I am about to have a load of 50/50 soil delivered to add to my beds. It consists of 50% topsoil and 50% composted chicken and turkey manure. Does this sound like a disaster waiting to happen as far as disease spreading potential? The stuff looks like rich dark dirt, but when it is first delivered it does have a poo smell to it. Am I paranoid?Actually I know I am, but in this particular instance, am I? Thanks.
