Urea is 46 % nitrogen and nothing else. No sulfur, no potassium, and no micronutrients such as iron. This why they have a bad name and give any one who applies liquids to lawns a bad name because of their cheap formulations. I gladly spend $5 or more per 1000 sq ft so that I am doing more than just spraying urea on a lawn.
It looks like this time was TruPower 3 EPA#228-551 and Andersons Fertilizer with .2% Merit insecticide. EPA reg # 432-1349-9198
The first application was Barricade EPA#100-1139
Topdressing is applying a thin layer of material onto a lawn. In your case, that material should be about 1/4-1/2" of finely screened compost. You are a candidate for a machine to come and either blow or spread that material. It is rough work to spread more than a yard of compost. cgaengineer said you need over 50 yards.
It looks like i would need 84yards at a 1/2". So what is this stuff, and where do i get it. I can get black compost/mulch from my town for free. We are only talking a few yards at a time. I am just basciclly raking out mulch? I am interested, but how does a 1/2" of this help my soil structure. Do you have any pics/links?
