I live in SW KY... Have Bermuda in my yard and haaaaaaaaaaate it. Spreads way too aggressively and takes over the flower beds. Next season I'm going to raze the lot of it, so trying to nail down a good grass type and brand.
But it's been said in many vedios that iron, zinc uptake of plants will only happen in low pH. So if there is a high amount of phosphorus in soil all the iron and zinc will be consumed by reacting with phosphorus. So if we could maintain a high pH level phosphorus won't disturb the uptake of iron or zinc as per the explanation? Hoping for a response as I have some iron deficiency issue, which has a lot of different explanation on CZcams
Hey Karl. I typed in "Pure delight bentgrass" on google and didn't get a single result. Where specifically could one find this?
thx a lot I use this a lot for sleeping...
Me gusta mucho el Poa Annua 💚
Thanks for this information! I'm here because I'm reading Regenesis by George Monbiot and was looking for a picture. Pg 21 "Earthworms...excrete everything they can't absorb onto the surface of the soil, in the form of casts." "In...this orchard, earthworms can bring to the surface 40 tons of soil in every hectare every year."
Would Seashore Paspalum be suitable for shaded areas of a large residential backyard with a saltwater in-ground swimming pool nearby? Thanks.
I've tried this. My lawn is covered with weeds and it stopped my grass from going to seed. :-(
😂😂 the end is funny!
nice work, lots of heat with no rain, yall did great
Mr. Danneberger, I know this is old but perhaps you'll see it. I have a 1,200 square foot putting green that I built in my backyard. Sand based rootzone. I'm currently topdressing at roughly 100lbs per 1k every two weeks. It is slowly but surely removing the imperfections in the surface and my .135" HOC is very playable with stimp readings between 10-11. It's come to the point where, given I don't have substantial traffic on the green, I believe I can apply a heavier topdressing rate to alleviate some light thatch build up and firm the green even more than it is. My question is what is the rate of this application? I see things like 1-2 tons per green during aeration, but that doesn't help me. I simply don't know how heavy, heavy is. I'm using USGA spec kiln dried sand that is effectively identical to the rootzone. I buy it by the 50lb bag and have about 50 bags at the moment so I have plenty of sand.
I’m putting a putting green and in my backyard and using Tips grand I cannot wait to stick my nose in the air
Please can I get Paul number please
The obvious solution is to use Bermuda grass...
how much this hybrid bermuda grass cost? do you know the supplier or seller where I can buy this?
Love your videos. 😅 You’re so honest. 👍
😇 ᵖʳᵒᵐᵒˢᵐ
Hello Karl Im a home owner in the transition zone south jersey turf enthusiast Tahoma 31 this upcoming spring 23, doing topdress along with sand leveling always had a issue on where to get a good topdress mix can you point me in the direction 👍
Very strong looking dam wall around those huge tanks! Good planning.
Love to hear about St Louis putting you guys on
Fine fescue is such a nice looking grass for my state of PA. I just have issues keeping it green in sunny areas. But overall i love the look of it for a home lawn.
What an incredibly video. He never discussed anything of Interest. I guess he just wanted to see himself on CZcams. How incredibly stupid this video is.
I have established a new green on my farm. PLanted in August and it’s beautiful except for the earthworm castings are so bad the turf can’t quite close in. What can I do. Just wait for winter? They will be back in the spring.
That ending 😄
Thank you!
Thank you
So cultivars are basically a sub-set of varieties, right? It just depends on whether they evolved due to human interference or not. Is that it or am I missing a larger paradigm?
I'm writing a paper for school. You are the only person I have seen explain this clearly and comprehensively. Thank you!
Correction factor? I know what it means, but how is that applied on fertilizers excactly? Is it an estimate of soil type you're going to spread it on?
10 months late, it is the amount of Phosphorus in Phosphorus Oxide. Which means per 1lb of Phosphorus Oxide, there is 0.437 lbs of Phosphorus. Calculation is done by stoichiometry. Phosphorus Oxide is 142 lb/lbmol and Phosphorus is 31 lb/lbmol since there is 2 lbmol P in P2O5 you multiply that by 2. 142/62 = 0.437 This is important for researchers so they can calculate the appropriate amount of phosphorus needed for their fertilizers. Excess phosphorus can lead to oversaturation in the soil making it hard for other nutrient absorption, this can lead into stunting of plant growth. I'm sure there are more reasons (eutrophication like the one talked on this vid).
Karl, really useful vdeo-
Useless video for the most part.
Forward to 1.00 minute for the information.
Golfco Competition Rollers are the way to go! Best rollers in the industry!
Part of me wishes I had the time to even consider how stressed out my grass could or can be.
Is it the corn gluten itself that is controlling weeds or some level of glyphosate that has been uptaken from the soil the corn was grown in, residually there from previous crops that had been grown there? Meaning, glyphosate in the gluten even when glyphosate was not used directly for that particular crop of corn growth? Is it the glyphosate doing the killing? I suspect that the gluten allergy everyone has is really due to glyphosate in the gluten, not the gluten itself.
E85 we can run our vehicles off distilled fermented corn. But we eat it.
That’s scary asf to think about but you make a good point
Is your greenhouse insulated? Can I grow zoysia in the northern region in a greenhouse?
Hey thanks for showing what a 'worm cast' actually is. Garden channels mention these but don't show an example. Well, as a novice gardener, I thought it might be it's skin like a snake would shed. But now I know what those small piles of mud are, thank you.
Not your best is it …….
They need to protect their face with a mask or shield.
Excellent video. Thanks for the explanations.
Could I pull some plugs from my current turfgrass and run them through a chipper to make sprigs?
Déjà view.
Great video & history - we loved & shared it! This fall, we’ll release our 2 newest bentgrasses in conjunction with Dr. Stacy Bonos, Rutgers, & the USGA Green Section. They will be named Piper & Oakley in celebration of their achievements as agronomists in bent research, & for the 100-year Anniversary of the USGA Green Section! czcams.com/video/Df13mnlB03M/video.html
Can you explain what the measuring device is and what weighted ball is used? Also what height is it being dropped from?
Cool to hear more about the history. That's awesome that the research was done where the Pentagon is.
What is so funny about this? 😎😂
Sand for ever! 😅👍
Sand for the south edge 🤣
There needs to be more lecture type videos like this about turf out there. Keep up the good work.
