Ultra High Density Grazing Cover Crops - April 19, 2024

- Last spring I went to Greg Judy's (@gregjudyregenerativerancher) annual grazing school with Ian Mitchell-Innes.
They talked about the magic of ultra high density grazing and how it can totally revitalize farms within a few years. They showed two days worth of pictures, videos, and on farm examples of how this grazing method can exponentially improve soil health. I was completely sold on the value of grazing like this on perennial pasture, but over the past year I began to wonder… could ultra high density grazing have a similar impact on row crop fields?
Today, we are trying to answer that question with a grazing experiment on one of our farms. Our goal is to determine if ultra high density grazing is any more beneficial than the rotational grazing we normally do.
To be more specific we will be grazing a diverse, high biomass cover crop with a mixed herd of cows and calves. This specific herd weighs 27,500 pounds and our goal is to graze at 500,000 and 1,000,000 pounds per acre.
In a few weeks, we will plant the farm in corn. The crop will be maintained like normal throughout the summer. Then in the fall, we will harvest the corn with a yield monitor.
Best case scenario: We'll see a dark green strip where our experiment was on the yield monitor.
Worst case scenario: We'll see a strip of weeds growing this summer because the corn failed to come up.
No matter the outcome, we will soon know what a million pounds per acre looks like, and how that much herd effect changes the soil for better or worse…

best video we've seen on the subject
Thank you so much!
Nice looking cows and calves
Good video. Thanks! 👍
This is the best explained video on this subject . Many thanks.
I really appreciate that! Thank you!
Excellent video! As honest as it gets. Please keep sharing.
Thank you! The learning curve feels pretty steep sometimes. It’s great to learn from each other!
Great video. The process is just so labor intensive.
Thank you! Yes, it was a lot of work. If we were going to do this long term, we’d have to have a better fence and water set up.
Yes but you will get a higher return and you will actually massively improve your soil which is critical.
Soil health is so important but we are realizing that we have to keep animal performance and quality of life in the equation too. We’re very interested in finding techniques that maximize the impact of our efforts. I’m not sure we have enough cattle or pasture land to justify high density grazing all the time.
Well done. I do wonder about the long term health for cattle with so little roaming area. I would imagine Greg Judy or Joel Salatin would be able to address those concerns.
Thank you! They would definitely know! I don’t want to speak for them, but as long as the cattle are well fed, watered, and calm, I would expect them to thrive with fast rotations, even at high densities.
Love the video. Really appreciate the in depth analysis. Great mix. May i make a couple of suggestions from my experience? First, if you're just taking the top xxx inches you can start grazing much earlier (before everything matures) and move on. Second, if you widened the paddock so everyone could line up like they were at a feedbunk (likely about 2' per COW - not a yearling) then you could strip graze and the trample effect would be less AND, given the rapid moves, your forage would pretty much spring right back up within a day or so. Then it keeps growing, getting those roots down into the soil just as though you had allowed the plant to mature fully. We've also used tumblewheels to move along what really are alleys that we strip graze. We moved five times a day and it took about five minutes per move. Now, there are other technologies that can lift a wire, open gates (love bat latches), etc that can make the whole thing so much easier, Even basically automatic. Don't weaken! You're doing so great! Keep looking for solutions.
I really appreciate the suggestions and the encouragement! Pen shape was something we debated and eventually decided to keep it simple with a relatively square shape, but I would love to try the “feedbunk” style pen! Trying high densities at different maturities would be another great experiment. There’s so many things we still have to figure out. I hope we can implement these suggestions in the future! Thank you again!
Great visuals on this video. Keep up the great work thanks, learning heaps.
That’s so great to hear! I really appreciate the feedback!
Great video
Thank you!
Fantastic explanation, you put this video together very well. Thanks

That’s exciting! Let us know how it goes! I’m always looking for more info on this topic!
Good job
Thanks for video
Thank you and thanks for watching!
Can't wait to see the result!
Yes, us too! We’ll post updates along the way!
