- What's up everybody!? Surprise vid drop all about Potash, Potassium, K for lawns... How much do I need and Why? This is an important topic that gets overlooked a lot and I go into detail about the role of potassium in your turf, the types available, the best bang for your buck and how to do corrections.
This video was shot quickly and in a moment of inspiration from an online post today, between a multitude of other videos I'm working on. I'm sorry for not warning you and we will get back to our regularly scheduled live drops later this week.
Potassium helps maintain turgor pressure in the cells of the plant, resulting in a positive influence on drought tolerance, cold hardiness, and disease resistance. As a result, potassium deficiencies in turf may cause increased susceptibility to drought, winter injury, and disease. Therefore, potash is very important in your program.
I go into the difference between plant/foliar K and correcting soil deficiencies as there is a major difference there. I encourage you to check label rates on liquids to determine what you are actually getting in pounds or in other words, what you may not be getting. Higher potassium leading into summer can be the best summer fertilizer option in most cases.
I often recommend Sulfate of Potash which can at times be hard to find. turf supply stores tend to be the best bet and expect 32-40.00 per 50lb bag under those circumstances. for small mail order amounts:
amzn.to/2AnqAiP for a 5lb bag.

The 3rd number is exactly what I’ve been chasing trying to understand here lately, I do live in Florida and this helped me make sense of what’s going on, and what I can try and do. Thank you, Mr.Perry.
Nate Walls awesome. Let me know if I can help Nate
I'm in Central Texas. Zone 9.
Heavy clay soil over rock/kaliche.
My St. Augustine greens up with fish emulsion. I diluted it in a bucket and sloshed it on the grass. Not a perfect way, but it worked ok. Going to do it again. Cuz the "plastic snow" hurt it bad. Now, it's very yellow. I'm confident the fish emulsion will green it up again.
Great video, I'm starting to feel like I'm back in my favorite college class. Love the information. Thank you.
Steve Craig thank you Steve!
Such timely info. Just got my soil test back. My K was a whopping 2.9 ppm. Just starting out on this lawn care journey so appreciate all the info.
Also my ph is a little low 5.5 Will adding potassium lower the ph even more.
Man ... you are awesome .... I am interested in having my soil tested for the first time .... Florida here ... I have being with you and Allyn for a season already .... man .... you guys inspire me .... love the chemistry too, since I have health care education .... 😀😀😀
marciopdm awesome. Glad to help!
I live in Maryland and soil test results came back with very Low K. I put down a little 0-0-50 and noticed a big difference (positive) after a few weeks.
"For as little as $1 a month..." I died. Thanks sir for being brilliant and hilarious.
Thanks Michael!
I’m going to be making my own liquid this weekend hopefully. I’ve got some 46-0-0 and 0-0-50 that I’m going to mix some other goodies in with
Let us know how it went- have considered doing something similar.
Always love a deep dive into soil chemistry with JP! Thanks for the video!
Nicholas Zunker thanks Nick!
I live in panama city beach Florida and there has always been a ghost in the system with most st augustine and centiped lawns I deal with . This video may have given me magical knowledge!
Subscribed. My main take-away was not to try and fix it all in one application. My front Zoysia lawn soil test shows the love I put in. Now it's time to renovate my fenced in back lawn (put down Zoysia and let it fill in) which is 10,000 sq. ft., and I have high N, high P, low K, low Ca, 5.3 pH, 0.6 Fe (should be 2-4 range). Two dogs in the 55-65 pound range so I can't take the lawn to bare soil to seed properly, so I'll rough up the soil with a SunJoe dethatcher, bag the trash, throw down seed, mow and bag frequently enough to try and keep the existing grass & weed at 1.5"-2", and if 1 seed in 100 take root, I'll consider that a win because Zoysia will take over with a touch of love and herbicides at the right time. That, and I'll take a ton of plugs from the front to fill in the edges. Wish me luck!
Welcome! It looks like youve got all the info you need to grow great grass, let’s hope the dogs cooperate!
