^^^ That.

If you don't have a soil test, anything high in nitrogen and low in everything else is a good starting point. There's no sense in throwing resources at a lawn if you don't know if they're needed.

Haven't done test... just put down some 30-0-8 just before we got a got 1.5 inch soaking of rain... i'm sure it'll help some... grass is tired after dry, warm summer...

That's perfect! And about the normal ratio for high nitrogen, low everything else.

And yep, I'm waiting for rainfall myself. It's cloudy enough that the solar panel in the window can't charge my power master, but refuses to rain...

There's a website called "NPK of Everything Organic". It will surprise you what organic amendment is VERY HIGH in nitrogen. Since I'm not doing chemicals here, I'm going to have to wait 2 yrs for the dog hair to compost. That and feathers (which I have no access to). But, PetSmart and PetCo's grooming septs are now saving me their dog hair clippings. I'm adding it to the soil that I made only out of decomposed wood chip (because I could get that free and I needed quite a bit). So, now I'm adding dog hair to increase the nitrogen. Another good idea is to use Hairy Vetch as a cover crop. It fixes nitrogen as it roots.

I know this isn't want you had asked, but I felt that the information was still helpful.

I use soybean meal, myself. It decays quickly, and at 7% nitrogen and fairly cheap at the moment, 15 pounds per thousand is a good feed.

My September first feeding is already starting to come into play.

That's worth checking into - thanks for the tip. Can you suggest something I can use to add iron to the soil?

Milorganite contains about four percent iron (they use it as a binder). Compost that had red meat in it will be naturally higher in iron but, of course, make sure it hit high temperatures through the entire pile or... Ditto with composted carnivore or omnivore feces.

Personally, I'd stick with the Milorganite unless using commercial compost.

Last on the list is iron sulfate, which is acceptable for an OMRI program and I do use it myself--sprayed once yearly at about 4 oz per thousand square feet only.