Best video
We do this and it works! Works amazing for soil health
I would love to know more! Do you have a preferred density? And how many acres do you try to graze each year?
Great job and explanation. I will be looking for some overhead views of that corn, throughout the year.
Thank you! We’re looking forward to that too! We’ll definitely keep you updated!
Great !
This is amazing! I can’t wait for the experiment results. Will there be a few acres unused? Will crop come back faster because of the manure density? So many questions. Great work
We’re glad you’re excited too! We have another video showing the results 24 days after grazing that might answer a few of your questions: czcams.com/video/UnziXZLPY-g/video.htmlsi=kGmpkFQFpetNqNzs
We’ll do additional updates after planting and harvest. Thank you for watching! Please let us know if you have more questions!
Need more such content, thanks
Thanks for watching! Is there anything specific you’d like to see?
@@GiffinFarms well we do exactly that but just at a much larger scale, I just like people showing that stuff like that on CZcams.
That’s awesome! Do you graze perennial pasture or crop ground?
@@GiffinFarms mostly pastures. We use Gallagher geared reels with step in posts
@@daronstahl351 very good! We like the Gallagher reels too.
Awesome video. Have you looked into automatic gate openers (or Batt Latches), fence lifters, tumble wheel fence movers, or virtual fencing? I think if you had these tools, you might be able to continue to use ultra high stock density grazing with a lot less work.
Thank you! We have a few tumble wheels we like to use with strip grazing. They definitely help with time and labor. I agree, batt latches would be super useful in this situation. Virtual fencing would be the dream, but I’m not sure how cost effective it is yet. If we continue grazing at ultra high densities, we’ll need to spend more time on fence and water infrastructure. I really appreciate the recommendations!

Thank you for watching!
Great video. I have focused on pastures pigs the last couple years on cover crops as my videos suggest. I have recently been strip grazing a cover crop of clovers, rye grass, vetch, chicory, and rye. While watching them graze I considered a temporary test of several hundred thousand pounds per acre to see what happens.
Thank you! I’ve enjoyed watching your videos! I think pigs must be one of the most challenging animals to graze, but you make it look easy. I would love to see a test like that!
@@GiffinFarms sorry I did not clarify. Ive been strip grazing that with crop mentioned with steers and considered increasing the paddock size to see how differently they graze and trample the crop. I’m not sure that I have the stamina to do it with pigs. They are a bit devilish!
By the way, your visuals and editing was outstanding. It really helped demonstrate what you were talking about.
@@DowdleFamilyFarms Thank you, I really appreciate that! I'd love to know your results if you decide to run your experiment!
After watching your video, I think your cattle are well raised. Our company produces solid-liquid separators that can convert animal manure into fertilizer for crop fertilization. If you use fertilizer for grassland maintenance, you can achieve maximum resource utilization. We hope you will carefully consider our suggestion.😄
Who sells solid liquid separators. Is it pretty tough "feeding solids/liquid into separater.??
Yes cowgirl .... May the Lord bless you ....
Thank you! Same to you!
Awesome how-to video! Hey, I'm a SoilFoodWeb school graduate, where I learned that soaking cow feed with compost extract allows the cows to spread the beneficial microbes throughout your land. Know that properly made compost complies with food grade temperature & time requirements, whereby the bad bugs and weed seeds die off while keeping the beneficial organisms. Also, biologically complete compost will have sufficient ratios of 5 levels of biology, from bacteria and fungi at the smallest size to beneficial nematodes and arthropods at the largest microscopic size. Also, I'm a student of the Crescive Method, where we balance soil minerals using organic amendments like gypsum, oyster shell, feather meal, green sand, etc. It's based on the Ideal Soil V2 and you just do it once, then periodic monitoring to tweak the levels. Each 2 cup basic soil analysis goes for about $24 at Logan Labs. The interpretation of the report is mostly based on the Ideal Soil book. Combine these 2 methods for excellent benefits, according to my studies. My lawn does look great, that's the extent of my practice. I plan to buy a few acres soon where I will use your video tips too.