@@Lawncology I'm in Central Virginia, everything grows, but nothing truly thrives. I have some Rye and KBG in a 600' test patch, but I think the Zoysia will give a better layer of protection against muddy paws once it fills in. I don't know anybody around with KBG, so I'm testing. I'm a lawn care nerd...what can I say.
Having the right tool for the job. love it
Great Video... My soil test Said I needed 9.00 lbs per 1ksq( Soil Savvy) so I picked up some SOP 0-0-50 and I'm adding 1Lb per1k every month this season I'm glad to hear that I'm on the right track even if it might take me a while to get my Brumuda on track 👍 thanks again from central Valley California 😎
Camilo Ovalle awesome!! Keep it up!
Very good and informative video John! Thanks!
Barry Cavanaugh thanks Barry
JP, this was a super relevant topic of discussion. I'm on a macros & micros kick right now.
My issue in Central TX soil is that most everything is severely deficient (except for off-the-chart calcium). Super low N, higher P but just below "optimal," and then super low K. I test yearly before any applications to get a snapshot of my soil profile, and every year I get identical results. Only real improvement is slightly bringing pH from 7.8 to 6.9 over 4 years through the use of elemental sulfur. Should I just simply avoid any ferts with Phos since it's almost in optimal range❓
Pulled some plugs for a guy to do a SA. He sent his off to soil savvy. Results came back that they recommend 20 lbs/1000 of a MOP
I have recommended that we delay that application and split it up in the fall. Plus my three suppliers whom I’d love to name have no available SOP Pisses me off. We see low K here in northern Cincinnati all the time and I don’t like using high rates of MOP because of the higher salt index. Timely K talk. Thanks for the video
You’re saying 20lbs to the lawn or per acre or per thousand?? Hopefully not the last one.
Lawncology per 1000. Crazy
You made me doubt myself and I just double checked. 20.75/1000 of MOP. Haha
Paul Biel for real!? Please don’t put that out at once!!!!
Lawncology thank you
Very educational video! When you say "Put down half pound of 'K' per thousand", how often are you talking about? Once per season, twice per season? I have put down a half pound of sulfate of potash this spring and using the Bio-Stim pack. I have clay-ish soil my CECs are around 26. Once again, THANKS for the sharing of knowledge!
Instead of band aids, you wanna put the things into the soil, that treat the disease. One of my favorite sayings is "The Essence of Life is the Ability to Acquire & Ultilise Energy". I really get bugged by people who cannot cook for themselves, & or understand nutrition. I like this approach Sir. I only discovered you a cpl weeks ago, and Your one of the best I have found.
Thanks for the education, and your a likeable guy!
🇨🇦👊🏻👨🏻🏭✨💖🌿🌞🌱
Always very informative John! Thanks for taking the time to share your knowledge!
Pacific Northwest Lawns thanks Nate!
Great video. Currently unloading Sulfate of Potash Magnesia (0-0-21.5) on my lawn to tackle my K deficiency. The stuff has been great so far. Very low on chlorine.
Man, you broke that down !!!! I will be going to supply store Monday, Thanks
Is there a link to that map? This was really helpful, helped me understand the clay soil out here. And, not necessarily a bad thing. I learned in college we have the third richest soil content in the world. Before this was Silicon Valley, it was known as The Valley of the Hearts Delight - famous for all the stone fruit that grew here. Growing up it as all orchards - apricot, cherry, plums and prunes. I miss those beautiful orchards.
What would be a good use for the liquid potassium then if it provides no K for the soil?
Thank you low K is an issue I am addressing.
Hopefully this helps
"K-Load" is what we had before there was "K-Pop" 😎
You betcha 😂😂
More K for Kalbi 🥩
Sorry I’m 3 hours late... 1) I appreciate your knowledge and discussions on the lawn. 2) I can’t believe somebody hit thumbs down already. 3) I really love throwing fert with K... 😎 My lawn loves it. Keep it coming Perry! 🤙🏼
Don’s Lawns thanks Don!
