Got my soil test back and just need to feed nitrogen and raise PH a bit. Been adding lime. Now I need nitrogen only fertilizer in a few weeks. What's the best source? Seems like everything around me at HD Lowe's doesn't say exactly what it is or is mixed with other stuff. Maybe I should order ammonium sulfate or Urea from somewhere?

Urea 46-0-0. Might not be available at retail garden centers or the big box stores, but would available at ag feed & seed stores in the quantity you need for a lawn. You near a Site One Landscape Supply? they should have it.

I'm not near one. Have a very small backyard with Bermuda. Just read that I would use DEF. Seems like if I get the calculations correct a jig would last me a long while.

To where did you send this soil test? Your local county agent?

Well I suppose you can being, as I understand, a 15-0-0 urea solution.

Sure you just wouldn’t want to use a product specifically formulated for lawns? Small lawn, can’t that expensive.

Application rate of a spray fertilizer may be a good bit less per 1000 sq ft than a granular product - possible concern over of “burning” the lawn (like a dog pissing on a lawn)? Take that into consideration.

Right. Im checking out all the conversions and will start at maybe .1lbN per 1ksf. Should be 10oz def per 1000sf. Only have 400sf where I'll be using it so maybe start at 4 oz or less and see how it responds.

Would Milorganite work? It's what I use

Milorganite is 4% phosphorus. I don’t use it but it might have sulfur in it which would counter his use of lime.

What is the grass? Ammonium sulfate could be a problem if trying to raise pH.

I forget the type of Bermuda. Mow with a hand reel mower a few times per week. Read the same thing about the ammonium sulfate. Was gonna try the urea.

Ewing might have something you’re looking for. They have a bunch of different types of fertilizers.
