I have dirt that smells like rot. How can I make it smell better?

Question

The house is in the mountains in which the porch was rmoved to install a new one. When the construction team removed the porch, I noticed a terrible odor eminating from the dirt. It smells like dead animals or something. I have searched the ground but see no signs of animal bones or anything. I dont want the porch put up until the smell can be taken care of. Can someone give me some idea of what can be causing this problem, and how can I get rid of it.

Answer 1

Lime you get it at a Lowes or garden store sprinkle it over the area and let it just stay there. they can build the new porch right over it. About once a year after that throw a few handfuls under the new porch to just keep it fresh. It does not hurt the soil it's what they use on football fields to make the white lines.

Answer 2

Fungus growth can be the source of it. Why don't you have the ground excavated and put new soil on it.