I know I am on the right track when I just finished editing my video on potash throw down. Lol. Although I am still the student, and the professor has spoken.
Great minds buddy!
Just had a soil series flashback of limiting factors, laws of minimums and maximums. Haha! Just put out some 4-0-25 (.7lbs/1000) of SOP & sprayed 0-0-2 microgreene last week. Very low K & S here in Michigan. Thanks for the Roadmap John.
Awesome. You’re very welcome!
Side note: Just wanted to add that this is my first year going with N-ext products and I'm really impressed. I have Bio-stimulant pack, Greenepunch, and just received GreeneefFEct yesterday. Plan on also mixing in granular but going with low N rates.
Greg Aspenson that’s awesome
Great info! Glad that thread inspired this. I think it will help folks a lot.
It was timely for sure
Thank you for the posts you made. Perfection.
Thanks for the SOP on SOP!
Ha!
Was that a giant armadillo in the back ground at roughly 8 minutes?!!!!
Great info on this video. I have low potsium and this video was just what I was looking for.🍺
Ah dang, I just bought 2 gallons liquid potassium 0-0-25 that I can't return, Doh! 😫 My K is at 27ppm so I need a lot! Should I still try to find an SOP granular? Thanks for all your knowledge John, its amazing!
If you can, yes
Lawncology thanks!!
More awesome info! Love the channel and the hair!
Lol. Thank you
My state soil test from the guys here a NC states my K is low in my zoysia yard. They give me an index number of 38 with their scale that the normal is between 50 to 70. My P is really off the charts high (144 with their normal between 50 to 70). I just recently put out 10 lbs. of 5-0-20 which gave me 2 lbs of K and 1/2 lbs. of nitrogen per 1K sq. Ft. It also had 10% iron. It really respond well so far. I was thinking about doing this again in about 6 weeks for my last summer feeding. I also give a rotating diet of Micro-green, RGS, Air-8, Humic 12, and soon to be D-thatch. Oh yea, and Hydretain. What is your thoughts, especially about the 5-0-20?
I would imagine the soil-test levels across the US are derived from undisturbed areas within each state and not necessarily indicative of new construction in neighborhoods, where land is cleared and the soil disturbed from bulldozing. ~ mike in VA
I would say that’s a sound statement. I posted something similar to that on amazon earlier comment. No telling what suburban areas have done to cut and fill the yards.
How bout 0-0-2 and Air8 ?? Seems to be quick results in thickness and a deep green.
Also....got the shirt and hat today......love them !!!!!
Scott O'Hare awesome
Scott! Yes, low rates of K on those
Such a bad time for modem/router issues 😩 I heard potassium so I know this video is on point 💪 I’m going to try to tune back in to finish this for sure
Yeah man!
Lawncology Spot on man
I spent some time reading on potassium in 2019 it’s good to hear it from your perspective.. you know how the saying goes . “Trust but verify” thank you again for the verification 🙌🙏💪
Just applied GreenePhite last nite 💥 my lawn in NC is lacking K badly… this morning there was already visible results!
I went full rate GreenePhite thrown down with a 3oz/1000 of RGS 😁
@ 8:08 Is that a wolf? Are you going to be eaten? RUN! RUN! RUN!
Frank Schwarz lol
Love the teaching! Can I add Air-8 with Hydretain?
Wow! That was a lot of great information! Ty 👍🏼
Thank you!!
Good series. Looking forward to N and P
P will likely come next. And then some other fun things
Nice video!
Would you recommend mixing 0-0-29 acetate with a sop 0-0-53? .....Also how frequently should you be throwing down a 1/2lb of 0-0-53 if you have a K deficiency? Awesome video John. Great info.
Depends on how low you are and you wouldn’t need to do both at the same time but you could keep the acetate on hand for spraying at different or alternating times. A deficiency of 20ppm is 40lbs per acre or roughly 1lb per thousand.
Just curious where online folks are purchasing SOP. What’s the cost?
