For all those who are skeptics of going organic. I had a lawn in VA and for 5 years, every season I did the soil tests, the fertilization, and reseeding to no avail. I went with an organic lawn care team, and in the first season, a beautiful thick green lawn with no weeds. Now if anyone knows anything about the soil in VA, A LOT OF SAND! They did wonders! I am now in KY, and doing the organic thing on my own, this sight is extremely helpful.
On the dog poop issue, I have to agree, that having it laying around is more of a hazard than good for the lawn. there are products out there around 50$. You bury these containers in the yard and put the poop in it. It is basically a dog septic tank. A google search will bring it up. I use one, and there are no flies and no odor.
