Unique Problem with smell
I have what I would consider a rather unique problem with the soil on one side of my small deck, facing north on the back of my house.
There is an absolutely horrible smell that manifested rather abruptly, two years ago, and only disappears once the weather (and ground) gets cool. From late May on and, In the middle of the afternoon, for a short two hour period, the soil in this area gets some sunlight and, at that time, the smell intensifies. It smells like a dead animal but, this has continued for two years, now, and an inch-by-inch inspection has revealed nothing. I've even got my nose down near the soil in an effort to locate it- no luck. Last year, I attempted to put down lime with a kitchen sifter, thinking that might abate the smell- not in the least. I don't any extra dirt or I would attempt covering the whole area (8'x20') with another three to four inches of soil in an effort to bury the smell.
Does anyone know of an enzyme product that I could spray on my soil to erradicate the smell without damaging my plants?
I'm just about sufficiently frustrated to go ahead and purchase soil and perhaps re-plant everything but, I surely would prefer a spray.
Any help would be greatly appreciated.
I hope that I posted this in the right area.