If we get what you suggested in the video, the 5lb bag, is it 5lbs per 1,000 square feet? What would the rate be for that ...
Shane Mallick that’s 2.5lbs of K
@@Lawncology Thank you sir
Nice video, I was low 13 pounds/1000 on my soil test, bringing it back over a 2 year time line.
Is your email question back?
Reiterating the importance of a soil test, I live in Eastern Iowa and have high Phos (P) but low Potassium (K). Per your map Iowa has sufficient K; however, that is not true for me. So while the map may be overall, on average, etc., it does not mean it's true for everyone.
You are correct. Many factors contribute to the native K load and whatever may be used as a medium for fill or soil load prior to growing turf on your property will absolutely affect the outcome.
Always educational!
Thank you Jason!
Something I was just made aware of in soil tests for row crop purposes... apparently base saturation percentage in mag and k is also something to keep in mind. Not ppm alone, so I’m curious what your thoughts are on BS% and how it applies here. Some soils seem to have less plant available K due to tie up, for sure. For a reference marker the recommendation I’ve seen is 3% to 6% K base sat with some variance for crop type. But that’s not a lawn, so what would be your experience with this measurement vs ppm of K as the only guidepost? Thanks :)
I actually did a video about this a year or two ago. Base saturation does play a role and it’s way to much to type here, but there are ranges and if for guideline purposes you had 65-75%Ca, 15-20%Mg, 3-5%K, gets you in a pretty good saturation zone. These can vary with soil type
Great content. A lot to absorb. Like the human body, chemistry is key. I once worked with an older gentleman who keeled over and died on the spot. Low potassium. I crap you negative.
😂😂
If one were to apply 0 0 50 granularity how often should they apply to bring the potassium up
Good info. I was just discussing SOP last week with some law nuts and leaning about it help with summer stress among other items. Went to purchase a soil reading and saw you are “sold out”. Did you exhaust all your nutrients already? Lol.
Rob Wright lol. No, backend app is not right. Working on it.0
Just got my soil test results. I'm in Illinois.
21-0-0 @ 2.25 lb/1000 sq. ft
0-0-60 @ 10.25 lb/1000 sq. ft
Thanks for the lesson.
Thanks for watching Wayne!!!
Since K is a salt can it worsen a dog urine issue. I already do my best to dilute the spots as soon as I start to see brown or I see them actively pee but not having much success. Just don’t want to make it worse if I add some K for stress relief.
No, you will be just fine.
Thanks for the video really liked it and i was wondering if i buy the yard mastery soil test online does it cost more to test after i get it or is it just the 35 dollars and ill get e-mailed results??
They send you the results via email
I had a soil test done 12 years ago and did not act upon it. My K was 47ppm and it was recommended that I apply 2.9 lbs/1000. Would this still be somewhat true after 12 years. I do mulch clippings and I have sandy soil. Any help would be appreciated.
Do you think it's ok to apply Muriate of Potash?
I can only find Muriate of Potash in my area. What's your thoughts in this? 0-0-60? Thanks
Lots of chlorine in that. Go to yardmastery and order 0-0-48
Dang! Soil test reading already sold out. :( I use the Prodiamine (0-0-7) and Dythopher (0-0-20) that is sold at yard mastery for pre-emergent. I wonder if this is helping with my K deficiency.
Hang tight.
Based on the general tone of the video, I would say that those doses of K helped strengthen your turf, short term. If you were/are(?) deficient, it will require more than just a season to get balanced. The prodiamine, for example, is only 7% K. If you put down 1 lb/1000 sqft, you are putting 0.07 lbs/1000 sqft. I’m pretty sure that if you are deficient, it is by more than that. 🤏🏼And a lot to unpack in a Comment. :) I get my tests from LCN.
@@goodrabbi7176 I do split applications of prodiamine in spring at 3 lb/1000 sqft for a total of 6 lb/1000 sqft. Thats .42 lbs K in spring. Then I do a Fall application of Dythopher which is (0-0-20) and I believe the bag rate on that is 3 lb /1000 sqft .6 lbs of K in fall. So I guess I am basically throwing down 1 lb in a season. I guess I am already doing what John is recommending. Spreading out my applications of K throughout the season.
