Best soil professor ever

Amazing knowledge. Can’t wait to venture over to middlefield to pick up products.

John Kempf videos are outstanding. one observation though, wish there are not so many audio pauses

Beautiful. Thank you!

I've only watched segments of this talk but enjoyed what I did hear. I'll be watching this one again in full soon. Thanks for the upload.

thank you, good presentation

Really awesome! Keep it coming...

At 25 minutes: we have seen the drop in sap mineral concentrations in dicots (soybeans) in lower leaves consistently following a spike in sugar production. We produced the spike by doing a foliar application of Magnesium chloride in combination with a broad spectrum of trace minerals from multiple sources of chelation technology some more effective than others for certain of the traces which you have experienced with manganese. In contrast, using the same foliar material to produce the spike in sugar production in grasses, we have not seen the reduction in sap mineral content in either upper or lower leaves. In fact we, without exception, see P increase in plant sap. We speculate that the microbiome uses the additional energy to mine more effectively for P. This of course continues to fire prolonged production of ATP for making more sugar. We see the calcium level in sap increase too which is necessary to have with the P in the mitochondria to make ATP. My understanding is that the movement of minerals in dicots verses monocots is very different. For this reason when we apply foliar nutrition to dicots we make every effort to avoid applying nutrition to the top of the plant. As a sidebar comment, the alternative approach or standard practice has clearly shown us that cannibalization of the mid-plant and lower fruit set takes place. There is a challenge created by applying nutrition to the top of a monocot which calls for more mineral nutritional support and the plant responds by translocating minerals from lower plant parts thereby aborting fruit. Monocots will not move minerals downward to earlier fruiting locations like monocots do either. So we build yield on soybeans, for example, by applying foliar materials under the canopy.

James Martindale Sir are you some kind of Scientist?

Thank you .....

Yay,.too many introductions. Topic starts at 12:01mins.

good stuff

Balance over quantitiy!

At 39 minutes: I have found in working with minimal disturbance vertical non-inverting tillage which creates efficient water and air exchange in soil, predating the introduction of CurseBuster tillage by more than two decades, that the biggest obstacle to creating a beneficial fungal soil is no-tillage and conventional tillage. Note "beneficial" in that statement. No-Tillage creates a fungal soil but it is pathogenic because the water and air exchange is poor featuring prolonged periods of wet, cold soils in the springtime.

James Martindale if you’ve seen any no till farmer worth his shit you’d realize that there’s enough air in the soil. Like Gabe brown.

have you any examples or online links to implements that allow for 'minimal disturbance vertical non-inverting tillage' am very interested in what you say as it makes sense to me

Samanda thank you.

I had been adding seaweed to my pasture, but is it easier to just feed it to my cows than chop it and spread it?

A worm bin might be useful in this case although I don't see the harm, just not a normal food source for the cows

at 35 minutes: Talking about the minerals which are pivotal to maximized sugar production; I only counted 4 (Mag, Fe, Mn, and P) in your list unless you planned on the brief mention of Nitrogen to count as one of the five. You go on to make clear implication of the effects of glyphosate. I'm relatively certain that you are referring to soil residues of the original salt plus AMPA. I would like to suggest that foliar applications of glyphosate in our "normal" precipitation is also a significant interference. In this regard, according to a study of stability constants for glyphosate, Iron is more reactive than Mn. Even copper is more reactive than Mn. It no wonder that plant ability to mount a defense against fungal invasions is very poor generally. The other thing contained in our precip today is nano-particle Aluminum. Do you have any comments on the impact of high levels of aluminum circulating in plant sap?

Non-bonded (synthesised) Aluminium is toxic to living organisms, especially in nano-participle form. Monsanto has been making their GM crops aluminium-resistant for years (probably so they can continue to sell aluminium-based fertilisers, pesticides etc

Can someone please point me to a good source for soil nutrient balance?

Look up Build a Soil. There in Colorado! Exelnt Soil and amendments. Good luck

I'm about to start farming with the principles of regenerative agriculture, I plan to sow a cover crop mix of clover, bermuda grass, dichondra and a couple of annual grains. however I'm not quite sure if the grass is a good idea for building soil. any thoughts?

Some very serious mistakes in this. Sugars in plants are made only by photosynthesis. They are not made in the root, or the meristematic stems of the plumule or radicle. All sugar is produced by the photosynthesising plant "biomass" and then distributed to the other parts of the plant. There are sugars in those other parts, yes, but they were transported there from the green parts. When a seedling emerges, it is burning off sugars in cellular respiration, not producing sugars.

Yes, later on in the video, you say it correctly.
