How to Do It Series 2 - Episode 2 - Culturing Mycorrhizal Fungi

Great information. Would there be an advantage to using a multiple of species instead of just one?

Thanks @nedobrien6375! I assume you mean plant species, as the inoculants cover a wide diversity of microbial species. Yes, certainly, sorghum-sudan is the industry standard, but to create the most extensive diversity of rhizospheres, you could go with the five cover crop plant families mentioned in this article. However, I would keep the brassica component low. Your fresh potting media shouldn't have many nematodes, and it's possible the bio-suppressive aspects could hinder microbial diversity. "Are you familiar with the research suggesting that when five plant families, including cereals, grasses, legumes, brassicas and chenopods, are combined in a cocktail cover crop, there is an amazing synergistic response? The plant roots begin exuding phenolic compounds (antioxidants), which send the soil life into hyperdrive. All of the multiple benefits of cover crops are then magnified, and this fast-tracks desired changes." blog.nutri-tech.com.au/cover-crop-secrets-1/

great video! how many kg of sorghum sudan root/potting soil should be exracted per ha application, and how soon does it need to be used.

Thanks for the question @johannesmeier4859! Currently, we are working with an application rate of ten litres per hectare of the extracted inoculum. This is based on the compost extract method we showcased in S1E2 and 20 litres of blended inoculated potting mix (including root mass) extracted in 200 litres of water. This is a new technique for us also, so trials are still underway to finalise the best application rates.