I am considering the Yard Mastery summer stress blend for my summer Fert application as its 7-0-20. But I also got some of that 9-0-1 GreenStart that I planned to use as my summer fert. Maybe 1.6 lbs K per season is too much?? Thoughts?
Have you actually had a previous soil test? Or will this be your first? How did you come to the conclusion that you are deficient?
Can you post a link for the SOP you’d recommend for a backpack sprayer?

Great info and as always...Great video. When will the soil test be available to purchase on your site... It is out of stock
Stephane Durand this afternoon it should be live. We’re working on it now
Cool!!! I will have my test done here in Canada and purchase it when I get the result back.I think you prefer the sample to be taken between 3-6"... Am I correct?
That is correct
Thank you. Ok, from a practical level how many lbs of potassium do you recommend for a lawn showing just below the ppm.. maybe give the dose needed for the full range of potassium levels in soils deficient in K..Assume the soil is clay and sand..thanks
If you’re right on the edge 1-2lbs
@@Lawncology thank you
Hey John, I just got a soil test back and hoped you could help to guide me in the right direction. PH wrong and multiple deficiencies. Could you advise how I’d send it to you? Many thanks👍

Hi, my soil test says my K is 52 lb/A and rated as Low. How much more K do I need to bring to ideal levels for my lawn in VA. Thanks
You were going to need somewhere between one and a half to 2 1/2 pounds per thousand to get your K levels up to adequate. I wouldn’t apply this all at once, split it up into a few applications
Lawncology when u say split it up into a few apps could u be more specific ..like over the course of the growing season or once a month ...TIA

Hi, I found 0-0-50 at local store but it had 2% chlorine in it. Does it effect anything. There are other granular fert 0-0-25 which has 25% chlorine. The reason I ask coz they sell stuff for pros and not sure if i can use the same on home lawn. Please advise. Thanks
The 0-0-50 was sulfate of potash correct? This would be better than muriate of potash
Lawncology Yes, it says so. Below is the link to its label. www.siteone.com/pdf/sdsPDF?skuId=3783&resourceId=15732 I was wondering if that chlorine is ok for home lawns. Thanks a lot for your replies.
Kalyan V yes. You are totally fine with this. Chlorine is in high amounts in MOP and typically you would t see much if any in SOP. This is a good choice.
Lawncology Thank you so much. One last thing, as you advised earlier, if I have to put 1.5 lb to 2.5 lb of K and not putting more than 0.5 lb per 1k at one time. How long should I wait to applying K again?
If my soil test said higher “K”, but granted that was a little after I already threw down CX (threw down first because I just moved in March) would something like XGN be bad to use this summer since it’s an 8-1-8? Thought would be better for summer than my CX.
What's your take on adding magnesium sulfate (Epsom salt) to the lawn? I try to add it at a rate of a half pound per 1k.
Cole Spolaric works great. KMS is another wonderful product
I'm in NE Florida and have low K. Just bought the Yard Mastery 0-0-48 SOP. Bag says 2 lbs per 1000. Is that rate too much?
I had a soil test after neflecting my old lawn to kill it off for months and had 52ppm in K in socal based on yardmastery test. Looking for summer applications with n-ext products and have the 7-0-0 to keep nitrogen low. Do i need to add greenphite or can i just use sea-k during the heat? TTTF in socal. Thank you in advance
What about low potassium? Hi K?
any plans to add a fert to your lineup with more potassium?
Not sure about for DIY. On the pro side, we sell a 0-0-28si, 0-0-32 Phite, and we deal in pallets of SOP 0-0-50
@@Lawncology would be great to round out an all liquid program! Lawn supply company has some neat offerings in the potassium space.
@@cmokula93 I maintain that for the amount of K needed, granular or dry is better. It’s kind of a pounds vs ounces thing
