My yard smells. It is heavy clay and when it rains, it holds moisture and
turns green with either algae or mold. (I have had 2 loads of top soil
brought in, tilled it and amended it per the dept. of agriculture. It
always started out great, then turns back to clay. Overall, I have spent
about 3K on the back yard)

Oddly enough, where it smells the worst is in an area that gets full sun to
bright shade all day. The yard is graded correctly, it slopes down, away
from the house. I do not have any trees in the yard, but there are very
tall pine tree's behind the yard.

My question is what can I put on it to neutralize the smell?
I am getting ready to deck the remaining yard in so I don't care if it kills
the grass, (what little there is). I also have 2 dogs and the smell of
urine stays forever. Baking soda doesn't work and I have actually tried
Febreeze. It's just a rank smell.

Thanks!
