The audio transitions are jarring. Otherwise, great video.

Great video

Cant believe the soil in this video. We are solid clay. I can dig down 15 feet with an excavator and it is just more solid clay....

What percentage of chemical fertilizer is absorbed with conventional foilar spray ? Do we need nano fertilizers for foilar spray ?

watching here

Not many rocks in that beautiful layer cake soil; wonderful talk 👍

Just watched "Twenty Years of Vertical Tillage" if you want to understand why you and how to till your soil and why plants do what they do and how compact soil stresses them and makes them turn until they find a fracture and hurt bushels/'acre. This video and That video are well worth watching and watching until you understand everything they are saying. The first video is from the guy who thought of vertical tilling. How many guys dig 14 feet down into the soil to follow root growth? Fascinating knowledge as a result.

No Till is fine for a few years as far as this teaching goes but after a few years of not opening your soils deeper soils will compact over time and not allow the moisture to penetrate deeply. What are the average of years a farmer can go with NoTill before they should cultivate deeply and open up the soil again and Rejuvenate and bring the deeper soils up and turn your soils over?

🙏🙏🙏🙏

Very good video and explanation. :)

tilling is not good

this is wrong, agricultural land covers around 50 million sq km. or around 10% of the world's surface.

Keep an eye on who owns most of the farmland, they will control your life one day.

Alfalfa in the rotation? What rotation?

Great information!

Please place the camera on the other side so I can see your face instead of you back .

Thank you

Excellent mechanism 1st in series about soil compaction

great video very informative and full of proofs, this is what i was looking for, thanks!

WHAT size nozzle does a county worker use? What size droplets ? There's drift along side lakes evident in Browning of grass and death of trees nearby

Disagree with the plow comments. If the soil is plowed but not compacted in the spring, residue will break down

Thank you so much! For the lecturer for the excellent presentation and for the clever mind who decided to capture and spread this precious information! ;-) More and more I get confirmation. That on my small "no till" farm, the old tiny tractor 🚜 I've chosen was the perfect option! :-) Save on cost (acquisition and maintenance), save diesel, save hours of work. save the soil, etc. On the other hand even for such a small tractor, I'm still trying to figure out the best paths/roads. Precisely to avoid soil compaction and also avoid criss cross the 3 different levels of the property with tire tracks...

No till is solution

This is fantastic! I wish it had more views. Anyone and everyone in agriculture should see this.

May I foliar feed at night

:)

14:45 is where they actually talk about shallow tillage.

I'm from N.S. W. Australia. Wow this is the best lecture on this that on this subject that l have heard. We were in self mulching black basltic soils through to sand. We couldn't work out why even sunflowers could get vertical roots because at four inches every root went side ways would stop growing down and only go a short distance even wheat and sorghum would do this. And it would short yellow and spindley on another far it was far worse than this even clovers and Lucerne would only be stunted and yellow and stripey but after deep ripping in a drought(!done to controll severe nut grass infestation twice with Secord working being a 45deg cross rip for the next ten years there was none of these problems or desease issues that had been plaguing us. J had the tractor tyres running on radials set on 16lbs psi there was slippage and so on.

thank you so much for these great videos!

Load bearing capacity of air depends on atmosperic pressure, but the range we have in the atmosphere naturally is very low even at the highest pressure level. Think of a boat... it floats on water, but not in the air.

I want that "plant prairie" poster! Can I have it when it gets old?

Not a farmer myself, I'm a dedicated gardener, but if I was growing corn or other crops she has demonstrated excellent points. I turn my soil by hand between every year we plant. I understand air content, moisture retention as well as drainage, along with nutrients needed for certain plants such as tomatoes & peppers to prevent end rot. It's been a learning curve and you only get 1 time a year to make any changes. Our garden is very high yeild and low on desease, except for a root worm problem I thought I had solved using damascus soil, but it turned out to be a failure as I had to pull all our raddishes early after seeing brown leaves/signs of plant distress. Root worms were of course the cause of that distress, and still figuring out a way to kill/get rid of them without using any chemicals. My take away from this is the compaction aspect of it. I have tri-mix soil and obviously don't run heavy equiptment over my garden, that being said, I see the importance of trying to maintain a very none compacted surface. I'll have to be mixing in some pete moss at the end of this grow year as my soil is starting to get compacted.

Dear Sir, I liked your demonstration, can you answer my question please, As per my understanding the air induction nozzles have clogging problem during field operation, there is any solution for that problem. And secondly for very large droplets the runoff could be a big problem which will contribute the runoff and cause soil and ground water contamination.

What an excellent video demonstration.

Wow that was an impressive presentation and very informative. Somebody sure knows their business!

Love it .. Very good.. I feel like i am back in High School FFA.. Now at 50 learning it all over again..

One of the comments struck home.." No one knew how to set the plow" Is it so bad that plowed residue is slower to break down? To me that seems like a good thing as it is a sign that the residue is not being converted rapidly into carbon dioxide and global warming. Much of the criticism of the moldboard comes as a result of not knowing how to use it, how to set it, how to maintain it, when to use the plow, when not to use it. Correct soil management using a moldboard plow is much less damaging than disc rippers and chisel plows. The ripper style tools totally annihilate soil structure completely disintegrating the fungal environment whereas a properly set, properly used moldboard will cut and turn a slice of soil and does not completely annihilate the biological environment. On the subject of plow pan there has to be a distinction made between a change in soil density and a plow pan. A change in density is created by a plow but a plow pan is created by over inflated tires in the furrow bottom, plowing at the same depth year after year, a poorly adjusted plow, worn out ground engaging parts. Soil doesn't mind the appropriate use of a moldboard plow in the rotation - how do we know this? Yields and profits increase. The moldboard plow is not an environmental and soil health problem. The misuse of the plow is the real culprit. best regards Jim

Did you do this with soybean PREs as well?

You have made many good points. But in some instances not plowing can cost money. We run a disc ripper every other year and other tillage practices on no till. But if we have to go corn on corn plowing the cornstalks will gain 15 bushels and we have friends that have found the same response.

great vid ms Jodi! your knowledge is awesome :)

You are asking great questions. Soil compaction is not an exact science. There are too many factors that contribute to soil compaction to accurately predict depth of compaction. These include: soil texture, soil moisture, organic matter content, restrictive layers, soil structure, tire/track psi, axle load ... However, when it comes to factors we can control, we look to tire psi and axle load. The heavier the load the deeper the compaction. The higher the psi the more intense the compaction. There is research out of Ohio State University that shows psi also affects the depth (as well as the intensity). Research has also shown compaction down to a depth of four feet, but more commonly down to 2-3'.

Great videos! Thank you! I have a few closely tied questions: Why does the compaction depth not change with ground pressure? I understand from watching your videos that with lower ground pressure compaction intensity will decrease at all depths but the compaction will still go equally deep into the soil. Is that correct? If the above is true, what determines the compaction layer depth that a tractor leaves behind? How is it related to intensity and depth? I look forward to your reply. Thank you for your time.
