Question

is the such a thing as being addicted of like the smell of farms and if so what is it called

Answer 1

I believe a person can be addicted to any kind of smell he fancies. My sister loves the smell of erasers and tires (practically anything that's made of rubber). For me, I love the smell of petrol, leather and freshly cut grass. Don't know the specific name for such addiction but I personally call it "weird addiction".

Answer 2

The addiction of farm smells:
the scent that follows your boots, wherever they step

I would call it homesickness for the familiar scents of home.
