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.
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
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.
Usually tillage increases available oxygen and, therefore, encourages aerobic respiration that will burn organic matter more efficiently than anaerobically.

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

John out here KILLIN IT
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!
Does non-responsive mean no Isotopic uptake from the synthetic N, or no yield response? Maybe he said but I couldn’t find that???
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.
Is K humate any better than the other forms?
I enjoy all the information from AEA but I especially enjoyed this one!
Amazing podcast. Thank you, both. John, please update your audio equipment haha
Sounds like the plants are using potassium for many things one of those being to clean and flush its system amongst other things .
Does tillage have any effect on this?
Usually tillage increases available oxygen and, therefore, encourages aerobic respiration that will burn organic matter more efficiently than anaerobically.
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....
Potassium increases from the rizofagh exudates. as we all now come to understand.
Grow onwards & upwards good sirz
Well done
Or there's a case of bio transmutation of the clay calcium content into potassium ???????? Controvercial
