Developing Disease Suppressive Soil with Jill Clapperton

In this episode of the Regenerative Agriculture Podcast, John Kempf and Dr. Jill Clapperton, an acclaimed plant physiologist, delve deep into the science of the rhizosphere. Listen to learn about the impacts of sugar on the microbial system, which crops have rhizobia that work well together, and why rapid root growth is key to inhibiting disease. See the complete show notes at regenerativeagriculturepodcast....

I have been really trying to understand much of what this podcast covers over the last year as a newish grower- what I would really love to know is what, from your perspective, is the best resource for learning how to manage plant nutrition. I am always concerned about learning the wrong things. I am huge on testing and analysis- but I want to feel more equipped to know what the results are telling me to change or modify in my protocols from a place of more holistic understanding, and how exactly to do so.

She’s AWESOME

[@anderslangoks3813]

Thanks again for providing this platform for increasing our knowledge about plants and soils.

[@Horse237]

I am looking at her website and integrating her ideas into what I have learned from you. Still studying. I now understand that fields have to be designed so that the bacterial-fungal ratio is best for the crops involved. Berries and strawberries grow best in fungal dominant soil with fungal dominant wormcasrings and compost. Most veggies are bacterial dominant. And the best forage is on pasture land that is 50-50 bacterial and fungal. That forage is superior.

[@richardruss7481]

Most veggies (or most brassicas ) do better when fungi (especially mycorrhizal) are also in the soil and are more nutrient dense and disease free.

[@Horse237]

@@richardruss7481 Yes but pastures need more fungi for better forage and even more for the best berries and strawberries.

[@richardruss7481]

@@Horse237 Pastures need a certain species of fungi, brassicas need different species of fungi, the percentage of bacteria to fungi is not as important (or is misleading) (because it is almost always optimal at near 50 50) as the species of fungi. And, a small percentage of mycorrhizal fungi seems to be beneficial to every plant.

[@Horse237]

@@richardruss7481 Have you studied Dr Elaine Ingham? She says brassicas don't pay attention to fungi. That is because they are cold weather plants and the soil biology does not wake up until 53 degrees F.

[@xxpowwowbluexx]

I really like Dr. Elaine Ingham and appreciate her work, but from watching a lot of her presentations online, it doesn’t seem that she gives very much emphasis to the different TYPES of fungi (for instance, the difference between saprotrophic and mycorrhizal fungi). And that is a little concerning to me.

Thanks for the upload

You spoke of flea beetles being attracted to Yellow however I have the most pressure on my radishes and arugula which are not yellow at all..

[@marynunn1708]

Impossible to overstate how important this research and conversation is. Have Dr Clapperton on more often!

[@xxpowwowbluexx]

Wouldn’t foliar applications of nutrients be outsourcing the jobs of microbes that the plant should be associating with?

[@LouisJordan-ow3jr]

I cleared an oak forest of 100x60' and there was a huge snail problem in the garden I planted. What nutrient or innoculant could I have changed to keep them from eating the seedlings? Perhaps I should have planted seedlings at 14 days old or older because they seemed more resistant one older.

[@theglassgirl420grow3]

Does insect pressure lead to higher brix, terpenes, and mineral content in the plant?

[@jjime1175]

I never hear about the nutritional aspects of the dry matter from cover crops, when I look at certain grasses or legumes some have more phosphorus or potassium than others and to that could be a good or bad thing depending on what the plant needs to produce. If you look at rape forage they are high in sulfur ( good for blueberries) which may be too much after it breaks down into the soil for that specific plant or tree. Just a thought when choosing cover crops other than just the Nitrogen. www.feedipedia.org

[@orsobruno7210]

I am trying to implement all this knowledge into lawn care and rhyzo tree care. Knowingness that the best soil for some veggie is half bacteria and half fungi and knowing that cereals are more or less like grasses I would like to ask if there is someone that has already found the best substrates and the best fungi bacteria ratio for lawns maintenance and tree maintenance.

[@xxpowwowbluexx]

ORSO BRUNO, thank you! This is what I’m trying to do, too, as a homeowner! There needs to be much more focus on this because THIS is where the majority of people are at: battling with weeds and diseases and pests in their lawn. This type of info needs to be distilled down and made readily available to homeowners through clear principles and steps that they can take to fix the damage that’s created by applying synthetic fertilizers and pesticides.

[@xxpowwowbluexx]

In partial answer to your question, I believe Dr. Elaine Ingham has said that a 1:1 fungi-to-bacteria ratio for lawn grasses except for Bermuda grass. Bermuda falls in the same category as weeds, basically, at a very early stage in ecological succession.

[@orsobruno7210]

@@xxpowwowbluexx at this moment I am using a italian product called micosat that cover the whole range of fungus and pgpr. Try it. It is amazing cos the 10/9 @re not spores but crude inoculum.

Quantifying what DISEASE really is ?even healthy entities develop disease sounds contrary but I find disease and it's concept a very broad quagmire of understanding .Maybe we all have disease it's what makes it manifest even in a healthy entity. Now I have to quantify what healthy really means? As in life life is really death really there is no life only death because that's what nature lives on so really death is life and taking them as seperate seems to go against perception. Nothing will live forever so really death is the course of nature .forgive my uncertificated ignorance on this. I try to find the fruit bearing in everything as one should. Thank you.
