The closer you get the mic is to the talent’s mouth the lower the ambient sounds will be in relation to the voice. However, you will still hear some background ambience. Does the audience see that the person’s outside? What about the cows? If they see them, they’ll accept the sound of them. If for some reason you absolutely need to eliminate all ambient sounds you’ll have to do ADR in post.
