Finally a good use for DEF

[@d.williams6891]

I’m glad to see DEF being of use for something. I haven’t needed it in 3 years after I hit a really big pothole and some parts fell of my truck that used DEF, but I may have to buy some jugs to spray on my lawn now! 😂

Hi Jesse - Thanks for all the work on this great channel! I’m in my second season of spoon feeding DEF and like the results so far. Also thinking of overseeding with Blackout this fall. Thanks again from another Northern Midwesterner - NE Wisconsin.

[@MrHarryhere69]

Urea in solid form also works great for melting Ice. Little fun fact.

[@ScoutFX]

I prefer AMS for the darker green up (a tip I learned from George), but I do use def in my backpack sprayer when I spray for weeds.

[@briannovoa7706]

Ya bro!! finally I have got my Gras/weed killer from gas pump for years!) Thanks for the tip

[@robertlevy4613]

I definitely stand by DEF. I used it for my fall nitrogen blitz last year and it made a gigantic difference. Grass recovered from Texas heat between September to November and I was able to keep mowing almost until December. And it’s cheaper than the 27-0-0 Simple Lawn Solutions Growth and Green

[@Firstcause5666]

Been spoon feeding with this for awhile along with a little cheap corn syrup mixed in. Works great.

[@LegendaryLawnCare89]

I appreciate the effort you both put in creating that video, Jesse and George. It was informative, engaging and I enjoyed every bit of it.

Awesome video, man! Question for you: With a foilar application, what do you recommend as a dwell time? 4 hours, then water in or apply in the evening and then water in the morning?

[@broseph1371]

I had always heard that it was detrimental to grass and anywhere it was spilled like it was a poison made of many chemical compounds, but if this is the case then i will give it a try on my lawn.

[@zenabu80]

I have seen a few videos on this. It's the same thing you use on crop fields. I wonder if it would work in my vegetable garden?

[@ninolama]

I learned this last year in George's channel. I like both channels though. 😅

[@robertlevy4613]

Both channels are awesome

[@zenabu80]

Auto part stores have it. Also some gas stations and truck stops will have it also in the box.

[@samquesnel1370]

Don't buy it from the corner of gas stations. You'll pay $20 if you buy it from stinson's in Ottawa, you can get it for $8 a bottle

[@Danomite99]

Not sure if you have done a video on Magesium sulphate aka epsom salts yet, but I just applied some for the first time. (with a control area) and wow. It’s even darker. Get the one that smells like lavender, and have scented turf lol Ps: I already apply mostly liquids Iron sulphate, Nitrogenetc.. -and cut at 0.5” with reel. This is no joke 👌

[@midwesternoutdoorsandnatur8272]

This has been done before and granular is actually cheaper by 3 times roughly. If you are looking for weak N and ease of application it works but doesn’t justify the time spent for amount of N you actually get by volume.

[@YourLocalCountryBoy23]

Herees a trick load your truck up Attach a sprayer and attachemnt to your DEF tank so you still get DEF but the trucks dont use it when deleted then you got a mobile sprayer for the pastures and or fields that you want to have grss on😂

[@Jedpack]

You’re a wizard Harry

[@keithdutton1246]

So, I liked and subscribed, because I appreciated your in video add for mental health. My wife is a therapist. Anyway, do you have any advice for using DEF for drip irrigation on food day for my flowers and vegetables?

[@bigbearbear5458]

Can you use both DEF and Feature together as a foliar spray to get the grass super dark green super quick? I've done both separately and am wondering if I should combine the 2 products.

[@thedroneradventures8374]

Great for nitrogen but what about the missing compounds a lawn needs. Can they be added some how or do you still need to lay down a good slow release fertilizer

[@kanyeeastlolz]

Use this for the fall autumn blitz?

[@Chad03Cobra]

Can you mix both def and the dark green iron together?

[@tazareal]

When I apply DEF with a hose-end sprayer, I add a little food coloring, so I can see when it runs out. Another use for DEF: Add some to weed killer, the urea gets the weeds to uptake the chemical faster.

[@thedj5914]

Thanks 👍

[@bobprivate8575]

If it's a root-absorption herbicide, that can help. But most are foliage absorption. For them, add some liquid dish soap to break down the water's surface tension. Urea (DEF or other) can also help with uptake of systemic insecticides such as Imidacloprid.

[@tazareal]

@@bobprivate8575 Sounds like a good idea. I'd point out that I used a herbicide with quinclorac, added DEF and citric acid, and that just murdered my crabgrass. However there may have been a surfactant (ie, soap) in the herbicide, as a non-active thus unlisted ingredient. So I may have just lucked out. Anyway, the daggone crabgrass is gone!

[@tazareal]

Menards sells herbicide/insecticide coloring so you see where it's sprayed and/or level in hose-end sprayers. $20 a bottle! I think I paid $1.19 for a assortment of food coloring in the bakery section of the supermarket.

[@brbr4281]

At what time of day would you apply this? Would you apply before or after it rains?

[@peterscanlon9727]

Good video, thank you. Since it’s foliar treatment, would a surfactant or MSO help it stick better?