Hi .could we work together please?
@@wadmaileykeemhanjoseph8913 I'm happy to share my knowlege. But I don' t really practice it except around my house. I need to buy some land. Also, I'm short on time, so, I only do this for fun.
Yes, I understand you.l am working on a project i will let you know!
Экстрактом какого компоста нужна замачивать карма?
@@Spantamano-tg7tn Biologically complete compost that is prepared using either the thermocomposting method or the Johnson-Su method. It is considered biologically complete when it has sufficient ratios of the 5 levels of microscopic microbes. Look up Dr. Elaine’s Soil Food Web Approach or the Crescive Method for more resources.
I working on several comments..some getting lost in the airwaves..
Nice video! Looking forward to following y'all's journey. Did you plant these cover crops late last summer/early fall?
Thank you! On this farm, we harvested corn on September 19 and drilled the cover crop on September 24. This was the first time we grazed this field. We have a few other videos of grazing cover in March and early April if you are interested. It grows crazy fast this time of year!
@@GiffinFarms Thank you! The field looks great and your cows are happy.
Daily move or multiple moves per day.
Cattle are content, a good sign.
Great Video. How many moves a day did you do, or how long on each grazing cell?
This small scale experiment only included four pens, three at 500,000 lbs per acre and one at 1,000,000 lbs per acre. If we were going to graze at 500,000 pounds per acre all day, I think we would move the herd about every 45 minutes or 12-15 times during the daylight hours. Of course every field and every herd would require different timing.
If that's too much work what else do you have to do that Day.
If you have the time for it setting up the system so that you move them about 2 times a day is probably the best in terms of time invested and results you get
I totally agree! Daily moves are far more practical over the long term.
Probably I need/to use my scope and determine whether beneficial microorganisms are in my soil. Who is author of the Soil Book. Probably available here in ks.
It been proven that if you want to trample more make the paddock rectangular shaped instead of square shaped. Also don’t forget to move th water too.
Water is a challenge! It would be cool to try different pen shapes in the future.
Your cows look exceptional. I'm still not sure how you guys can make enough? Here on the Eastern Shore taxes are crazy.
Thank you! Taxes are no fun!
Would definetly need to work on the farm full time to do this effectively right? I always thought of doing this, concentrate all the body's in 1 small area but wouldn't be able to leave them long in that area..
Yes, most likely. There are a few automatic gate openers (batt latch, pensagro, teeter farm tech) that could move the cows on a set schedule, but they are pretty expensive for a small herd. Fewer moves at a lower density may be more practical.
In Switzerland they developed a virtual fencing system where each cow has a device around its neck that gives first an acoustic signal at a standoff distance and then an electric shock when the actual (virtual) fence line is reached. This would enable any grazing scheme without much effort.
That does sound awesome! We would be all for that if we could find a cost effective way of accessing the technology.
@@GiffinFarmsIt is yet to be approved by the authorities, but if it goes through in Switzerland I guess it will in every country.
Not sure where you are located, but I think there are a few companies in the US that are approved and functioning. Vence is one that I’ve heard of.
@@GiffinFarms I‘m located in Europe. Makes totally sense that it is already established in the USA, way bigger market and probably less bureaucratic hurdles.
That could very well be. I would love to try some in the future. I hope it’s accessible over there soon!
having the math broke down made the video one of the most informative i've seen. could you add a few more cattle, and increase the pasture size a bit more to make it a once a day move so its easier on the labor side of things? most of the AMP (aggressive multi paddock) grazers say 12 hour moves or 24 hour moves.
I’m glad it was helpful! You could definitely add more cattle and make the pen bigger, but high densities will always require many moves per day. For us, this only works in special circumstances. Normally, daily moves work better for us. In my experience, daily moves are still great for animal performance and soil health.
