The Fallacy of Mainstream Potassium and Nitrogen Fertilization with Richard Mulvaney

In this episode of the Regenerative Agriculture Podcast, John Kempf interviews Dr. Richard Mulvaney to discuss nitrogen uptake in crops, how soil can provide most of the needed nitrogen, the conditions that can make nitrogen fertilizer applications a waste of money, and the fallacy that applied nitrogen builds soil organic matter. Dr. Mulvaney also describes the significant amounts of potassium that are plant-available in the soil and the “potassium paradox”, the damaging cycle that can be developed by applying potash. Listen in to learn how to address nitrogen and potassium in your soils to save money and improve yields.

Main take away for me in this one was the presence of the amino sugars, or specifically the term amino sugar. And the reminder that soil life is so important to the system. One of the main amino sugars being N-Acetyl-d-glucosamine, which is the main component of chitin. Chitin is found in the exoskeletons of insects, the cell walls of plants and fungi, and certain hard structures in invertebrates and fish. In terms of abundance, chitin is second to only cellulose. If your fields are devoid of insects, fungi, and other soil life you won't have that N from the chitin cycling through your crops.

This is such an important comment, Chitin Chitonase CGM is a whole rabbit whole on its own thank you John let the odyssey continue this is so much fun

Thank you for this. Mulvaney and Khan are true scientists who are not afraid to rock the boat. At a conference I ran, a soil scientist discussed reading Khan's potassium research and was astounded by it. He expected heavy pushback from the industry. I have 40 years of cropping experience. So much of my knowledge was wrong but this is the same in any field of research.

my goodness, lessons of a hundred years in a little over an hour. what a delight and not in small part that Dr. Richard Mulvaney is delighted with his learning and sharing...blessings to all

[@mildhug9645]

Thank you, Mr. Richard for such a huge bunch of useful information! Thanks, John for inviting Mr. Richard!

John out here KILLIN IT

[@TheFarmacySeedsNetwork]

Wow.. very interesting conversation as always. Amazing how potassium is so versaltile in the soil, in the plant and on the soil surface! Thanks John!

[@peterparkerlovesmj]

Amazing podcast. Thank you, both. John, please update your audio equipment haha

After a 100 years of cropping abuse, I am surprised that there are any N non responsive sites. Must be great soil and good stewards.

[@tradcon3096]

Does non-responsive mean no Isotopic uptake from the synthetic N, or no yield response? Maybe he said but I couldn’t find that???

[@traymiser]

I enjoy all the information from AEA but I especially enjoyed this one!

[@robmiller2919]

Does tillage have any effect on this?

[@Forester-qs5mf]

Is K humate any better than the other forms?

[@Dakindbrew]

Grow onwards & upwards good sirz

[@joseluizm.garcia998]

Well done

[@donready119]

Dave Brandt is getting 200 bu corn with 50 lb of synthetic N using notill and cover crops. There is your 0.5lb per bu.

Imagine if doctors could revisit germ theroy.

Now this ☝🏽 would rock the proverbial boat....

[@mauricecalliss1303]

Potassium increases from the rizofagh exudates. as we all now come to understand.

[@mauricecalliss1303]

Sounds like the plants are using potassium for many things one of those being to clean and flush its system amongst other things .

[@mauricecalliss1303]

Or there's a case of bio transmutation of the clay calcium content into potassium ???????? Controvercial
