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
I've put on 2 light doses of DEF over the past 3 weeks. I have NOTICEABLE improvement. And I'm doing 5 acres of yard. Probably the best looking yard I've had in 5 years. Lighter coats with a little more frequency is better than a heavy dose. (you never know what mother nature will throw at you). Also...you need to water it in. Nitrogen is not absorbed by the leaves, but rather thru the roots.
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! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-sHLN88LhmmM.html
I would consider cutting the grass. You have approx 4 inch’s of grass length if not more. That would stop the product from reaching the ground. Also I concur what another commenter said about the iron in one mix but not both. But I’d defo cut the grass short. Thanks for taking the time to share your content. I have wondered as I’ve seen the same about the def or ad blue ( uk). Thanks for
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!
I'm curious why you added the iron to the fert but not to the DEF? It would be a better comparison to either use iron on all 3 or none. Thanks for the cost per oz. breakdown, I was surprised to see such a wide margin in cost/1k sq. ft.
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
Did the fert and iron plot also get watered in? From several videos i've watched, its been said that the IRON should not be watered in. Otherwise it will take longer to see results. But DEF has to be watered in ASAP.
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.
@@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.
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
Not even close to a fair comparison since DEF is only Nitrogen.... So you sprayed just Nitrogen in one plot & super charged the already good fertilizer with Iron which is where you get most of your dark green from 😂😂
You need to use a high volume sprayer I think maybe. Those low pressure back packs are good for weeds and pests but not enough volume for fertilizer use. Just my opinion though
The fact we saw no conclusive results means your experiment was skewed by the rain. You added iron to your "fertilizer" but not the DEF. There should have been a clear difference since iron will boost photosynthesis (making the grass greener). Next time take out the iron from both leaving an actual apples to apples comparison and do it with no rain in the forecast.
@@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
@@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
