Green Cover Seed - PhD. Christine Jones, Webinar - "Secrets of the Soil Microbiome"
This was a fascinating 1.5-hour webinar and I am going to try to provide my highlights from the webinar.
1. Mycorrhizae fungi continue to dominate most soil health discussions - the networks can be tremendously vast -as long as we are priming the biological pump through diversity and no-tilling. What they are finding is that mycorrhizal fungi networks are like the "internet" of the underground world. When you have a well-established fungal network and diversity in planting families - this equates to very beneficial plant health. Also higher nutrient densities for cervids or humans consuming the plants grown in that environment.
2. As this network is established - the roots can "mingle". This does not mean they are touching but more so near each other, and of diverse plant species. The fungal network can then pass microbes from one plant to the next. This allows the plants to be more pest resistant, drought resistant, increased stress tolerance, share nutrients, etc. All of this through expressed communications from the plant and then delivered via the communication stream of the fungal network.
3. An example of a well-functioning system - as described in part 2 - would be during a drought. A non-drought tolerant species can signal its need for help (high stress) during a drought period. The stressed plant can recruit microbes from a companion plant in the network that is better adept at surviving drought conditions. Through this communication, we can and will see increased survival and plant growth efficiencies. This used to be thought a genetic, but it is not a genetic trait - this is all microbial, through the symbiosis occurring in the plants and fungal networks.
4. Another amazing example of how powerful this network is, once established, is the ability to communicate with companion plants - even if they are non-mycorhizal. Brassicas for example (popular food plot crop), are non-mycorhizal. However, when grown in companionship with a diverse species mix, in a well-established fungal network, they can then join and communicate the network - helping to transfer nutrients (plus other advantages described above) and through the "fungal internet", as Ph.D. Christine defines it in laymen's terms.
5. The last bullet is about phosphorus - phosphorus is often bond up in the soil, particularly when soil PH gets below 6.0. One of the most efficient ways (outside of dumping synthetic phosphorus-based fertilizers) to make phosphorus bio-available is through diverse plants and liming to get your PH in an optimal range. Often folks think of Buckwheat as a crop that "mines" phosphorus, but if the buckwheat is then taken off the field - the phosphorus is also removed. If you have buckwheat planted with a diverse mix of other crops, say as a food plot or cover crop and a well-established fungal network, these nutrients can then be distributed to the plants that are signaling their need for that particular mineral/nutrient.
This is the goal of a symbiotic working system, plants sharing what they have an excess of, fungi working to make it soluble/available to the plants in the network, building OM/soil carbon load, and so goes the system.
The most interesting point to the entire webinar (for me) was when someone said "Dr. Christine Jones, you need to write a book", she chuckled and said "it would change every year, we just continue to learn more and we don't know it all" - here is one of the more well-known soil scientists in the world, claiming not to know it all......
Don't buy into the hype of so much that is presented to the "deer" world.
Thank you for following along.
