrhiza is actually even a physical thing or just a relationship between roots and fungi?