Certainly...paddocks are all unequal as/in not the same
quantity of forage in each. Writing a program explaining all the various factors of rotational grazing would be impossible. Thanks for your explanation and photography. Dennis
You may already be familiar with Greg Judy’s CZcams channel, but I highly his videos and grazing school. He shares a lot of information about all the different factors you can run into while grazing.
#naturalgramma
How did u get electric fencing through there. The grass is that tall it would short out?
That is a great question! The cover crop does weaken the current and completely short it out at times, but as long as it has some current most of the time and we keep the herd well fed, they respect the wire. In fact, our fence wasn’t turned on at all that day.
Hello dear .how are you.? I am Naeem from Pakistan
.please inform Me about road grass.
So far scheduling the entire process. ..l have better idea now..HOWEVER have to decide when to plant 2024 spring rye cover cause i do not want to lose another cash crop to wait again to plant cover in fall 2024 for 2025 crop.. might plant a spring cover (rye or oats?) now or else plow, disc or harrow and plant soonest and cultivate as necessary.Dennis
I don’t have any experience planting spring cover crops. I’m not sure how quickly they would mature. Are you against chemical termination?
Look up Rick Clark for how he handles his 5k acres selling grain to the granola companies with no inputs no till. I have been copying his farming style at my place. You plant your corn/beans with a no-till planter direct into the standing rye. When the corn/beans emerge and before V1 you then roller crimp (or if you only have an old cultipacker then go "down and back" as that two-pass method will flatten the rye as good as a crimper), the corn/beans stand back up and with mulch below them and a long head start on weeds they shade out weeds the rest of the season, then you roll in with the harvester in the fall.
Rick Clark has some really cool stuff going on! Thanks for the information!
Define or send pix/of v1 stage of beans please.corn milo or wheat and anything else applicable as cash crop....possibly beans.... .I in KS. Summerr.....Dennis Wanna plant rye cover/at correct/season in KS/and plant soybeans appropriately and crimp rye cover appropriately and har est soybeans around or before frost. Dennis
I understand the part about no till planting beans/in standing/ rye.and/part about crimping beans BUT at what heighth.... apparently before they emerge...Dennis
@@denniskemnitz1381 We have successfully crimped beans anytime from immediately after planting all the way up to V1 when you see the 1st trifoliate leaf. But for corn, we always crimp as soon as possible after planting to keep from disturbing the emerging seeds. Corn seems to be more sensitive to crimping.
What does " roll in with the harvestor in fall" mean?? Thank you for info. I purchased 16'/crimper/2 years BUT have been/unsuccessful getting into the process. Possibly attempt next season. Dennis
When you were doing 500,000 lbs, was each pen move duration 45min? If so how many moves a day would that be? If you wanted to move a maximum of 4 moves a day, what would that look like?
Yes, our moves were about 45 minutes at 500,000 lbs. If we were going to continue grazing this way, I think we would have 12-15 moves during the day before letting them rest at night.
That being said, I think 4 moves per day would be a great place to start if the plan was to do high density grazing every day. If I want to do the math for number of moves instead of density, I would start by determining how much space the herd will need per day, divide that by 4 pens, and solve for pen size using the same equation as before. In this situation, I would start with 0.75 acres / 4 moves = 0.1875 acres x 43,560 = 8,168 sq ft / 50 ft = cross fence every 163 ft. Of course, we would be ready to adjust the pen size if the cattle seemed hungry or were having too little impact.
Keep in mind, you would need to give them more room overnight, either with a larger pen on the 4th move or by pulling your back fences and giving them the whole day’s worth of pens to rest in. In our situation, 4 moves would achieve a density of nearly 150,000 pounds per acre, which is still awesome.
Thank you for the questions! If you try it, we would love to hear how it goes!
One thing that you could do to cut down on some of the labor is to not worry about a back fence. I practice managed grazing from May until the first of December or so. It’s been my experience that the as long as the cattle are getting fresh grass on the regular, they don’t worry about grazing the trampled soiled grass until the new growth starts. Usually about 3-5 days after grazing. Great video!
@@jamesobryan3258 Thank you! That is a great point! I agree, no back fence would save some time.
