Honestly I think the results got screwed up because I ended up with a ton of rain that week and I think it messes up the whole test. I may have to redo the experiment

Jersey lawn, application was 5/13, checked back on 5/17

That’s what I figured, how long did you wait after application to water? I just gave it a quick squirt with the hose. And I did have a lot of rain that week I think everything got washed out

@dnotso4574 what are you using to spray and how much are you mixing? I have about 4 acres I treat wanting to switch to DEF and iron. I have a 25 gallon pull behind sprayer

@@kbrown4023your better off mixing up your own urea for an area that large, it’ll be cheaper too check this new video Cheaper than DEF! The cheapest fertilizer! kzfaq.info/get/bejne/qa58gZtpsc7RnYE.html

Thank you for the comment I’ll consider cutting it shorter when I retry the experiment though I was under the impression that the def was supposed to be absorbed by the grass leaves instead of the ground. I’ll do a little more research for the next video. Thanks for watching!

@@AllDIYNoSkills You are correct. DEF does not need to get down to the roots. Its a fast release, fast acting, fert. Does not last very long.

So I wanted to see how the DEF compares to what I normally put down but I think everything got screwed up because it ended up raining all week so it might have washed everything out. I also want to clarify the math a little more because it may not be a clear reflection of the nitrogen costs and comparison

Is that the same as DEF? I just never heard of it that’s why I’m asking

@@AllDIYNoSkills google “traveller def”

So no the fert and iron plots did not get watered in initially. The recommended application rate of the fert I used is pretty low nitrogen for the area but that night and the rest of the week it rained a lot so my guess is everything got washed out and ruined the experiment which is why there was no noticeable difference.

@@AllDIYNoSkills any chance of re doing the experiment? or have you noticed any different results after the rain?.

@@manuelvelasco8394 yes I am planning on redoing the experiment in the future. I also made a video with more accurate math on the nitrogen in fertilizers

Yea I didn't chance letting DEF sit, however i did apply with some chelated iron along with DEF and a little surfactant and watered it in immediately. A month ago I also previously in the evening did a foliage app of iron and watered it in in the morning. Honestly the green up was almost the same when i watered the iron in with the DEF. I did 12 Ounces for 2500 sq feet. They recommend 8 oz per 1000 sq feet, expensive lol.

@@CTheTechGuru see when I do liquid iron and my other liquid fertilizer I don’t worry about watering in right away. I did video with the math but I am also planning on going over more math.

Yup I didn’t see a difference

Yes I did a video comparing the costs including the Walmart version

So it was by application rate which upon reflection does not accurately represent the nitrogen per pound which I will remedy with a new video and more accurate numbers

Agreed which is why I’m in the works to make a more correct video in terms of the math and also in comparison results

It has about .9 lb of N per gallon, this DEF, assuming that the 'urea' is UAN28. The rest is water.

@@SmooveBee1 correct that’s what the new math I did works out to about

Actually if you practice your pacing you can put down the right amount of product which is usually measured in gallons per 1000 square feet

Hmm I didn’t notice I’ll have to check back this week. I think I’m going to redo the experiment in a couple weeks to see if there’s better results

Correct the rain screwed it all up. Already planning a follow up video, maybe just def alone to see if there is a difference between treated and not

@@AllDIYNoSkills I've been using DEF in my lawn spoon feeding every two to three weeks the last two seasons. I wouldn't say they're extraordinary results but it's been good. Then add iron and I've got the best looking lawn on the block. It's a good "poor man's" lawn regimen.

@@bretmizera9600 try getting some urea and mixing your own def, 0.5 pounds urea per gallon gives you same nitrogen content per 1000 sq ft and much cheaper. Probably going to do a video tomorrow about that and the cost

I wanted to compare just def to what I normally use, but the experiment was tainted by too much rain over the week

@@AllDIYNoSkills Ahh, I gotcha. It happens👍

@@Efferri I’m going to retry in a couple weeks but I’m going to do just def vs no treatment to see if we can notice a difference

@@AllDIYNoSkills I'll be interested to see the results

@@Efferri me too because everyone keeps claiming that DEF is like a cheap wonder drug for the lawn but I did a cost analysis video which shows it’s not the cheapest. Compared to urea even the Walmart brand is a lot more. In that video I used the granular application rate for urea which yields 4x more nitrogen per 1000 square feet. If you dilute it and do a liquid application for the same rate of nitrogen per 1000 of 0.2 lbs nitrogen as DEF your at less than half the price of the Walmart brand
