Very few university fertility researchers believe that foliar feeding works. Yet all yield winners and high yield achievers depend on foliar applications to supply needed plant nutrients. When quizzed about the work done in Univ trials their grad students who actually do the work are ignorant about which products, practices, day timings, plant growth stage timings, water quality, pH of the spray timings, pH adjustors, chelating agents used in the foliar materials, EC and exact ECs of the materials being sprayed. Other things apply. Once you begin to read about the contest winners and find out what procedures and products they are using, you are partly home, because what have learned does not include what those secrets those individuals don't reveal. They all have their secrets that they have honed thru practice and making their errors. Again another concept that needs to be learned is that with foliar nutrition, soybean plants especially, foliar applications are used to manipulate plant architecture and physiology. Those two items alone can help a grower steer their plants along a path that can produce maximum yield. Thus one has to ask which researcher jumped to those conclusions that tissue testing was not valuable. Did any of them personally walk the fields of Ray Rawson, Kip Cullers, Francis Childs, Jimmy Fredricks, and so on to learn how best to succeed? Did they study and read what was taught by HB Tukey and Patrick Brown? If they did not what they all learned was how to fail. Each grower has to learn from an interested grower who has succeeded in their quest to use tissue testing to help option high yields and not someone who has failed. Students of crop raising need to learn from winners, not losers. Today's farmers who expect to stay in business know they have to learn so much and that learning never stops. Now the lowest stave of the barrel theory still applies. You have to start somewhere when you design your fertility program. First on the list is a good soil sampling program where the analyses include the macro minerals, the mid minerals, and a number of the micronutrients. Next is in-season tissue testing, because a grower has to keep tabs on the mineral status within the plant, and be prepared to address any and all deficiencies. There are plenty of labs that can perform these. Tissue testing is like the pilot of the airliner you are flying in is expected to be observant of the planes gauge's constantly. Tissue testing and the analytical results. Looking into the future are advancements beyond tissue testing. Those I have worked with are sap analysis, of which there are a handful across the country that are accessible to all growers. Those are patterned after what two chemists/agronomist Soerdts and Jaon Timmerman from the Netherlands pioneered. Above and more immediate than tissue would be real time use of the X-Ray Defraction scanner. That machine is widely used could revolutionize soil fertility research since there is no wait to get results fast. It can be used as in the 1950s thru the 70s researchers more commonly used radioactive labeled fertilizers to track penetration and movement thru the plants.

Where can we find more information ‘Witte-Bio-Consult’?

John said to try Bokashi in 42:07. You can try KNF as well. There are many other sources of TE as long as they remain anaerobic/slightly anaerobic. I'm just trying to help you out as is my case in my country that I couldn't get AEA products at all. AEA product is absolutely different because is dry stable (Micronised minerals) whereas bokashi etc are not dry stable, so cannot be shipped. Anyway, john FTW.

Steven, do you have an answer to your chelated manganese question?

@@paulbraga4460 Not for foliar sprays, no. I ended up going the longer route of spreading a mixture of manganese sulfate with lots of calcium carbonate and some brown sugar near the end of the growing season, then growing a cover crop of hull less oats. I plan to do this every year now. The oats really seem to help the microbes thrive. Slow and steady wins the race I guess.

@@stevenhaver well, yes - slow and steady wins the race. if you have not tried JOHNSON-SU BIOREACTOR COMPOST, check dr. David C. Johnson youtube - results? - jump for iron and manganese - 1000%+. blessings

@@paulbraga4460 Awesome. Yes, I’ve been reading a lot about Johnson-Su reactors recently. It’s definitely on the road map, hopefully this year and if not definitely in the next year. Thanks.

Tilling and aerating soil, they need gas exchange, but not fresh oxygen. It also kills the top 12” of soil and turns it back into sand and clay with some dead material in it. Not a living 12” deep compost pile on top of your field. When the soil is alive it stays in balance. Run a blender through it and it’s just oxidizing dirt like a rusty piece of metal in a field

Hi KOFrass, thank you for your interest in starting a disucssion! Please send an email to hello@advancingecoag.com and include any relevant background information. - The AEA Team

Air can be a positive because of the N2, and it does not have the same degree of oxidation as oxygen gas.

@@JohnKempfVisionBuilderThank you for the response, which confirmed that air can be useful. I suppose my conjecture was that the Nitrogen was having a reducing effect. Tbh I am not looking at adding air in my current endeavours, but always find these concepts useful to digest.

I think you are mixing up the terminology and got it backwards. Basically, every molecule containing oxygen can be an oxidizing agent. Limestone (calcium carbonate, CaCO 3) can cause oxidation in the good old sense that the oxygen in CaCO3 can react with other elements to form an oxide. When Iron Fe2 reacts with oxygen, it becomes Fe2O3. Iron oxide. Oxygen is highly reactive. So when CaCO3 is said to be an oxidizing agent, it simply means it can let go of the oxygen and cause other elements to oxidate. It's actually an effective 'oxidizing agent'. The terminology can be confusing but Oxidizing used to mean when substances bonded with oxygen and formed an oxide. It later expanded to also meaning all oxygen like bonds, molecules with two parallel bonds. And thirdly, oxidizing can mean to be prone of stealing electrons, causing other elements to oxidize, in the sense that you were thinking of I believe.

The reducing effect of water in soil is largely due to saturation and the exclusion of free oxygen, and the shift in microbial community this produces.

@@JohnKempfVisionBuilder yes but can the wide range of oxygen carried by water, depending on its varying temperature, have any significant bearing on selections or otherwise of microbial communities. Does.this variance tally with the waters.own state of Redox ?

The range of pH would have a greater impact than temperature of the water.

@@HarrisonCountyStudio so are you saying water at 14centigrade pH6.0 is more reducing than water at 14c pH7.8? I know from consensus on reading that water carries less oxygen at higher temps i dont know how pH changes this. Its complex for sure

@@JohnKempfVisionBuilder ....your the best...your my inspiration...I am a Vampire from Transylvania...I will purchase a plot of desertic land in Spain...and I will apply Permaculture design in order to recover/regenerate the land...thank you ...thank you...thank you for all your free webinars...

They would make a salve from cow urine because it killed bacteria and the philosophers stone meant urine that was dehydrated then distilled until it formed a stone that was eternal life by the wayside

Good question... but I wonder if God commanded the Hebrews to observe the Sabbath year to combat this. After so much tillage the soil is too consistently damaged. 🤷🏿‍♀️

Have not looked at this recently. I don't recall.