Is there possibility of one or two moves daily. Too many daily moves it seems to do other farming jobs. Dennis
@@denniskemnitz1381 We prefer daily moves for our normal grazing rotations. The cattle stay full and healthy, the soil gets the rest it needs, and the work life balance is better for us!
You need more calves in the springs sell them when you run out of cover crops. But this means lots of $$$ Capitol . If you had the $$$ automatic fence openers and closers would be the way to go when you can afford it
Lots of capital and lots of market risk! Before we find more calves, we want to fine tune our grazing method. A few automatic gate openers would be awesome!
What is the mix of the cover crop please
Triticale 20 lbs
Cereal Rye 20 lbs
Black Oats 15 lbs
Austrian Winter Peas 15 lbs
Crimson Clover 8 lbs
Hairy Vetch 4 lbs
Balansa Clover 2 lbs
Rapeseed 1 lb
Purple Top Turnip 1 lb
Fall planting i suppose. Dennis
@@denniskemnitz1381 Yes, drilled in late September
How long were you leaving them in each paddock at 500000lbs?
About 45 minutes. They were too full to start with so we left them in the first pen longer to help them make some room in their gut.
He lo bạn chào buổi sáng tốt lành❤️🔥❤️🔥❤️🔥❤️🔥❤️🔥
So just ran across this.
It is hard to figure out. What exactly you are trying to make a difference in? If it is soil microbes. You would need a baseline. Then sequential testing. From the video the cover crop looks fine. But did you measure it?
This is my thing about rotational grazing. And its claims of the grass recovers quicker or is more organic matter.
If I cut the grass on my lawn. It is bahai grass. That stuff comes right the hell back. Comes back so high. I have to cut it every two weeks.
As far as organic matter. That also would have to be done in sequential order.
As it will vary. Say before or after a rain. This is the first video I watched. It is well done. Especially with the graphics.
But seriously grass in season. Comes back pretty fast after it is cut.
So many variables in this stuff. It is easy to get caught up with antidotal evidence. And believe correlation is causation.
I really appreciate your feedback and I agree with everything you said! I would like to add a few points to consider.
First, grazing is differently than mowing because animals eat their favorite plants first and leave the undesirable plants. if there is no rotation, the best plants are eaten over and over until they eventually die and you’ll be left with only undesirable plants. If animals grazed like a lawnmower, taking every plant to the same height, rotations and rest period wouldn’t be so important.
And excellent point about all the variables! Honestly, those variables make it impossible to do a perfect on-farm experiment. But I hope an imperfect experiment is better than no experiment at all, as long as the goal is just to better understand our environment and our goals. Specifically we would like identify which type of grazing is best for increasing soil respiration rate and organic matter on row crop ground, and decreasing the risk of nitrogen tie up for the next crop.
We are measuring these things with cover crop and soil samples (taken this week) so we can compare each type of grazing. We have soil tests from last year, but I agree there are too many variables for year to year comparisons to be super useful. We’ll be sharing our most recent test results soon!
Thank you again for the feedback!
@@GiffinFarms
Well it wasn't clear what your goal was. It looked like a planted field of cover crop. Which the animals would eat all varieties of.
But I was begging to think you where using the cattle for trampling the grass instead of crimping it. Then come back later and plant into it.
It just wasn't clear what your goals where.
The soil samples I'm sure are nothing new to you. But is microbiap activity one of your goals to measure?
Your ground already looks healthy. Do you know otherwise?
Still thought it was worth watching. And went ahead and subscribed. To see what you do next.
We all are learning from each other. Cheers!!
@@MrSeadawg123 I do wish I had defined our goals for this experiment more clearly. Our farms have decent soil, but we would like to increase natural fertility so we can decrease inputs overtime. We are definitely still learning! We appreciate you watching!
@@GiffinFarms
In my eyes. A person has to be pretty fearless to put themselves out on YT. And accept the feedback given.
Appreciate your thoughtful reply!
And will try to contribute. On topics I have some knowledge in!
