I worked at one of Canada's busiest airports in the late 80's and 90's. We only used granulated urea to salt taxiways and the runways during the winter. Incredible!! Would melt snow for days if it was just a dusting but would of course cut through ice leaving the runways dry and clear. The best part, the green grass near the areas we dropped the urea were so healthy, green, and lush in the spring.

Bored at work, come up on your video, I’m glad you talked about mental health for men. Two years ago my brother lost his fight with his mental illness. Good video I’ll try the Def in my lawn.

[@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.

[@blowinsmokeupyour]

15% is not weak at all

[@100pyatt]

AGREED, it's only $18 for 50 lbs 46-0-0 pellets

[@wojciechpestkowski8714]

correct, even in europe. 25kg (55 lbs) of urea consisting 46% N costs 20 US dollars. So to get 15% solution of N you pay around 0,25 dollar per litre, so roughly 1 US dollar per gallon. In this video 2,5 gallons 15% nitrogen DEF costs 10 dollars. So you get 4 dollars per gallon. So it is here 3,5-4 times cheaper just to mix it yourself.

[@mfalc01]

Why cant we get a simple mix ratio, oz of def to water?

[@chuckredd9131]

@PrincessCutLawnCare 1 year ago (edited) Application Rates Per 1k sqft: (Mixed w 1 gallon of water per 1ksqft) Low Rate (0.10 lbs of N) : 9.5 oz per 1k sqft Medium Rate (0.15 lbs of N): 14.25 oz per 1k sqft High Rate (0.20 lbs of N): 19 oz per 1k sqft *BE SURE TO MIX WITH 1 GALLON OF WATER PER 1K SQFT AND WATER IN AFTER APPLICATION

Urea is just piss and it's perfect for the grass

[@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.

[@juniormorris8674]

I do use burnt motor oil and diesel. Sorry

[@LReno-di9cm]

Mixture PLEASE. DONT MAKE US SEARCH

[@Thejrb11]

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

[@767harsh]

Could you help to advise how much can I add in spectracide bottle for broadcast spray 1000 sq ft? Typically a 32 oz bottle covers about 5300 sq ft. lawn.

[@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

[@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.

[@BillyBob-vz8ol]

I deal with semi trucks every day actually own one. Def is a scam. Semi trucks have DPF diesel particulate filter As of 2024 cars must have a GPF. Many truckers closed their business because of these😊

[@williamcampbell-h5p]

Is DEF pet friendly on your lawn?

[@UncleFjester]

If you regularly put fertilizer on your grass it should already be green, this will help but won't give the results this color colorected video shows. Adding 10 oz of 34% nitrogen, 3.4 oz of nitrogen in the 10 oz. to a gallon is an application rate of only 3.4oz per gallon. Nothing to write home about or ground breaking in the fertilizer world. You just got played by KZbins algo's and the cloned video makers. Thank me later?

[@GosselinFarmsEdGosselin]

What you don't realize is... DEF fluid has made the price and availability of agricultural fertilizer go up and much harder to get. And it's far from the cheapest liquid fertilizer, otherwise farmers would be buying it by the rail car load. BTW, it's also the stupidest thing they've done to engines! JD has some of the most expensive and least reliable Def systems.. Also, comparing liquid to dry fertilizer, is very misleading... Just saying...

[@nyacoustics8373]

[@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.

[@Eli-qr9hc]

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.