Can this be used on perennial foliage to stimulate growth?

[@timgerber8726]

As a farmer I am a little taken back by this video. Come on man seriously. All these people are going to be going out and improperly using DEF. Buy a bag of granular and spread if you must. What you are not telling everyone is the granular will stay there. Stay in the soil for the uptake of the grass. You spray the def on your lawn and get a heavy rain and bam it leaches lower into the soil then the roots can use or runs off into the storm water system. Not only is your idea bad for the pocket book but not a great environment standpoint. Just my 2 cents here but kind of annoyed. Why not tell everyone to spread waste oil on their lawns? Yes they will grow like crazy but people know better for the environment

[@soyoucametosee7860]

Yeah. If you pay attention, he tells you that DEF is not a good choice. He is also pointing out that your DEF mandated equipment is producing run off. DEF is one of those stupid ideas that environmentalists came up with. It just shifts the focus.

[@lordgarth1]

People already use water soluble urea when they want some immediate release nitrogen. This is just a cheaper source. No difference and not improperly using anything.

[@tonypointer7026]

Ah the globalist want farmers from using any nitrogen on fields

[@Danomite99]

I’m not sure why you are concerned here. Nitrogen is nitrogen. Liquid fertilizer applications are the preferred choice for golf courses and sports fields. Def fluid has 2 ingredients 32.5% nitrogen, and water. Whether you buy a granular fertilizer and mix it, or buy this pre-mixed, it’s the same concept. How you apply liquids is the only real concern. -when applied correctly, (spoon fed application every 2 weeks) it should be mixed with a surfactant. This allows the grass plant to uptake the nitrogen via a foliage process. This is not a spray and soak application.

[@GerenaJonathan]

Man your neighbor is like DAMN there goes the green grass guy again....

[@LucianoBradley12]

How long after spraying weed killer to spray DEF on the lawn? I used tenacity

Do you have to water it in after or let it absorb through the leaves?

[@pauljones6321]

As I suspected, after doing the math, the cost of 46-0-0 from my local professional landscape supplier is 37% less than Blue Def and much easier to apply.

[@WeShallC]

I used DEF last season and had amazing results. Has anyone experimented W/ other ferts/nutrients. I have planted fish tanks and use liquid ferts (seachem) for optimal plant growth. I have often wondered about putting a mollycoddle of seachem products and throwing her down on the lawn using the backpack sprayer. Since it’s essentially the same micro/macro that my lawn needs.

[@dlandes14]

We have a gravel area where my dogs pee every time when they go out. Sometimes after a brisk rain I'm sure there's some run off into this low spot just off the gravel. It's always the darkest thickest grass in my yard. I'm sure if you found a way to dilute it enough, could be a viable option lol

[@WeShallC]

@@dlandes14 unless I spray after he goes (who’s doing that?) I tend to treat bare spots with some quick patch work.

[@dlandes14]

@WeShallC oh I meant try to collect the dog pee and tank mix it with water and spray it lol. The little rings around the dog spots are always super lush. If you found a way to dilute it just right.... free fertilizer!

[@kenshinhimura9387]

185 grams of calcium nitrate will make 50 gallons of nutrient solution and you can spray it directly on the lawn. No dilution needed and you could use it every time you water if you want.

[@Raul28153]

I use urea. it is 46% nitrogen and I don't feel weird about using something that makes me think about petroleum fuel

[@georgekamzik1274]

how long till you water your grass

[@elian222]

If you apply the liquid N from DEF fluid at a rate of .2 lbs N/1K sq ft as you recommend, then how often would you reapply at the same rate to best maintain during the turf's growing season the nice green-up color achieved during the first application? Every two weeks I'd think while observing for the duration of the green-up and adjusting from there.

[@LAWNLIFE]

Every 1 to 2 weeks will keep your lawn looking great

[@raymi9612]

How about drip fertigation for vegetables? How much Urea solution do I have to use for 1000 litres of water via drip irigating?

As a newbie, would you explain why use the 15-0-0 vs let’s say a 28-0-0 or higher? Thank you

[@shoudoun1234]

The number is the percentage 15% nitrogen vs 46% nitrogen. It's just the concentration of nitrogen in the product. There is only a certain amount of nitrogen you want to put on your lawn per 1000sqft. So with the 46-0-0 you would use less product compared to the 15-0-0 to get the desired amount of nitrogen down on your lawn.

[@kenshinhimura9387]

I prefer calcium nitrate. 185 grams will make 50 gallons of nutrient solution. With the added benefit of the calcium on top of the nitrogen.

[@nyacoustics8373]

what if you have a small lawn with 700 square feet? how much do you put down ?

[@FogataMexicana]

14.7 ounces of DEF in one gallon of water for 700 square feet. At 21 ounces per 1000 square feet he says at (5:23) that’s 2.1 ounces per 100 square feet. So 10x2.1 = 21 ounces. Applying any foliar spray should be done when the sun is low in the sky so early morning or in the evening. Ideally for slower evaporation.