One of things I will be trying. Is mixing biochar in with molassess barrels. To put more carbon in the soil.
We have a farmer that manages our farm in western Kansas. Very dry there. 10 to 20 inches of moisture a year.
So am trying think of ways to hold what little moisture we have. In the ground.
Have a 100 acres here in Alabama. That land needs to be cleared. So will be awhile. Before I have animals on this land.
Wishing you best of luck!
Look forward to watching how you manage things!!
🍻
We appreciate your thoughtful questions and comments! Keep them coming!
Kashif Gill Pakistan I love you ❤❤
What do you do at night
I don’t have any first hand experience with multiple days of grazing like this, but Ian Mitchell Inness suggested giving them a “whole days worth” of area to spend the night in. You could pull up your back fences in the evening (or don’t use back fences at all) to give them access to the whole pen. He also mentioned penning them in a specific area that needs a lot of help because they will add a lot of fertility with all the overnight trample, urine, and manure.
With that grass that tall how many eye problems do you have ?
Knock on wood, we haven’t had too many eye problems in tall cover crop. I think it helps that the seed is well above their head while grazing and we pull the cattle off before the seed is mature. We have more problems when our fescue pasture gets too mature. If you have any solutions for that, please let us know!
Beasts looking healthy n fat tats all matters 😊😊
50 acres are 21 hektar
This is jersey cow?
Our cows are mostly black and red angus, plus a few with charolais influence.
I send you jersey/cow pic; just request. Dennis
Get you some hogs to follow the pigs root the geound and doodoo. Get you some chickens to follow the hogs. Scratch the ground and doodoo.
That’s a cool idea! We have a few hogs but we don’t have any experience keeping them behind a hot wire. Do you think they would tear up the ground too much for crops to be planted soon after?
My question would be why did you let it get so big? It would have been a lot more beneficial to the cattle if it wasn’t as mature. From what I saw they wasted a lot of it by knocking it down and trampling it.
We didn’t really mean to let it get that big, that’s just what cover crop does here. We started grazing when it was 6-8 inches tall in mid February, but it quickly outruns our herd. I also thought it would be interesting to know how much they would eat vs trample at that maturity. Maybe in the future we can try again when it’s not as mature! Either way, the trampled forage will make great worm food!
I’m from south east Kansas, we’re just coming out of 2-year drought that’s part of why I commented I guess. We’re generally too dry in the fall for cover crops although once in a while we get some fall rains. I used to crop farm but haven’t for about 15 years now, just have cow calf operation. Thanks for the video though.
@@HankJr213 We appreciate the questions! We are definitely in different environments. I can totally understand why utilization is a priority for you in a drought situation. I hope y’all get more rain soon!
We have! Almost 8” in last 3 weeks, creeks and river were out of their banks and took out some fences, water-gaps etc.
When it rains, it pours... maybe it will even out soon!
It's a great idea... until it isn't.
But why wouldn’t you run with it as long as it is a good idea? If it begins to stall out on you, you make a change. Adapt and overcome.
@user-fp7uh9jx8n - unless you have a micro-herd of just a few head (less than 10) you're gonna end up doctoring for pinkeye all from late spring to early fall.
Couldn’t have said it better. No matter how good the idea is, there will be challenges to overcome.
@@driverjamescopeland pink eye is a practical thing to be concerned about. Unfortunately I think pink eye will always be a concern where we are. One good thing about having them grouped together and moving is we are always moving away from the fly larvae in the manure piles. It’s also nice to see them multiple times a day because we can catch any illness early.
Sorry but 40 pear is 80 head
Sorry but 40 PAIR is 80 head only part of the year. If you want to get very technical you could try to predict the average weight of your calves and add that on a pro rata basis to your total carrying capacity. In my experience, this is only beneficial if you are going to use total carrying capacity to compare your production model to others, like cow-calf production to stockers or some mix of the two. You can make the math as complicated as you want but at the end of the day, if your farm supports 40 pairs, you can run 40 cows.
